Types of Stainless Steel Strip
 

Grade 301 Stainless Steel
Grade 301 stainless steel is comprised of additions of chromium and nickel and has exceptionally corrosion resistance. It is both strong and ductile when cold worked. With these properties, grade 301 stainless steel is commonly used in welding, forming and drawing.

 

Grade 304 Stainless Steel
The most common variety of stainless steel, and one that is frequently used in Marlin Steel’s custom wire basket designs because of its versatility. Even among steel alloys, grade 304 stainless steel is noteworthy for its high tensile strength—roughly 621 MPa (90 ksi). Like most stainless steel, grade 304 has a high maximum operating temperature (about 870˚C). This combination of high tensile strength, temperature resistance, and corrosion resistance makes grade 304 stainless steel ideal for a wide variety of applications.

 

Grade 316 Stainless Steel
Another common variety of austenitic stainless steel, grade 316 stainless has a high tensile strength of 579 MPa (84 ksi) and a maximum use temperature of around 800˚C (1,472˚F). While having a lower tensile strength and temperature tolerance than grade 304 stainless steel, grade 316 stainless has a better resistance to chlorides (like salt) than 304 alloy does. This makes it a preferred choice for any application involving exposure to salt or other chlorides.

 

Grade 321 Stainless Steel
Grade 321 stainless steel has added titanium to withstand corrosion from chemicals and high temperatures. It can resist oxidation up to 1500 degrees fahrenheit and has higher stress rupture properties than grade 304 stainless steel. It is also non-magnetic and can retain its strength at low temperatures.

 

Grade 420 Stainless Steel
This grade has the highest hardness among all the stainless steel grades with 12% chromium - 50HRC. Grade 420 also offers good ductility and corrosion resistance, especially to alkalis, fresh water, foods, and mild acids. Cutlery is commonly made with grade 420 stainless steel due to its corrosion resistance, though pitting can occur with continued exposure to certain food substances.

 

Grade 430 Stainless Steel
While not as strong as either of the austenitic alloys highlighted above, grade 430 stainless steel does have an especially good resistance against nitric acid. Although the tensile strength of 450 MPa (65 ksi) is lower than most austenitic stainless steels, it’s still more than strong enough for many heavy-duty applications.

304l Stainless Steel Strip

01.Raw material selection

The first step in the process is choosing the right raw materials. Stainless steel strips can be made from a variety of grades of stainless steel, but the specific grade chosen depends on the application requirements. The raw materials must also be tested for quality, chemical composition, and mechanical properties.

02.Slitting

Slitting involves cutting the coils into narrower strips of the desired width using a slitter machine. The slit edges must be smooth and free from burrs.

03.Annealing

Annealing is the process of heating the strips to a specific temperature and then cooling them slowly. This softens the steel, making it more malleable and easier to work with.

04.Rolling

The annealed strips are then rolled to their final thickness using a rolling mill. The rolling process requires precise control to achieve the desired thickness and finish.

05.Pickling

Pickling is the process of removing any surface contaminants from the strips using an acid solution. This prepares the surface for the final steps in the production process.

06.Polishing

The final step in the process is polishing the strips to achieve the desired finish. This can involve a variety of polishing techniques, such as mechanical polishing or electropolishing.

Rolling And Bright Annealing Process

  • The first time rolling process: Our workers operate the advanced mill calender to make the hot rolled stainless steel mother coil with a thickness of 2.0mm~3.0mm into a stainless steel strip coil with a thickness range of 0.2mm~1.0mm. The first time bright annealing process: The 0.2mm~1.0mm thickness stainless steel strip is processed for bright annealing treatment. The strip can be fast cooled by the the continuous annealing line. The traveling speed of the stainless steel strip on the line is around 60m~80m/min.
  • The second time rolling process: After first time bright annealing process, continuing rolling the stainless steel strip with 0.2mm~1.0mm thickness into a new stainless steel strip with a thickness of 0.1mm~0.3mm.
  • The third time rolling process: After second time bright annealing process, continuing rolling the stainless steel strip with 0.1mm~0.3mm thickness into a new stainless steel strip with a thickness of 0.06mm~0.15mm.
  • The forth time rolling process: After third time bright annealing process, continuing rolling the stainless steel strip with 0.06mm~0.15mm thickness into a new stainless steel strip foil with a thickness of 0.02mm~0.1mm.

Degrease Cleaning Process
Cleaning the residual oil on the surface of the stainless steel strip due to the stains during the rolling process.The principle is to use the chemical reaction (saponification reaction) between the alkaline agent and the grease on the surface of the steel strip to remove the grease.The speed of the whole unit line is about 60meters/min, which can handle stainless steel strip with 0.02mm-1.0mm thickness.

4

Tension Straightening Process
When stainless steel strip is rolled on a 20-high rolling mill with a thickness of 0.02mm-0.8mm, it is a difficult-to-deform metal.Defects formed when the reduction of half the width of the steel strip is slightly larger.It behaves like a very wide unilateral wave. This wave has a very low amplitude and a very long wavelength.In this process, the steel strip passes through a set of slightly offset rollers and bends, causing the steel strip to slightly stretch.After straightening, the stress distribution in the entire steel strip is more uniform and the plate shape is more straight.

5

Slitting Process
For different thickness of strip coils slitting process, the small and large slitting machines will be used by our team. Our larger slitting machines can cut hot rolled mother coils from mill origin directly. Thickness is from 2mm to 6mm.And meantime we use the small machines to cut the narrow strip coils as precision strips. Thickness is from 0.02mm to 1.0mm.Our workers will make adjustments between coils and cutting tools when they are preparing to slit in order to minimize the burr of strips edge as much as possible.

6

Inspection Process
We have full inspection and routing inspection during metal strips mass production.Checking the stainless steel strips after they are produced carefully.The advanced inspection and measurement equipment will support every inspection process.After all end products are finished, the quality control department deal with the following inspections, such as metallographic analysis, mechanical performance testing, straightness testing, plate shape, surface finish, thickness and width tolerances inspection.

7

Packaging Process
Eye to eye or eye to wall types of packaging strips will be adopted before shipment.The surface finish of metal strips will be packaged with waterproof paper. Then coating the PVC film on this paper.After that, the banding strap will be used for fastening pallets and strips products.Before placing the metal strips into the wooden case, the strips are packaged with perfect packaging.Wooden case and four corners shall not be smaller than the outer diameter of the total strips.In addition, clear labels are tagged on the outside of these sea standard packages for easy identification of these metal strips specifications and quality information.

Factors to Consider When Selecting Stainless Steel Strip

Grade of stainless steel
Stainless steel is available in different grades, each offering different properties and characteristics. The grade of stainless steel strip you choose will depend on the application and the environment in which it will be used. For example, a highly corrosive environment may require a stainless steel strip with a higher level of corrosion resistance such as 316 or 904L grade.

Thickness and width
The thickness and width of stainless steel strip are crucial factors that determine its strength and suitability for the desired application. Thicker strips are generally more durable and have higher strength, but they may not be suitable for applications requiring flexibility. On the other hand, thinner strips offer greater flexibility but may lack the necessary strength for certain applications. Similarly, the width of the strip should be considered based on the specific requirements of the application.

Surface finish
Stainless steel strips come in different surface finishes, each serving a specific purpose. Common finishes include brushed, matte, and mirror finishes. The choice of surface finish will depend on the aesthetic requirements as well as the functionality of the strip in the intended application. For example, a mirror finish might be preferred for decorative purposes, while a brushed finish may be more suitable for applications requiring a non-reflective surface.

Tolerance and flatness
Precision and accuracy are vital in many applications where stainless steel strip is used. Therefore, it is important to consider the tolerance and flatness requirements of the strip. Tolerance refers to the permissible variation in dimensions, while flatness relates to the overall surface flatness. Assessing these factors is crucial to ensure that the stainless steel strip meets the required specifications and can be effectively utilized in its intended application.

Corrosion resistance
One of the main advantages of stainless steel strip is its resistance to corrosion. However, the level of corrosion resistance can vary depending on the grade and composition of the stainless steel. It is essential to consider the corrosive environment in which the strip will be used and select a grade with suitable corrosion resistance. In addition, factors such as the presence of chlorides, acids, or high temperatures should also be taken into account.

Cost
While cost should not be the sole determining factor, it is an important consideration when selecting stainless steel strip. The cost of stainless steel strips can vary depending on factors such as grade, finish, thickness, and width. It is important to find a balance between quality and cost-effectiveness to ensure that you are getting the best value for your money.

Cold rolled steel can exhibit strength up to 20% greater than that of hot rolled steel, which makes it more suitable for use in high-stress applications. Better surface finishes: Parts and products made from cold rolled steel generally have a smooth and shiny surface that is free of rust and scale.

Q: Is Stainless Steel Hypoallergenic?

A: Hypoallergenic metals have a low chance of causing an allergic reaction. The most common metals that cause allergic reactions are copper, zinc, and nickel. Stainless steel typically has other metals in it, including chromium or titanium. Some stainless steels have small amounts of nickel but typically not enough to cause allergic reactions. You can find nickel-free stainless steel that is 100% hypoallergenic.

Q: What is the difference between 18/8 and 18/10 stainless steel?

A: The first number is the amount of chromium that is contained in the stainless, i.e., 18 is 18% chromium. The second number is the amount of nickel, i.e., 8 stands for 8% nickel. So 18/8 means that this stainless steel contains 18% chromium and 8% nickel. 18/10 is 18% chromium and 10% nickel.
The higher the numbers the more corrosion resistant the material. Both 18/8 and 18/10 contain nickel and are part of the grade family "300 series" stainless. 18/0 means that there is 18% chromium but zero nickel. When there is no nickel the stainless grade family is the "400 series".
400 series are not as corrosion resistant as the 300 series and are magnetic, where the 300 series are non-magnetic and is the grade mainly used for sinks, Food processing equipment, Restaurant food preparation areas etc.

Q: How often should maintenance be carried out on stainless steel?

A: Maintenance on stainless steel varies due to different applications.
Interior stainless steel i.e: benches, shower trays, hand-basins, may require general cleaning on a day to day basis to maintain hygiene standards. However chemical and machine polishing processes can be carried out to remove scratches and discolouration based on personal preference. As a rule it is quite simply "clean the metal when it is dirty in order to restore its original appearance". Stainless steel can be frequently machined without causing damage.
Exterior stainless steel i.e: handrails, sculptures, down-pipes, signage, requires general cleaning to remove pollution, road grime or salt build up due to close proximity to the sea. Working environments can also create more aggressive conditions, such as the warm, high humidity atmosphere above indoor swimming pools. These environments can increase the speed of corrosion and therefore require more frequent maintenance.

Q: What To Avoid using around stainless steel?

A: Bleaches containing hypochlorite will attack stainless steel and cause pitting and staining.
Certain foods, when left for prolonged periods, can cause pitting and corrosion. Examples are citric fruit juices, salt, vinegar, mustard, pickles, and mayonnaise (even used teabags can leave hard to remove stains).
Silver dip cleaners contain acids which attack stainless steel and leave a permanent stain.
Muratic acid which is sometimes used with grout around title and stone etc.
Strong acids can damage stainless steel (i.e., photographic developing liquids or denture cleanser), if they come in contact with the stainless steel.

Q: Can stainless steel rust?

A: Stainless steel can rust. The extent of the rusting depends on the level of chromium in the alloy the more chromium, the more resistant stainless steel is to rusting. Rusting usually happens when a corrosive substance damages the chromium oxide layer that forms on the outside of stainless steel. Corrosive substances include humid air, salt water, and some cleaners and chemical liquids.
