The advantages of using stainless steel for sheet metal fabrication are numerous. The material's tensile strength, resistance to corrosion, and shinny appearance make it ideal for various applications. Products ranging from airplanes to subway trains have used stainless steel components.

Types of Stainless Steel Sheet
 

Ferritic stainless steel
With a similar structure to low alloy steels, ferritic stainless steel boasts strong resistance to corrosion cracking. Containing little to no nickel, it is a cost-effective stainless steel that typically has a significant percentage of chromium (11.2% - 19%).

 

Austenitic stainless steel
Austenitic stainless steel is the most common variety of stainless steel, making up more than 70% of overall production. It’s a well-rounded stainless steel, with adequate weldability, formability, and creep resistance.Unlike ferritic steel, austenitic varieties are for all intents and purposes non-magnetic.When you add a large proportion of molybdenum (over 6%), the steel becomes super austenitic, which gives it better protection against crevice corrosion and cracking.

 

Martensitic stainless steel
Martensitic stainless steel contains chromium, nickel, molybdenum, and carbon, which makes for a more brittle microstructure. Martensitic stainless steel is generally tougher than the austenitic and ferritic varieties.Though they have relatively low formability, these alloys can be tempered as you would with carbon steels.

 

Duplex stainless steel
These hybrid alloys are called duplex because the composition is about 50% austenitic and 50% ferritic. By combining the two microstructures, you end up with a new form that has more strength than both.The strong composition also leads to improved corrosion resistance and stress cracking resistance.

 

Precipitation hardened stainless steel
This martensitic stainless steel type has been made even stronger by adding aluminum, copper, and niobium, in conjunction with a precipitation hardening process. It involves heat-treating the metal to create particles in the crystal lattice, which help to stop irregularities in the microstructure and boost the alloy’s overall strength.

 

Material of Stainless Steel Sheet

Stainless steel

Stainless steel sheet is typically made of austenitic stainless steel, which contains high levels of chromium and nickel. This makes the material resistant to corrosion, heat, and wear. The specific alloy used for the sheet can vary depending on the intended application, with different grades offering different levels of hardness, strength, and chemical resistance. Some common grades of stainless steel sheet include 304, 316, and 430.

How should stainless steel sheets be stored?

Step 1

First and foremost, it is important to ensure that the storage area is clean, dry, and free from any contaminants. Stainless steel is susceptible to corrosion, especially when exposed to moisture or other corrosive elements. Therefore, the storage space should be well-ventilated and have a controlled temperature and humidity level.

 

Step 2

To prevent any scratching or damage, stainless steel sheets should be stored in a way that minimizes the risk of contact with other materials. Ideally, they should be placed in a vertical position, with each sheet separated by a suitable material such as wooden boards or plastic sheets. This prevents any direct contact between the sheets, reducing the possibility of scratches or other surface imperfections.

Step 3

Proper labeling and organization are essential for efficient storage. Each sheet should be clearly labeled with relevant information such as dimensions, grade, and quantity. This not only facilitates easy identification but also prevents any confusion or mix-up during retrieval. Additionally, organizing the sheets according to size or grade can save time and effort when searching for a specific sheet.

Step 4

It is advisable to handle stainless steel sheets with care during storage. Rough handling or dropping the sheets can cause deformation or surface damage. Therefore, using appropriate lifting equipment, such as overhead cranes or forklifts, is recommended to safely move and store the sheets.

Step 5

Regular inspection and maintenance of the storage area are also essential to prevent any potential issues. Inspecting for any signs of corrosion, leaks, or other damages on a routine basis can help identify and address problems at an early stage. Additionally, keeping the storage area clean and removing any accumulated debris or moisture can prevent the onset or spread of corrosion.

What to avoid with Stainless Steel Sheet?
 
1

Avoid using acidic or chloride-containing cleaners
Acidic or chloride-containing cleaning agents can cause pitting corrosion on stainless steel surfaces. It is advisable to use mild, non-abrasive cleaners, specifically designed for stainless steel, to prevent any damage or discoloration.

2

Avoid using rough or abrasive materials
When cleaning or maintaining stainless steel sheets, avoid using rough scouring pads, abrasive powders, or steel wool. These materials can scratch the surface, leading to potential corrosion sites and compromising the aesthetics of the sheet.

3

Avoid prolonged exposure to saltwater or high-chloride environments
Stainless steel sheets are highly resistant to corrosion, but prolonged exposure to saltwater or high-chloride environments can still cause corrosion over time. Therefore, it is essential to regularly rinse off any salt residue and properly dry the sheets to minimize the risk of corrosion.

4

Avoid contact with other metals
Direct contact between stainless steel sheets and other metals, especially those with lower nobility, can result in galvanic corrosion. This occurs when two dissimilar metals come into contact, creating an electrochemical reaction that can degrade the stainless steel. To prevent galvanic corrosion, ensure that stainless steel sheets are not in contact with metals like aluminum, carbon steel, or copper.

5

Avoid rough handling or impact
Stainless steel sheets may be durable, but they can still be vulnerable to damage from rough handling or high impact. Avoid dropping heavy objects or subjecting the sheets to excessive force, as this can cause dents, scratches, or deformations, compromising their structural integrity.

6

Avoid prolonged exposure to high temperatures
While stainless steel has good heat resistance, prolonged exposure to high temperatures can impact its structural and aesthetic properties. It is important to avoid placing hot pans, pots, or objects directly on the stainless steel sheet surface, as this can cause discoloration or even warping.

7

Avoid improper installation or fabrication techniques
When installing or fabricating stainless steel sheets, it is crucial to follow proper techniques and guidelines. Avoid using improper fastening methods or excessive heat during welding, as these can weaken the stainless steel and potentially lead to failure or deformation.
