The thickness of 304 stainless steel is 0.3mm, 0.4mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm. 0.9mm, 1.0mm, 1.2mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 4-100, etc. Many thickness specifications of stainless steel 304.

304 is a versatile stainless steel that is widely used to make equipment and parts that require good comprehensive properties (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a brand of stainless steel produced in accordance with American ASTM standards.

304 stainless steel processing method

1. Etching method

The etching method uses wire on the surface of stainless steel. The acid-resistant protective film is screen-printed and then etched with ferrous chloride liquid to form an artistic pattern.

2. Inkjet color method

The inkjet color method is to spray color particles after screen printing to form a pear skin-like surface and form an artistic pattern.

3. Process

The process of spray color art processing of stainless steel products is: stainless steel products → silk screen → etching → alkali treatment → silk screen → oxidation coloring → alkali treatment → finished product . The process of etching art processing of stainless steel products is: stainless steel products → silk screen → etching → alkali treatment → oxidation coloring → finished product.

4. Stamping processing

For stainless steel products, especially stainless steel strips, many times the original processing method in factories is to use a punch machine to stamp products. Stamping includes two methods: straight punching and stretching. Generally, stretching and bending are used when the hardness is lower than 1/2, and straight punching is used when the hardness is higher than 1/2.
