JIS G4304/4312 SUS 201 is a nickel steel, which is austenitic stainless steel. Its chemical composition mainly includes chromium, nickel, manganese and nitrogen and other elements, and it is an alternative to 301 stainless steel. The material has excellent formability and corrosion resistance, and is often used to make a variety of parts and equipment requiring corrosion resistance and formability.
Features of JIS G4304/4312 SUS 201 Stainless steel:
Corrosion resistance: JIS G4304/4312 SUS 201 has excellent corrosion resistance due to a certain amount of chromium and nickel, maintaining its stability and service life in a variety of environments.
Formability: The material has good formability, suitable for cold and hot processing, and can meet the complex forming needs.
Strength and toughness: JIS G4304/4312 SUS 201 has the appropriate strength and toughness to meet the requirements of general structural parts.
The main chemical components of JIS G4304/4312 SUS 201 are as follows:
The maximum carbon (C) content is 0.15%
The maximum silicon (Si) content is 1.00%
The content of manganese (Mn) is between 5.5% and 7.5%
The maximum phosphorus (P) content was 0.060%
The maximum sulfur (S) content is 0.030%
Nickel (Ni) content is between 3.5% and 5.5%
The chromium (Cr) content is between 16% and 18%
Nitrogen (N) content is up to 0.25%
JIS G4304/4312 SUS 201 is usually delivered in hot or cold rolled condition and may also require annealing, pickling or other surface treatment depending on the specific production standards and customer requirements.
JIS G4304/4312 SUS 201 is widely used in many fields such as automobiles, home appliances, kitchenware, construction and chemical industry due to its excellent corrosion resistance and formability. For example, it can be used to make automobile exhaust pipes, kitchen utensils, building materials, etc., to meet the high requirements for corrosion resistance and formability of materials in these fields.
