JIS G4304 SUS430 2B Stainless steel

What is JIS G4304 SUS430 2B Stainless?
JIS stainless steel grades are denoted as SUS followed by a number (e.g., SUS304, SUS316, SUS430)

  1. JIS G4304 SUS430 2B: This standard pertains to hot-rolled stainless steel plates, sheets, and coils. It covers a range of stainless steel grades, specifying requirements for chemical composition, mechanical properties, and surface finishes.
  2. SUS430 2B: SUS430 is a ferritic stainless steel known for its good corrosion resistance and formability, mainly containing chromium and lacking nickel, which is a typical component in austenitic stainless steels.

3.Here’s a general summary table for SUS430 2Bstainless steel coils as per the JIS G4304 standard:

4. Applications: SUS430 2B coils are commonly used in kitchen utensils, automotive trim, interior architectural elements, and various appliances.

Please consult the specific manufacturer or material data sheets for precise information, especially if the term “SUS4302B” refers to a specialized or proprietary grade.

5. If “4302B” was meant to indicate a specific finish or processing method, it’s not a standard designation I’m familiar with. However, stainless steel coils can indeed come in various finishes, like 2B, which is a standard mill finish that is smooth and reflective, though not as reflective as a BA (Bright Annealed) finish.
