JIS G4305 SUS302B is a type of cold-rolled stainless steel sheet that is widely recognized for its excellent corrosion resistance and high-temperature strength. This grade is specified by the Japanese Industrial Standard (JIS) and is commonly used in various industries due to its balanced chemical composition and mechanical properties.

Chemical Composition:

The chemical composition of SUS302B is carefully controlled to ensure its performance and durability. The typical chemical composition includes:

· Carbon (C): 0.15% max

· Silicon (Si): 1.00% max

· Manganese (Mn): 2.00% max

· Phosphorus (P): 0.045% max

· Sulfur (S): 0.030% max

· Nickel (Ni): 8.00-10.00%

· Chromium (Cr): 17.00-19.00%

· Nitrogen (N): 0.10% max

Mechanical Properties:

The mechanical properties of SUS302B are as follows:

· Tensile Strength (MPa): 520

· Yield Strength (MPa): 205

· Elongation (%): 40
