SUS302 Standard: JIS 

 ● Features and Scope: SUS302 corrosion resistance with SUS304, because relatively high carbon intensity and therefore better. Be high strength after cold working, but extends inferior to 301 steel. SUS302 for the exterior of the building decoration materials. ● Chemical Composition: C: ≤ 0.15 Si Si: ≤ 1.00 Manganese Mn: ≤ 2.00 S S: ≤ 0.030 P P: ≤ 0.035 Cr-Cr: 17.00 ~ 19.00 Ni-Ni: 8.00 ~ 10.00 ● Mechanical Properties: Tensile strength σb ( MPa): ≥ 520
