Standard: JIS
● Features and application:
Corrosion resistance with SUS302 SUS304, because relatively high carbon intensity and therefore better. Be high strength after cold working, but inferior to the 301 steel extension. SUS302 materials for building exteriors.
● Chemical Composition: C: ≤ 0.15 Si Si: ≤ 1.00 Mn Mn: ≤ 2.00 Sulfur S: ≤ 0.030 P P: ≤ 0.035 Chromium Cr: 17.00 ~ 19.00 Nickel Ni: 8.00 ~ 10.00
● Mechanical Properties: Tensile strength σb (MPa): ≥ 520 Chongqing, Hangzhou, provided (a) conditions yield strength σ0.2 (MPa): ≥ 205 Elongation δ5 (%): ≥ 40 Reduction of area ψ (% ): ≥ 60 hardness: ≤ 187HB; ≤ 90HRB; ≤ 200HV
● Heat treatment and microstructure specifications: standard heat treatment: solution 1010 ~ 1150 ℃ fast-cooling. Microstructure: Organizing for the austenitic type.
