Grade	SS302/12Cr18Ni9
Chemical Composition(%)	C: ≤0.15 Mn: ≤2.00 Si: ≤1.00 P: ≤0.035 S: ≤0.030 Ni: ≤8.00-10.00 Cr: ≤17.00-19.00
Mechanical Property	Yield Strength(MPa): ≥205 Tensile Sstrength(MPa): ≥520 Elongation(%): ≥40 Hardness(Hv): ≤92

Hardening Type 302 can be hardened only by cold working. Annealing Heat in the range of 1850-2050°F and cool rapidly. Light gauges (under 16 gauge) may be air cooled. Heavier sections require water quenching from annealing temperature. Stress Relieving The recommended temperature range for stress relieving is 400-750°F.
