Chemical composition of SA302GrC steel (melting profile%)
SA302GrC plate has different element content requirement in different thickness as follows:
Thickness less than 25mm
C: ≤0.20, Mn: 1.15-1.50, P: ≤0.025, S: ≤0.025, Si: 0.15-0.40, Mo: 0.45-0.60, Ni: 0.40-0.70
Thickness ranges 25 to 50mm
C: ≤0.23, Mn: 1.15-1.50, P: ≤0.025, S: ≤0.025, Si: 0.15-0.40, Mo: 0.45-0.60, Ni: 0.40-0.70
Thickness over 50mm
C: ≤0.25, Mn: 1.15-1.50, P: ≤0.025, S: ≤0.025, Si: 0.15-0.40, Mo: 0.45-0.60, Ni: 0.40-0.70
