Composition and properties of SA516Gr65(HIC), SA516 Gr65(R-HIC) steel sheet

Smelting analysis of chemical composition of SA516Gr65(HIC) steel sheet:
C≤0.29; Mn: 0.85-1.2; P≤0.035; S≤0.035; Si: 0.15-0.4.
Note: The specifics are subject to the actual

SA516 Gr65(R-HIC) steel sheet chemical composition smelting analysis:
C ≤ 0.26; Si: 0.15 - 0.4; Mn: 0.85 - 1.2; P ≤ 0.015; s≤0.003; Ni ≤ 0.3; Cr ≤ 0.3 m; ≤0.08; Cu≤0.3; Alt≥0.02; Ceq Max≤0.43.
Remarks for composition: Cr+Ni+Mo+Cu≤0.7; V+Ti+Nb≤0.05; Als can be used instead of Alt, at this time Als≥0.015; if V, Ti, Nb and other trace elements are added to the steel, the lower limit of Al content is not limited. Ceq = C+Mn/6+(Cr+Mo+V)/5+(Ni+Cu)/15
