What is the ASTM A387 GR 11 equivalent to?

What is the ASTM A387 GR 11 equivalent to?
Sa 387 Gr 11 Equivalent Material is the ASME SA387 in the US markets with the European Union having modules in 13CrMoSi5-5 grade. The Sa 387 Gr 11 Cl 2 Equivalent Material is the SA387-11-2 of the ASME and ASTM standard.

What is the chemical composition of ASTM A387 Grade 12?
ASTM A387 GR 12 CL 2 Plates is designed with chemical components such as silicon, chromium, vanadium, molybdenum, sulfur, phosphorus, carbon, and manganese. Alloy Gr 12 has some tensile requirements, such as tensile strength, area reduction, elongation, and yield strength.

What is the difference between SA 516 GR 70 and SA 387 GR 11?
While SA 516 Gr 70 plates have good tensile strength, they do not possess the same corrosion and oxidation resistance level as SA 387 Gr 11 plates. SA 516 Gr 70 plates are also susceptible to brittle fracture at low temperatures, making them unsuitable for cryogenic applications.
