For pressure vessel steel plate SA387 Grade 12 CL 1,the tensile strength shall be within 380 to 550,minimum yield strength is 230 Mpa.For SA387 Grade 12 CL 2 pressure vessel steel plate,the tensile strength is at 450-585 Mpa and yield point shall be above 275 Mpa.Besides the five main elements, Cr-Mo is also in the chemical composition for these alloy steels.
Engineered for use in elevated temperature service, ASME SA387 Grade 12 is a chrome molybdenum carbon alloy steel for use in weldable pressure vessels and industrial boilers.
The material benefits from added chromium which provides excellent corrosion and oxidation resistance making it ideal for sour service applications in the oil and gas industry.
