A387 Grade 12 CL 1,A387 Grade 12 CL 2 are under steel specification standard ASTM A387/A387M for pressure vessel steel plates,alloy steel with Chromium-Molybdenum.The equal steel plate SA387 Grade 12 CL 1 and SA387 Grade 12 CL 2 are under American steel standard SA 387/SA 387M.All these alloy steel plates intended primarily for welded boilers and pressure vessels&tanks.Rolling maximum thickness of plates is limited only by the capacity of the composition to meet the specified mechanical property requirements.
A387Gr12CL1 pressure vessel steel plate owned minimum yield strength at 275 Mpa,and tensile strength within 450-585 Mpa.Pressure vessel steel plate SA387 Grade 12 CL 1 is in American standard ASME SA 387/SA 387M.Boiler steel plate A387 Grade 12 Cl 1 are according to ASTM A387/A387M.
These steel materials also shall conform to steel specification A 20/A 20M.These requirements outline the testing and retesting methods and procedures,permissible variations in dimensions and weight,quality and repair of defects,marking,loading,etc.
