A387Gr22CL2 boiler steel plate is under steel standard specification ASTM A 387/A 387M for pressure vessel steel plates with alloy Cr. And Mo.Pressure vessel steel plate A387 Grade 22 CL2 is mainly intend for welded boilers and pressure vessels designed for elevated temperature services.When rolling boiler plate A387Gr22cl2 other steel standard shall be followed,A20/A20M,A370 test methods and definitions for mechanical testing of steel products, A435/A435M, A577/A577M and A588/A588M.
a387 grade 22 class 2 steel is characterised by good weldability, it effective working temperature up to 600°C.
a387 grade 22 class 2 steel is 2.25% chromium – 1% Molybdenum, these Chromium and Molybdenum pressure vessel steel plates can effectively works very well in elevated temperatures with minimum aging of the product after thousands of hours of work.
