SA387MGr12Cl2 is a steel plate for American standard pressure vessels

SA387MGr.12 Cl.2 is an American standard container board, belonging to the Container Institute of the Technical Department of Wuyang Steel Plant, SA387MGr.12 Cl.2 has the ability to prevent hydrogen embrittlement, hydrogen corrosion, hydrogen stripping, sulfide corrosion in the medium temperature (350 ~ 480) hydrogen environment, and has good low temper brittleness, and is widely used in the manufacture of chemical fertilizers, petrochemical industries and thermal power plant equipment, such as synthetic ammonia reactors, coal gasifiers, transformation furnaces and hydrogenation reactors. SA387MGr.12cl.2 has high brittle resistance and good impact toughness at low temperature by reducing the phosphorus content by using special smelting methods.
