American standard SA387 Gr12 Cl2 steel chemical composition and delivery status

SA387 Gr12 Cl2 steel is an American standard pressure vessel steel plate. SA387 Gr12 Cl2 steel has the ability to prevent hydrogen embrittlement, hydrogen corrosion, hydrogen stripping, and sulfide corrosion in a medium temperature (350-480) hydrogen environment, and has good performance. SA387 Gr12 Cl2 pressure vessel steel plate has low temper brittleness and is widely used in the manufacture of fertilizers, petrochemicals and thermal power plant equipment, such as synthetic ammonia reactors, coal gasifiers, shift furnaces and hydrogenation reactors. Using special smelting methods to reduce the content of phosphorus so that SA387MGr.12cl.2 has high brittleness resistance, and also has good impact toughness in low temperature environment.

The size, shape, weight and allowable deviation of SA387 Gr12 Cl2 steel plate shall comply with the regulations of ASME SA387/SA387M standard.

Delivery status and specifications of SA387 Gr12 Cl2 steel plate:
SA387 Gr12 Cl2 material is suitable for refining and gas treatment in hydrogenation reaction and conversion equipment at high temperature, and the maximum thickness of SA387 Gr12 Cl2 steel plate can reach 250mm thickness. According to different thickness and impact requirements, the delivery status of SA387 Gr12 Cl2 steel plate is: normalizing plus tempering or normalizing plus rapid cooling plus tempering.

Application scope of SA387 Gr12 Cl2 steel:
SA387 Gr12 Cl2 steel is used in petroleum, chemical, power station, boiler and other enterprises, and is widely used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear reactor pressure shells, boiler drums, liquefied petroleum gas cylinders, high-pressure water pipes of hydropower stations, turbine volutes and other equipment and engineering components.
