(2): The allowable deviation of the chemical composition of the finished steel plate shall comply with the provisions of
GB/T222 SA387Gr91CL2 mechanical properties:
tensile strength≥ 585MPa yield strength≥ 415MPa elongation≥ 20%
SA387Gr91CL2 delivery status:
SA387Gr91CL2 American Standard Container Board, Wugang Ministry of Science and Technology Container Grade, SA387Gr91CL2 uses special smelting methods to reduce the content of phosphorus, so that SA387Gr91CL2 has high brittle resistance, and at the same time has the best impact toughness in low temperature environment. According to different thickness and impact requirements, the heat treatment of SA387Gr91CL2 steel plate can be normalized plus tempered or normalized plus rapid cooling plus tempering. SA387Gr91CL2 steel plate Wugang futures fixed rolling, fast delivery, mature Wugang production technology, excellent steel plate quality, internal flaw detection strong
Application range:
SA387Gr91Cl2 is widely used in the manufacture of chemical fertilizers, petrochemical and thermal power plant equipment, such as synthetic ammonia reactors, coal gasifiers, conversion furnaces and hydrogenation reactors, etc., can be used as subcritical and supercritical boiler wall temperature ≤ 625 high-temperature superheater, reheater steel pipe, As well as wall temperature ≤ 600 high-temperature header and steam pipeline, it can also be used as a nuclear power heat exchanger as well as oil projects
