ASTM A387 steel is the standard specification for pressure vessel plates, alloy steel, chromium-molybdenum. Plates under this standard Hebei Metals supplies include ASTM A387 Grades 2, P235GH steel pipe Grade 12, Grade 11, Grade 22, Grade 22L, Grade 21, Grade 21L, Grade 5, Grade 9, Grade 91. Each grade except Grades 21L, 22L, and 91 is available in two classes of tensile strength levels. These Cr-Mo A387 alloy steel is primarily manufactured for welded boilers and pressure vessels for elevated temperature service.

Grades p235gh steel pipe, Q345 (16Mn) and Q390 steel have good comprehensive mechanical properties, good welding performance, cold and hot workability and corrosion resistance. C, D, E grade steel has good low temperature toughness. Mainly used for ships, boilers, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welding structural parts.

Quenching Improve the hardness of p235gh steel pipe steel, Annealing is refine the grain size, homogenization, reduce hardness, improve the plasticity and eliminate interna stress. Normalizing refine grain , improve the impact toughness of p235gh steel pipe steel and comprehensive mechanical properties.
