Material type deep processing, that is, the product after deep processing still belongs to the nature of raw materials, this kind of en standard P235GH steel deep processing has been widely developed, so it is called the traditional deep processing of steel.Broad sense, in the production of steel products to pass through the cold hot working wood timber are belong to the type material deep processing, such as manufacture, paint coating plate, cold bending steel, en standard p235gh steel welded steel pipe, welding steel cold drawn section steel, steel rods, silver steel rods, wire products (cold drawn steel wire, steel hinge line, cord, piano wire, steel wire, cold heading steel wire) and other all belong to such.

SA387Gr91 delivery status: normalized + temperedSA387Gr91 specification: 6mm-250mmThe mechanical properties of SA387Gr91: tensile strength: not less than 585SA387Gr91 yield strength: not less than 415SA387Gr91 elongation: not less than 20en standard p235gh steel, SA387Gr91CL2 steel is used to make equipment such as coal gasifier, shift furnace, and hydrogenation reactor.

Annealing of en standard p235gh steel steel plate, the steel is heated to a certain temperature and kept warm for a period of time, and then let it slowly cool, called annealing.Annealing of steel is a heat treatment method in which the steel is heated to the temperature of phase change or partial phase change and cooled slowly after heat preservation.The purpose of annealing is to eliminate the microstructure defects, improve the microstructure, make the composition homogenization and refine the grain, improve the mechanical properties of en standard p235gh steel steel, reduce the residual stress.

Product concept: take the technology leading as the pillar of the enterprise, achieve the development goal of the enterprise with the reliable products, the reliable technology and the trustworthy services, and devote to the creative reform activities leading in the technical development and career of the industry to create new value through continuous change.
