The inventory status and trend of grade p235gh steel material

Low alloy high strength structural steel is a kind of steel which contains a small amount of alloy elements and is mainly used in construction and engineering structures. Main Chinese steel grades of low alloy high strength structural steel are: Q345A, Q345B, Q345C, Q345D, Q345E, Q390A, Q390B, Q390C, Q390D, Q390E, Q420A, Q420B, Q420C, Q420D, Q420E, Q460C, Q460E, Q500C, Q500D, Q500E, Q550C, Q550D, Q500D, Q620E, Q690C, Q690E, grade P235GH steel material.

Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, grade p235gh steel material.

Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter grade p235gh steel material steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.

The company conducts periodic and targeted training and guidance for after-sales service personnel. As the saying goes, "no one is perfect, no gold is red", to help after-sales service personnel improve service skills and correct service attitude. Carry out relevant technical training for after-sales service personnel, so that after-sales service practitioners have professional product knowledge.
