a516 grade 70 equivalent H beams

A572 gr42 steel plate is a kind of main precision steel structure and normalizing steel. a516 grade 70 equivalent, ASTM A572 gr42, 50, 55, 60, 65 is a kind of high strength low alloy steel plate, which is widely used in factory construction, general buildings and various construction machinery, such as mining and various construction drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, hydraulic supports, mining machinery and other structures.

Our company has a516 grade 70 equivalent strong technical force, complete production equipment, advanced production technology, perfect testing methods, and high quality. It has a Class D (Class I and Class II pressure vessel) manufacturing license, and has passed the China Beijing Quality Center GB/T19001-2000 -ISO9001: 2000 quality certification. We can also supply a516 grade 70 equivalent deep processing service for products a516 grade 70 equivalent like cutting, drilling, bending, welding and grinding.

Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium a516 grade 70 equivalent carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some a516 grade 70 equivalent alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.

Temperature has a great influence on the strength of the material, a516 grade 70 equivalent. When the temperature exceeds a certain value, the strength limit of the steel will be reduced. The higher the temperature, the lower the strength. In addition, the longer the steel is used at high temperature, the lower the strength. Therefore, if the steel works at high temperature for a long time, the instantaneous strength of the steel can not be used as its performance index, nor can the room temperature performance replace the high temperature performance.
