Normalizing temperature of what is Q355GNH steel

The weight of seamless steel pipe is only 1 / 5 of that of square steel. Seamless steel pipe corrosion resistance acid, alkali, salt and atmospheric environment corrosion, high temperature resistance, good impact and fatigue resistance, do not need regular maintenance. The effective service life of product what is Q355GNH steel more than 15 years.

The pre cooling direct quenching and low temperature tempering of wear-resistant composite plate can reduce the quenching deformation of the workpiece, and the residual austenite content in the carburized layer can also be slightly reduced. The surface hardness of the hardfacing wear-resistant composite plate, what is Q355GNH steel is slightly increased, but the austenite grain does not change. It is widely used in various tools of fine grain steel manufacturing.
