ASTM A242 has 2 grades: Type 1 and Type 2, while type 1 is the most used structural steel grade. Usually GL-DH 40 oil platform engineering steel it is produced to be hot rolled state, it is suitable for cutting, forming, drilling and machining, grinding.
High wear resistance: fully automatic CNC stacking equipment, independent of manual GL-DH 40 oil platform engineering steel welding technology, produces fully qualified high-quality products. Special automatic welding technology enables the chromium content of wear-resistant layer to be controlled at more than 28%, and the GL-DH 40 oil platform engineering steel hardness is between 58-62, which fully ensures that our wear-resistant layer has continuous good and balanced wear resistance. The wear test in metallurgy, cement and other industries shows that the wear resistance of the wear-resistant layer of the surfacing composite GL-DH 40 oil platform engineering steel wear-resistant steel plate is more than 30 times that of the 16Mn plate with the same thickness.
Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the GL-DH 40 oil platform engineering steel quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After GL-DH 40 oil platform engineering steel quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.
