45# steel is high-quality carbon structural steel with low hardness and easy cutting. After quenching and tempering, the parts have good comprehensive mechanical properties. 45# steel is widely used in motorcycles and automobiles, especially those connecting rods, bolts, gears and shafts that work under alternating loads, huge friction, usually quenching method to improve its own hardness, wear resistance and service life.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the S690QL steel hardness steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.
