YF45MnV Free Cutting Steel Bar
YF45MnV is for 40Cr, 35CrMo, 42CrMo and other quenched and tempered steel developed sulfur-free cutting steel, is a non-quenched and tempered non-quenched and tempered steel. Widely used in automotive rod, tractor crankshaft, engineering machinery transmission screw, front axle rod, rack shaft. YF45MnV steel chemical composition, mechanical properties, non-metallic inclusions, low magnification, grain size must meet the Chinese standard GB / T15712 technical requirements.
Due to the fact that China's previously produced automobiles, tractors, motorcycles, construction machinery, agricultural machinery and other industries have historically used parts made of quenched and tempered steel (45, 40Cr, 35CrMo, 42CrMo), etc. Since quenched and tempered steel needs to be quenched and tempered, Consumption of energy, can cause oxidation, decarburization, deformation, cracking and other shortcomings. Therefore, people have been committed to the development of non-quenched and tempered non-quenched and tempered steel.
