40Cr Alloy steel round bar Impact energy

40Cr Alloy steel round bar machinery manufacturing industry is one of the most widely used steel.In addition to outside 40Cr Alloy steel round bar quenching is further adapted to cyanide and high quenching. Cutting performance is better, when the hardness of 174 ~ 229HB, the relative machinability of 60%. 40Cr Alloy steel round bar suitable for the production of medium-sized plastic molds.
