40Cr steel technology and specifications

40Cr steel mechanical steel manufacturing one of the most widely used. After quenching with good mechanical properties, good low temperature impact toughness and low notch sensitivity. Good hardenability of steel, water-quenching hardenability to Ф28 ~ 60mm, when oil quenching hardenability to Ф15 ~ 40mm. This steel is quenched things, except for cyanide and high frequency quenching. Cutting preferably, when the hardness of HB174 ~ 229, the relative machinability of 60%. The steel is suitable for production of medium-sized plastic molds.
