40cr is China's GB standard steel, 40Cr steel is one of the most widely used steel in the machinery manufacturing industry. After tempering and tempering treatment, it has good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. Of 40Cr steel hardenability is good, when water quench hardening to Ф 28 ~ 60 mm, when oil quenching hardening to Ф 15 ~ 40 mm. In addition to quenching and tempering, this 40Cr steel plate is also suitable for cyaniding and high-frequency quenching. When the hardness is 174 ~ 229HB, the relative machinability is 60%. 40Cr steel plate is suitable for making medium sized plastic moulds.
