25Cr2MoVA Hardware Tool Steel Bar


25Cr2MoVA is carbon heat-resistant steel. Strength and toughness are high. Below 500 ℃, the high temperature performance is good, no tendency to hot embrittlement, hardenability is good, machinability is acceptable, cold deformation plasticity, poor weldability. Generally can be used in the state of quenched and tempered, but also can be used after normalizing and high temperature tempering. For the manufacture of high temperature nuts (less than or equal to 550 ℃), bolts, studs (less than 530 ℃), long-term operating temperature to 510 ℃ fasteners, steam turbine rotor, sleeve, main steam valve, , But also as nitriding steel, used to make stem, gear and so on.
