Physical properties of 20MnV steel plate:
The 20MnV steel plate tensile strength is 785MPa, the yield strength is 590MPa, the elongation after fracture is 10%, the reduction of area is 40%, and the impact absorption energy is 55J.
20MnV steel plate has good properties, good strength, toughness and plasticity, good hardenability and machinability. After carburizing, 20MnV steel plate can be directly quenched without secondary quenching to improve the core structure. The weldability of 20MnV steel plate is good, but there is temper brittleness at 300-360℃ during heat treatment.
Just like you, 70% customers choose long-term cooperation with BBN steel not only for our good product and service quality, good reputation in the international market, but also for our experienced one-stop raw material supply and further steel processing!
