Research of Hot Ductility for ML40Cr with Cold Forging Steel
Hot ductility of ML40Cr steel at the temperatures from 700°C to 1300°C was measured on simulator Gleeble-1500. The results are as follows: the hot ductility reduces in temperature range of 950°C to 1300°C, and increases in temperature range of 700°C to 950°C. The reduction of cross section area is reduced obvious in temperature range of 950°C to 1300°C, and Extensibility fall is slow. The best hot ductility of ML40Cr steel is 950°C.
