The temperature of critical points Ac 1 = 780, Ac 3 (Ac m) = 795, Ar 3 (Arc m) = 695, Ar 1 = 675, Mn = 280. Hardness after annealing (GOST 5950−2000): HB 10 -1 = 217 MPa.
complex shape punches cold EEPROM advantageously shaped holes in a sheet and strip material, small hot forging dies, especially when the sizes required minimum change in quenching.
