Following is heat treatment way of 1.4922 ,X20CrMoV11-1,X20CrMoV12-1 ,X20CrMoNV11-1-1 steel pipes
Soft Annealing of X20CrMoV11-1 forging rings
Heat to 730-780c, cool slowly in furnace or air.
Stress Relieving of X20CrMoNV11-1-1 forged tubes
Stress relieving to remove machining stresses should be carried out by heating to 650-6809c,holding for one hour at heat, followed by air cooling. This operation is performed to reducedistortion during heat treatment.
Hardening of X20CrMoV12-1 forging sleeves
Harden from a temperature of 1020-10709c followed by air or oil quenching. Structure ismartensite.
Tempering of X20CrMoV11-1 forging round bars
Tempering temperature: 720-7809c.
Mechanical properties of steel 1.4922 ,X20CrMoV11-1,X20CrMoV12-1 ,X20CrMoNV11-1-1 Forging steel pipes sleeves is as follows
Rm - Tensile strength (MPa) (+NT) 690-840
