DIN 1.2767/X45NiCrMo4 STEEL FORGING

• Initial Forging Temperature:1100-1200ºC
• Final Forging Temperature:800-900ºC
• Forging Ratio:above 4:1
• Cooling Method After Forged:As high nickel tool steel,DIN 1.2767 steel should be annealed after forging.

DIN 1.2767/X45NiCrMo4 STEEL HEAT TREATMENT

• DIN 1.2767/X45NiCrMo4 Isothermal Annealing

Firstly, DIN1.2767 steel is heated to the austenitization temperature of 860°C and held for 1 hour, then cooled to 640°C at 30°C/h, held for the corresponding time, and finally cooled to room temperature with the furnace.

Generally speaking, as the isothermal time prolongs, the hardness will gradually decrease.The annealed hardness of DIN 1.2767 steel is usually below 262HB.

DIN 1.2767/X45NiCrMo4 Quenching & Tempering

Quenching Temperature:840-870ºC

Quenching Medium:oil

Tempering should be followed after quenched.Tempering twice is recommended.
