2. Forged condition, annealing or harden,  milled surface

3.Pre-heat treatment:

• Annealing : heat to 840-860°c, keep 2H, furnace cold, hardness≤217HBS
• High temperature tempering : heat to 680-700°c, air cold, hardness ≤217HBS

4.Heat treatment: 

•  Normalization: heating to 840 to 880 °C, maintenance, furnace cooling to 600 °C, then in air.
•  Stress relieving: after rough heat to 500 °C, maintenance raff. In oven to 400 °C, then in air.
• Hardening: preheating from 600 to 650 °C austenitizing at 840 to 880 °C, quenching in oil. 
• Tempering: heating to 550 - 650 °C and maintenance regime, again depending on the mechanical properties 

5. Forged technology: EAF+LF+VD+ESR+Forging +Q T + Machined surface 

6. Ultrasonic test standard: SPE1921-GR3, CLASS C/C or D/D

7. Production leadtime: 7~10 days

8. Chemical composition:

C	Mn	Si	Cr	Ni	Cu	P	S
0.17-0.23	0.30-0.60	0.15-0.40	1.25-1.75	3.25-3.75	≤0.25	≤0.030	≤0.030
