4.Heat treatment 

1.Quench:1000-1040`C via 600`C and 850`C, preheating oil or wind cooling

2.Temper temperature should be higher than working temperature in order to stabilize the working size of mold

3.Heat up to 650°C of average temperature in order to eliminate the machined stress, 500  °c air cooling after electric cooker cooling

4.Tempering, 800-850  °c ,slow cooling after diathermia

5. Melting Process of SKD61 steel rod 

1.EAF: Electric Furnace+LF+VD(Optional)

2.ESR:  Electric Furnace+LF+VD+Eleroslag Remelted(Optional)

UT Class of SKD61 steel rod

5.Characteristic of H13 steel
