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 H12steel 

(1) High strength toughness, high chromium steel

(2) Good hot intensity and rigidity.

(3) Good tenacity, hot tirdness nature and wearable in medium temperature

(4) Empty quench in low Austenitizing temperature condition, little distortion after heat treatment.

6.Application  

(1) Used in hard plastic mold , aluminum, zinc alloy die-casting mold , forging hammer.

(2) high  speed precision forging die insertsdrawing dies, plate dies and edge or cold shears,etc.

(3) All products' technology request and dimensions
