3.Characteristic of steel plate H13
 

Harden   and air cooling steel, 600`C work, high rigidity, high endurance,   anti-heating, anti-cracking, electric sediment and middle-melting steel,   compact structure, refined in electric cooker, quality of steel is pure,   owned good character of equal direction.

4.Application of steel plate H13
 

1. Extrusion mold of aluminum and magnesium,   die-casting mold, especially adapt to the mold in large and complicated form.

2.   Extrusion mold of copper alloy, die-casting mold,pressing mold,plastic thin   wall mold

3.   Hot pressing machine mold

5.Heat Treatment of steel plate H13

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

2.Temper temperature and rigidity   HBC(reference):  

 quench   hardening

 108-300 °c

450-500 °c

550-5700°c

53-55   

    51-52

 53-54   

 50-52

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

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

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

6.Melting Process of SKD61 steel rod 

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

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

7.UT Class of SKD61 steel rod

According to Standard of SEP 1921/84,100%   Volume, Level C/c, D/d or E/e
