Specially: Harden and air cooling steel, 600°C work, high rigidly, 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.

Use: Extrusion mold of aluminum and magnesium, die-casting mold, especially adapt to the mold in large and complicated form. Extrusion mold of copper alloy, die-casting mold, hot pressing machine mold.

Heat treatment:

Quench :1020-1050°C, oil cooling or air cooling,HRC56-58.

Tempering : tempering temperature should be higher than mold work temperature so that the mold scale is stable to eliminate stress, it can use 650°C temper.
