Principal Feature:

Plastic mould steel with excellent machinability properties because of the high S content, good toughness properties,good wear resistance, uniform hardness in all dimensions, dimensional stability, requiring no heat treatment, 280 - 325HB hardened and tempered condition, suitable for nitriding to increase wear resistance, not suitable for chrome plating,polishing and etch graining.

Typical Application:

Suitable for large-scale long-life plastic injection mold, such as home appliances, computer case etc.
surface finish of plastic products mold; blow mold;
