S136/420/1.2083/4Cr13 plastic mould steel
Profile:Manufacturer - Producer|Ref:PSL210385YH | Country: China | Currency: usd | Export: No
Superior resistance to corrosion, no need for special care or maintenance; S136 is smelted by using vacuum degassing, so that the quality is more purified, the structure is even dense and the polish property is excellent; already pre-hardened and no need for further heat treatment, suitable for direct mold cutting.
S136 is suitable for plastic molds, and has better antirust properties for the molds used under wet environment. It is mainly used for making of the high-quality transparent plastic moulds, like sunglasses and optical instruments.
