OEM No/Model: 1.2083
Grade
ASSAB: S136, AISI 420, DIN 1.2083,GB 4Cr13
Performance Characteristics:
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.
Applications:
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.
