3 Standard and Grade:
ASSAB: S-136, AISI 420ESR, DIN 1.2083
4Cr13 steel,420 steel,1.2083 steel
4 Application:
AISI 420ESR 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 molds, e.g. sunglasss and optical instruments.
5 Characteristics:
AISI 420ESR is an alloy that is developed by absorbing the adventages of foreign similar mirror steel like AISI 420ESR and added with fine structure element based on 1.2083.
