Mould steel;Nickel and chromium are the alloying elements for hardness and toughness.Good machinability, excellent polishability, suitable for texturing. Improved through hardenability compared to Mat.No. 1.2311.
Enduse = Typically used for relatively low temperature applications such as die casting dies and injection molds, synthetic plastic moulds dies, for large moulds.
