W 1.2083

W1.2083 is a mould steel with improved corrosion resistance properties.

W1.2083 is generally delivered annealed with a hardness < 230HB. It can also be delivered hardened and tempered to 320 HB.

Main characteristics of this grade are :
– a good atmospheric corrosion resistance,
– an excellent polishability,
– a good machinability in annealed condition,
– a high hardenability
– a good wear resistance
