Description:
heat treated steel to reach approx. hardness of 30 HRC, very good machinability (due to no sulphur content better than 1.2311 ), polishability worse than 1.2311
Application:
injection moulds, large bodies and inserts for plastic moulds and pressure moulds, where high polishability is not required
