| | | |
| | | combined with high hardness Very good polishability Grain reliable Good suitability for hard chrome plating | | |
| | | Low-distortion, air quench through-hardening, nickel alloy tool steel with excellent toughness characteristics; very good polishability and grain reliable. This type of steel is particularly suitable for all large and medium-sized highly stressed compression and injection moulds that are pre-machined and contour hardened, such as injection moulding of transparent resins and large-surface plastic parts such as tailgates and mudguards, also mould inserts for high levels of hardness up to 54 HRC, and abrasive stress. Simple heat treatment with cooling in air ensures hardness of30 - 54 HRC, universal suitability and very good polishability. | | |
