Pre-hardened mould steel with nickel addition for uniform hardness through large cross-sections. Delivered at 280-325 HB. The Ni addition (0.90-1.20%) provides better through-hardening than 1.2311/1.2312, making it suitable for large moulds with sections >400mm. Used for large injection moulds for automotive, household appliance, and furniture industry. The standard choice for large, complex mould frames. Similar to AISI P20+Ni.

Pre-hardened corrosion-resistant mould steel (30–36 HRC as delivered). 16% Cr provides stainless-like corrosion resistance — no surface pitting during storage, no rust contamination of moulded parts. Sulfur addition improves machinability. Used for moulds processing corrosive plastics (PVC, acetals, flame-retardant compounds), food packaging moulds, moulds stored in humid environments and prototype tooling. Can be directly machined in pre-hardened state without additional heat treatment.

High-toughness nickel-alloyed tool steel for plastic molds and cold work applications. 4% Ni provides exceptional impact toughness at hardness levels of 48–54 HRC. Through-hardening up to very large cross sections. Used for injection mold frames, blow mold inserts, cold stamping tools requiring high toughness, tire molds and machine knives. Polishable to mirror finish. Can be nitrided for improved surface hardness.
