Material Grade Hardness Characteristics Applications
CN P20 MOD Prehardened to HB250 - 360 Economical choice of pre-hardened plastic mould steel Mould base/plate with high strength requirement for plastic injection mould; core/movable part of plastic injection mould without high surface finish requ irement
CN 2311 Prehardened to HB260 - 340 Prehardened plastic mould steel Mould base/plate with high strength requirement for plastic injection mould; core/movable part of plastic injection mould without high surface finish requ irement
CN 718 Prehardened to HB280 - 330 Prehardened plastic mould steel, hardness homogenei ty is better than normal AISI P20 plastic mould steel Mould base/plate with high strength requirement for plastic injection mould; core/movable part of plastic injection mould without high surface finish requ irement
CN 718H Prehardened to HB330 - 380
CN 420 Annealed to HB240(max) Good anti-rusting property Plastic injection mould for long production run with simple geometry and anti-rusting property but without high surface finish requirement
CN 420H Prehardened to HB280 - 330 Pre-hardened stainless steel Plastic injection mould for small to medium production run with simple geometry and anti-rusting property but without high surface finish requiremen t; suitable for mould base/plate with anti-rusting property
CN H13 Annealed to HB225(max) Economical choice of hot work steel Through-hardened plastic injection mould for those non-corrosive resins; slider and lifter for plastic injection mould; small size of Zn die casting die for small to medium production run
