P20
General
P20 TOOL STEEL IS A PRE-HARDENED PLASTIC MOULD STEEL KNOWN FOR ITS EXCELLENT TOUGHNESS AT MODERATE STRENGTH LEVELS, MAKING IT A HIGHLY ADAPTABLE MATERIAL FOR ENGINEERING USE. THE PRESENCE OF NICKEL AND CHROMIUM IN THE ALLOY ENHANCES BOTH ITS HARDNESS – CONSISTANT THROUGHT LARGE SECTIONS - AND TOUGHNESS. P20 ALSO OFFERS GOOD WELDABILITY AND HIGH-QUALITY POLISHED FINISH. FOR APPLICATIONS THAT DEMAND INCREASED SURFACE HARDNESS—LIKE COMPRESSION MOULDING PLASTIC DIES—CASE HARDENING OR NITRIDING CAN BE APPLIED.
Uses
TOOLING, DIE CASTING MOULDS, PLASTIC MOULDS.
