PLASTIC MOLD STEEL-(Grade 1.2738,P20+Ni,AISI P20+Ni)

Grade 1.2738 steel is one sort of plastic mold steel, equal to AISI P20+Ni plastic  mold device steel. Grade 1.2738 is a plastic mold tool metallic, used specially for plastic injection die moulds. While Nickel, chromium and molybdenium are the alloying factors for hardness and durability. Grade 1.2738 steel device metal is mainly designed for plastic mold enterprise, in particular for big metallic mold elements.

Grade 1.2738 steel is commonly supplied as pre-hardened/quenched and tempered 280 – 320 (BHN) HB hardness and 32-36 HRC hardness condition with exact machinability. The p20 steel 1.2738 is melted in an electrical furnace and refined with VOD or DH device.The steel is machinable, polishable, and appropriate for texturing. Welding is fairly difficult, but viable. Make positive to pre-heat and carry out tempering, whilst the piece colled down after welding.

Application of Grade1.2738,P20+Ni:

1.2738 mould metal substances are normally used for rather low-temperature programs which includes die-casting dies and injection molds, synthetic plastic molds dies, in particular for huge plastic molds exceedingly stressed inside the core, hydroforming equipment, which includes up to 400 mm within the construction of plastic molds. DIN 1.2738 is suitable for nitriding and chrome plating.

P20 + Ni applicable for big & small plastic mold dies for Automotive Industries, Dies for Domestic items , High completing plastic Die, Boaster Plates of Presses, Die Holders & Shoe blocks for drop Hammers, Press Cassettes , Upsetter Blocker, forging dies, Different dies & mildew for plastic merchandise and so on.
