Product Desciption
Abrasion resistance Tool Steel for plastic Mould (1.2738/P20+Ni/3Cr2NiMo/718)
1.2738 tool steel is a 300HB (30HRC) pre-hardened grade specially designed for plastic mold industry. Chromium, Molybdenum, Nickel carbon and manganese additions are optimized to have a fully martensite-bainite microstructure after quenching. The high nickel content (1%) is specially adapted to ensure a perfect homogeneity of structure and hardness through thickness even for very thick blocks (up to 700mm/28"). The steel is melted in electrical furnace and refined with VOD or DH device The cleanliness of the steel is guaranteed as well as the soundness. This makes the steel particularly well adapted for mold even when polishing or chemical etching are required for surface finish quality.
1.2738 tool steel is specially used for Plastic injection die moulds. The characteristics of a material are right sharpening, photo-etching properties with high purity and good homogeneity. 1.2738 P20+Ni 3Cr2NiMnMo is upgraded version of plastic mold steel 0f 2311, which normally supply in Pre hardened condition. Hardness in as supplied condition 280-320 HB with having uniform hardness. The additional nickel content of 1 % increases through hardening. It has good machinability, suitable for Texturing, fine polishability, adequate corrosion resistance, vacuum-degassed steel.
Compare with P20, 1.2738(P20+Ni 3Cr2NiMo) tool steel will be more suitable for larger size plastic parts injection operation.
1.2738 tool steel is applicable for large & small plastic mould dies for Automotive Industries, Dies for Domestic goods , High finishing plastic Die, Boaster Plates of Presses, Die Holders & Shoe blocks for drop Hammers, Press Cassettes , Upsetter Blocker, forging dies, Different dies & mold for plastic products etc.
