DIN 2738 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. DIN 2738 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.<\/p>\n\n\n\n
DIN 2738 is a premium mold steel that offers excellent polishability, wear resistance, and toughness, making it ideal for a wide range of tooling applications. DIN 2738 is a specially designed mold steel with improved toughness and excellent machinability compared to standard P20 grades.<\/p>\n\n\n\n
DIN 1.2738<\/a> is a widely used cold work steel, especially in the plastic mold industry. It is equivalent to P20+Ni and AISI P20+Ni tool steel.<\/strong> DIN 2738 steels have superior polishability compared to 1.2312 (AISI P20+S) and better machinability. To enhance the hardness and wearability of the mould surface material , it can be treated with nitrogenation and flame hardening. DIN 2738 steel<\/a> is melted in an electrical furnace and refined using a VOD or DH equipment.<\/p>\n\n\n\n DIN 2738: <\/strong>Carbon (C): 0.35-0.45%, Manganese (Mn): 1.30-1.60%, Silicon (Si): 0.20-0.40%, Phosphorus (P): \u2264 0.030%, Sulfur (S): \u2264 0.030%, Chromium (Cr): 1.80-2.10%, Nickel (Ni): 0.90-1.20%, Molybdenum (Mo): 0.15-0.25%<\/p>\n\n\n\n P20+Ni:<\/strong> Carbon (C): 0.28-0.40%, Manganese (Mn): 0.60-1.00%, Silicon (Si): 0.20-0.80%, Phosphorus (P): \u2264 0.030%, Sulfur (S): \u2264 0.030%, Chromium (Cr): 1.40-2.00%, Nickel (Ni): 0.80-1.20%<\/p>\n\n\n\n DIN 2738 Steel:<\/strong> P20+Ni:<\/strong> Density:<\/em> DIN 1.2738<\/a> and P20+Ni<\/mark><\/strong> <\/a>have a density of approximately 7.85 g\/cm\u00b3.
