DIN 1. 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 is upgraded version of plastic mold steel 0f , 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.
DIN is a premium mold steel that offers excellent polishability, wear resistance, and toughness, making it ideal for a wide range of tooling applications. DIN is a specially designed mold steel with improved toughness and excellent machinability compared to standard P20 grades.
DIN 1. 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. DIN steels have superior polishability compared to 1. (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 steel is melted in an electrical furnace and refined using a VOD or DH equipment.
Chemical Composition:
DIN : Carbon (C): 0.35-0.45%, Manganese (Mn): 1.30-1.60%, Silicon (Si): 0.20-0.40%, Phosphorus (P): ≤ 0.030%, Sulfur (S): ≤ 0.030%, Chromium (Cr): 1.80-2.10%, Nickel (Ni): 0.90-1.20%, Molybdenum (Mo): 0.15-0.25%
P20+Ni: Carbon (C): 0.28-0.40%, Manganese (Mn): 0.60-1.00%, Silicon (Si): 0.20-0.80%, Phosphorus (P): ≤ 0.030%, Sulfur (S): ≤ 0.030%, Chromium (Cr): 1.40-2.00%, Nickel (Ni): 0.80-1.20%
