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.

The modified version of is with High Hardness 360-400 BHN and increase alloy elements to get extra life and outstanding polishing.
DIN steel is a type of plastic mold steel that is similar to P20+Ni /AISI P20+Ni Tool Steel. The alloying elements for hardness and toughness include nickel, chromium, and molybdenum. DIN tool steel is intended specifically for the plastic mold industry, particularly for large steel mold components. DIN tool steel is often provided pre-hardened/quenched and tempered in the 280 - 320 HB hardness range. This makes it a great choice for applications involving high-temperature settings and difficult mechanical conditions.
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.

Surface Finish: Black Surface, Roughly Machined, Peeled & Turned or as per given requirements.
Usually already pre-toughened, no heat treatment required, if there is no special requirements.
710 to 740 °C for about 2 to 5 hours; then cool slowly of 10 to 20 °C per hour to about 600 °C further cooling in air, This will produce a maximum Brinell hardness of 235.
Harden from a temperature of 840-870°C followed by oil, then quenching in oil/hot bath/air 180~220 °C. Hardness after quenching is around 52 HRC.
Slow heating to tempering temperature immediately after hardening; and minimum time in furnace: 1 hour per 20 mm part thickness; tempering twice is recommended.
