P20+Ni 1.2738 718hh 3cr2nimo Alloy Steel Tool Steel Round Bar Flat Bar

DIN 1.2738 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 of 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.

 

The modified version of 2738 is with High Hardness 360-400 BHN and increase alloy elements to get extra life and outstanding polishing.

DIN 2738 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 2738 tool steel is intended specifically for the plastic mold industry, particularly for large steel mold components. DIN 2738 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 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 is melted in an electrical furnace and refined using a VOD or DH equipment.

 

Physical Properties

The physical properties can vary slightly depending on the specific composition and heat treatment of the P20+Ni /DIN 2738 /AISI P20+Ni steel. It's always recommended to refer to the manufacturer's specifications for precise information.

Heat Treatment & Processes:

Heat Treatment

P20+Ni / DIN 2738 / AISI P20+Ni is already pre-toughened, thus no heat treatment is necessary if no particular needs exist.

Hardening:

Harden from 840-870°C, followed by oil, and finally quench in oil/hot bath/air 180-220 °C. The hardness after quenching is approximately 52 HRC.

Tempering:

After hardening, slowly heat the part to the tempering temperature; the minimum duration in the furnace is one hour for every 20 mm of part thickness; two tempering is advised.

Forging:

1093-898 °C.

Stress Relieving:

Approx. 650°C.
