Description

DIN 1.2738 Steel Plate is a type of plastic mold making steel.

its equivalent to AISI P20+Ni tool steel.

Whereas Nickel, Chromium, and Molybdenum are the alloying elements for hardness and hardness.

Buy DIN 1.2738 Steel Plate in Delhi, Gurugram, Noida, Manesar.

1.2738 Tool steel is specially designed for the plastic mold industry, especially for large steel mold parts.

  • DIN 1.2738 tool steel is usually supplied as pre-hardened/quenched and tempered 32–34 HRC hardness condition with good machinability.
  • DIN 1.2738 steels are with better polish-ability compared to 1.2312 (AISI P20+S).
  • Material 1.2738 can be obtained through nitrogenation and flame hardening treatment to increase the hardness and wearability of the mold surface.
  • The steel 1.2738 is melted in an electrical furnace and refined with a VOD or DH device.

DIN 1.2738 Mold Tool Steel Properties.

  • Physical properties at ambient temperature.

Modulus of elasticity [103 x N/mm2]: 205

Density [g/cm3]: 7.80

Thermal conductivity [W/m.K]: 29.0

Specific heat capacity[J/g.K]: 0.46

Strength:≈ 1080 N/mm²

Thermal Conductivity at 100 °C:33.5 W/m K

Forging of 1.2738 Tool Steel.

Hot forming temperature: 1093-898 °C.

Heat Treatment of Mold Steel 1.2738.

  • Heat Treatment of 1.2738 steel blocks.

Usually already pre-toughened.

no heat treatment is required if there are no special requirements.

 

  • Soft annealing.

710 to 740 °C for about 2 to 5 hours; then cool slowly to 10 to 20 °C per hour to about 600 °C, further cooling in the air. This will produce a maximum Brinell hardness of 235.

  • Hardening of DIN 1.2738 Steel Plate:

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.

 

  • Tempering of material.

Slow heating to temper temperature immediately after hardening and minimum time in the furnace is 1 hour per 20 mm part thickness; tempering twice is recommended.

7. Applications of DIN 1.2738 Steel.

DIN 1.2738 mold steel materials are generally used for relatively low-temperature applications such as die-casting dies and injection moulds, synthetic plastic moulds dies, especially for large plastic moulds highly stressed in the core, hydroforming tools, such as up to 400 mm in the construction of the plastic moulds.

DIN 1.2738 is suitable for nitriding and chrome plating.
