DIN 1.2083 is typical Stainless Chrome Plastic Mold Steel. German die steel 1.2083 is a chromium content up to 13% of the plastic die steel. 1.2083 mold steel has good polishing and excellent wear resistance, is often used to prevent acid plastic mold. Special Steel China Supplier and factory -OTAI SPECIAL STEEL COMPANY supply 1.2083 steels in round bar, plate, flat bar, square, block and others any shape.

Forged of 1.2083

Pre-Heating to 600℃，Then heat to forged temperature. Soak at 800-1100°C, ensure heat thorough. Then start forged, the forged temperature no low than 650℃. After forging, cool slowly.

Heat Treatment of DIN 1.2083 Plastic Steel
  • 1.2083 Annealing

Slowly heat to 750-800℃，then slowly Cools to 538℃(1000℉) in heat treatment furnace. Then cool in air. After annealing hardness HBS: 225 Max

  • Din W-Nr 1.2083 Hardening

1.2083 steel having very high hardenability and should be hardened by cooling in still air. The use of a salt bath or controlled atmosphere furnace is desirable to minimize decarburization, and if not available, pack hardening in spent pitch coke is suggested.

  • Quenching of Stainless Plastic mold 1.2083 material

Quenching temperature / ℃ : 1020~1050

Quenching medium: Oil cooling

Hardness: 50 HRc

  • Tempering Of 1.2083

Tempering temperature / ℃ : 200-300

After tempering hardness HRC or higher: 28-34 HRc

Application of Din X42Cr13 W-Nr 1.2083

1.2083 is suitable for electric erosion operation, suitable for acid good polishing mold plastics and requirements. Mainly used in the production of PVC mold, wearability and filling the mold, including the hot hard type of plastic mold, long-life mold, such as: disposable tableware mold, optical components production, such as camera, and the sunglasses, medical containers and etc.
