DIN 1.2083 Steel Round Bar Sheet Plate
DIN 1.2083 steel is the most popular one for the type of stainless plastic mold steel. It is a good material, especially for the high-level mirror plastic mold. DIN 1.2083 plastic mold steel has great wear resistance with high Cr. The content of Cr is more than 15%. And it has good polishing performance properties and machinable properties. After quenching, it will get better wear resistance, will be a great material for mold with acid plastic and high polishing property requirements. And people usually called it as 2083 steel.

1.2083 Steel Application
DIN 1.2083 steel has good polishability and excellent wear resistance, very suitable for molds of corrosive plastic materials (such as PVC, recycled polymers, etc.), acid aggressive plastics, etc., and is also widely used in the medical and tableware industries. Used in automotive molds, instruments, glasses, plastic templates, knives, hand tools, pump shafts and plastic molds, etc.
DIN 1.2083 Heat Treatment
Forging of 1.2083 Steel
1.2083 plastic mold steel is forged by slowly and evenly heating to temperatures between 1093°C (2000°F) and 899°C (1650°F). After forging, cool slowly in the furnace or in the insulation material.
Annealing
For maximum softness, heat slowly and uniformly to 760 – 800°C, then cool slowly in the furnace.
Relieve Stress
Stress relieved to minimize the risk of deformation or cracking during subsequent heat treatment.
After rough machining, the steel is slowly heated to 650°C, soaked for at least two hours per 25mm section, slowly cooled to 500°C, then cooled in air
Or quenched in oil or water.
Hardening
Preheat first, then heat to 600-850°C until heated through, then harden from 980-1050°C and allow to heat completely. Use a neutral salt bath, controlled atmosphere furnace, or vacuum to protect components from decarburization. Soak at a certain temperature. Air cool or quench in warm oil.
Tempering
In order to achieve the best alignment of hardness, toughness and corrosion resistance, tempering at 250°C-570°C is recommended.
