Product Description
DIN 1.2083 4Cr13 SUS420J2 415 Plastic Mould Steel Plate
1: DIN 1.2083 Steel Introduction
1.2083 Steel 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 2083 steel in round bar, plate, flat bar, square, block and others any shape.

7: DIN 1.2083 Steel Application
DIN 1.2083 is applicable 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.
8: DIN 1.2083 Steel Heat Treatment
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
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
Quenching temperature / ℃ : 1020~1050
Quenching medium: Oil cooling
Hardness: 50 HRc
Tempering
Tempering temperature / ℃ : 200-300
After tempering hardness HRC or higher: 28-34 HRc
