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. |
6.Heat Treatment
Annealing
Slowly heat to 750-800ºC,then slowly Cools to 538ºC(1000ºF) 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 / ºC : 1020~1050
Quenching medium: Oil cooling
Hardness: 50 HRc
Tempering
Tempering temperature / ºC : 200-300
After tempering hardness HRC or higher: 28-34 HRc
For hot rolled plate, usually the delivery condition is hot rolled, annealed, black surface.
