Thyssenkrupp 2083

Thyssenkrupp 2083 Plastic Mould Steel

Characteristic

2083 is a tool steel in the group of plastic mold and stainless in matesitic (AISI420)
So, it can stand for corrosive and can be quench to enhance it’s strength together
with corrosive resistance properties
Tool steel with high dissolved Cr content in the steel matrix. Good corrosion resistant in the hardened condition, good pol- ishability, good machinability, low distorsion, high wear resisatnce and high surface finish. This grade can be produced on request by the process ESR and quenched and tempered condition.
Hardness can reach up to 56 HrC , this also benefit to polishing properties and can do texturing.
Suitable for plastic mold that need corrosive resistance such as amino plastic,
thermoplastic which has severe decompose of acitic acid as well as PVC plastic

Advantage 2083

• Corrosive resistance
• Hardness homogeneity through all area after hardening
• High strength and tensile
• Polishing properties
• Abrasive resistance
• Machining ability
• Texturing ability
• Welding ability

Heat Treatment 2083 Plastic Mould Steel

• 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

Application

2083 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, etc. 2083 also suitable for electric erosion operation, suitable for acid good polishing mold plastics and requirements, such as Amino plastic, thermo plastic PVC Plastic Moreover, it can stand for abrasive and wear, so this is good for plastic thermo setting mold Thanks to its polishing ability,
it can be used for Spectacular lens, camera lens, science experimental tube, syringe Also, good for any cutting task like knife, cutting tool, kitchen utensil, spring, seal valve or machine part for mining/wood industry. Ruler and Slider calipers
