4. Steel 1.2083 Steel Properties
Modulus of elasticity [103 x N/mm2]: 220
Density [g/cm3]: 7.80
Specific heat capacity[J/g.K]: 0.46
5. Forging of 1.2083 Stainless Steel
- Hot forming temperature: 1050-850oC.
6. Heat Treatment
Heat to 760-800oC, cool in furnace slowly.
After rough machining the steel should be heated through to 650°C, holding time 2 hours. Cool to 500°C slowly, then freely in air.
Preheating temperature: 600–850°C. Harden from a temperature of 1000-1050oC followed by oil, vacuum, pressure gas (N2), air or hot bath ar 500-550 C quenching. Protect the part against decarburization and oxidation during hardening. Soaking time: 1020°C, 30 minutes, 1050°C, 30 minutes. Soaking time = time at hardening temperature after the tool is fully heated through.
Tempering temperature: 250-570oC.
7. Applications of 1.2083 Steel
It’s usually used for plastic mould plates and inserts for working with chemically aggressive plastics; because of excellent polishing, it is also suitable for optical and medical products.
