Introduction	1.2083 Tool Steel is martensitic stainless steel with 12% Chromium which is sufficient to give good corrosive resistance properties. It's best corrosive resistance is when hardened and surface is ground or polished. It has good ductility in the annealed condition but can be hardened up to 500HB (highest of the chromium grades). Martensitic Grades are known for high hardness and allowances must be made for poor weldability and usually, allowances for a final harden and temper treatment. Steel is magnetic and welding is not recommended.

2. Fabrication and Heat Treatment: Heat Treatment:
Forging: 1.2083 mold steel are forged at 1093°C (2000°F) down to 899°C (1650°F). Forging below 871°C (1600°F) is not recommended for these steels.
Annealing: 810 - 830 °C
Hardness after annealing: Max230 HB
Stress-relieving: Approx. 650 °C
Hot forming: 1050 - 850 °C
Hardening: 970 - 990 °C
Quenching media: Oil, Vacuum
Hardness after quenching: 30-36 HRC
Hardness after tempering
