Forging:
Heat slowly and uniformly to 1000°C. After Forging cool slowly.
Annealing:
Heat slowly to 780°C. Slowly cool in furnace.
Hardening:
Pre heat to 600-700°C until heated through. (Austenitizing temperature 1025°C.) Continue heating to the final hardening temperature of 980-1050°C and allow the component to be heated through. Protect against decarburisation by using neutral salt bath, controlled atmosphere furnace or vacuum. Air cool or quench in oil.
Tempering:
Heat uniformly and thoroughly at the selected tempering temperatures and hold at heat for one hour per inch of total thickness. Double tempering is recommended.

Nitriding:
Nitriding of 1.2083 gives it a hard surface which is very resistant to wear and corrosion. Howe ver , the nitrided surface reduces the corrosion resistance. Surface hardness after nitriding at 525°C in ammonia gas will be approximately 1000HV.

Welding:
Due to the high risk of crack formation Welding of 1.2083 stainless steel should be avoided, if possible. When, howe ver Welding is essential, the following serves as a guide:
A. Welding of soft annealed 1.2083 stainless steel.
· Preheat to 300 - 500°C
· Weld at 300-500°C
· Immediately stress relieve
B. Repair Welding of 1.2083 stainless steel in hardened and tempered condition.
· Preheat to the tempering temperature (min. 200°C) previously used.
· Start Welding at tempering temperature
· Re heat immediately to tempering temperature, but max. 300°C. Soaking time 3 hours.
· Cool in air to approximately 80°C.
· Re heat immediately to tempering temperature, but max. 300°C. Soaking time 3 hours.
Electrode: Hard facing electrode.
