Characteristics
- Good creep resistance at temperatures above 600 ° C.
To avoid a weakening in strength between 500 and 700 ° C the content of Al + Ti is limited to max.0.7% - Good resistance to oxidizing, reducing and nitriding atmospheres and at varying oxidizing and carburizing conditions
- Metallurgical stability in long-term use at high temperatures
Caution: If temperature 500-700 ° C is passed often during the process, 800h should be preferred. Alloy 800HT may show detrimental phases.
Hot forming
The material is hot formed within a temperature range of 900 and 1200 ° C and afterwards quenched rapidly in water or air. Hot bending is carried out at 1000 to 1150 ° C.
The annealing takes place at 1200 ° C.
Holding time about 60 min. / 100 mm thickness.
After hot forming, heat treatment for optimum creep strength is recommended.
Cold forming
The material has a higher work-hardening rate than austenitic stainless steels. The workpiece should be available in the annealed condition. For strong cold forming intermediate annealing is necessary.
For more than 10% deformation, annealing should be performed.
Heat treatment
The solution annealing is carried out at 1150 ° C. It should be cooled quickly under water.
With thicknesses less than about 1.5 mm rapid air cooling can be done.
