PROPRIETARY DX1803 Heat Treatments
- This material is not meant for continuous use at temperatures above 300°C:
Use in temperatures ranging from 350 - 550°C will result in the ferritic phase losing ductility. This is due to the formation of the so-called 'α’ phase, possibly accompanied by other embrittling phases. Commonly referred to as 475°C embrittlement, this phenomenon is common to ferritic stainless steels.
Due to the material’s high chromium and molybdenum content, use in temperatures between 600 and 950°C will result in embrittling Sigma phase precipitation.
Annealing:
After cold forming, an annealing treatment of a couple of minutes at 1050 +/- 25°C, followed by air cooling restores the structure and eliminates internal stresses. After heat treatment, pickling followed by passivation must be carried out.
