Alloy31 is an iron-nickel-chromium-molybdenum alloy with nitrogen addition. The alloy fills the gap between special alloyed austenitic stainless steels and nickel alloys. Alloy 31 has been proven especially in the chemical and petrochemical industry, in ore extractors, environmental and marine engineering as well as in oil and gas production.
Some features of Alloy 31 are:
- Excellent resistance to corrosion and erosion in phosphoric acid media
- Excellent resistance to general and localized corrosion in Chloridoxid bleaching plants in paper production
- Certification to ISO 15156/MR 0175 to level VI for sour gas applications in the oil and gas industry
- Excellent resistance in reducing and oxidizing media, as well as in boiling 67% nitric acid
- Excellent corrosion resistance in alkaline and acid halide media
- Approval for pressure vessels with operating temperatures from -196 to 550 ° C
- Good processability and weldability
-Excellent resistance to sulfuric acid in a highly concentrated form
