1.4562 Alloy 31
The alloy 31 is a iron-nickel-chromium-molybdenum alloy with addition of nitrogen. The alloy close the gap between high-alloy austenitic special stainless steel and nickel alloys.
- excellent corrosion resistance in alkaline and acidic halide-containing media;
- a excellent resistance to sulfuric acid, even in strong concentrated form;
- a excellent resistance to corrosion and erosion in phosphoric acid media;
- finally, an excellent resistance to reducing and oxidizing media and against boiling azeotrope nitric acid.
