  • Alloy 31 - a high alloyed Ni-Cr-Mo-steel - properties and applications for the process industry = Alloy 31 - visoko legirano Ni-Cr-Mo jeklo - lastnosti in aplikacije za procesno industrijo
    Mast, Ralph ...
    Alloy 31 (Nicrofer 3127 hMo) is an austentic nickel-chromium-molybdenum steel comprising about 0.2 wt-% nitrogen to stabilize the austenitic structure. The alloy was developed to fill the gap between ... the commercial stainless steels and the nickel-base alloys. It is a material for many high-severity applications where conventional stainless steels have proven unadequate. On the other hand, Alloy 31 shows a high resistance to pitting and crevice corrosion in neutral and acid aqueous solutions, coming close to that of higher nickel alloyed materials. Laboratory tests in different aqueous solutions have proven that Alloy 31 is characterized by an excellent resistance to both reducing and oxidizing media. The corrosion resistance to oxidizing media is caused by the high chromium content and is not impaired by the molybdenium content of about 6.5 wt-%. Additionally, the high resistance to pitting and crevice corrosion corresponds to the additions of molybdenium and nitrogen. The paper describes some typical industrial and practical applications of Alloy 31. For example the material is successfully used for filter systems and mixer components in phosphoric acaid plants, for waste sulfuric acid recovery and for FGD (flue gas desulfurisation) systems. For such applications not only corrosion and erosion-corrosion raesistance but also high strength, high ductility and ease of fabrication such as welding are important parameters.
