Austenitic stainless steel are made using up to 80% scrap iron. Not only is stainless steel an alloy of iron, but depending on the fabrication process, it can be loaded with tramp elements and inclusions detrimental to finishing requirements and corrosion resistance. Austenitic stainless steel have been the workhorse of the sanitary food and pharmaceutical industry for years. However, for reasons mentioned above, processors are beginning to use more corrosion resistant alloys to achieve the required life-cycles for their systems. One such material is Hastelloy® C-22®.
ASTM B622 ASME SB 622 N06022 C22 alloy is one of the most versatile nickel-chromium-molybdenum-tungsten alloys available today. This alloy demonstrates improved corrosion resistance to both uniform and localized corrosion and will exceed the performance of C276, C4 and alloy 625 in a variety of corrosive environments.
