wwwwww..ssppeecciiaallmmeettaallss..ccoomm INCOLOY® alloy 25-6MO (UNS N08926/W. Nr. 1.4529, formerly UNS N08925) is a Table 1- Limiting Chemical super-austenitic stainless steel containing Composition, % (UNS N08926) 6% molybdenum and enhanced by an addition of nitrogen. The nickel and Nickel24.0-26.0 chromium contents of this alloy make it IronBalance* resistant to a wide range of corrosive Chromium19.0-21.0 environments. The alloy is especially resistant Molybdenum6.0-7.0 to non-oxidizing acids such as sulfuric and Copper0.5-1.5 phosphoric. The high molybdenum content O Nitrogen0.15-0.25 and nitrogen provide resistance to pitting and Carbon0.02 max. crevice corrosion, while copper enhances resistance to sulfuric acid. The complete Manganese2.0 max. M limiting chemical composition is given in Phosphorus0.03 max. Table 1. Sulfur0.01 max. 6 INCOLOY alloy 25-6MO is a fully Silicon0.5 max. - austenitic alloy containing 6% molybdenum and offering excellent corrosion resistance in *Reference to the ‘balance’ of a composition d
