alloy f255 corrosion materials
The addition of alloy material such as chromium, molybdenum and nitrogen in predefined amounts make it very much corrosion resistive. It is designed to have a PREN number larger than 40, which means it is highly resistive to pitting than all the austenitic type of steels. 255 - Rolled Alloys, Inc.Alloy 255 is a 25% chromium super duplex stainless steel. Alloy 255 contains a copper addition which provides it with greater resistance to sulfuric acid than other super duplex grades. Because of its duplex structure alloy 255 also offers excellent strength characteristics and resistance to chloride ion stress corrosion cracking.
- DescriptionIndustries and ApplicationsResistance to CorrosionFabrication and Heat TreatmentCommon Trade NamesAlloy 625 is a nickel-chromium-molybdenum alloy that is used for its high strength, high toughness and excellent corrosion resistance. The strength of alloy 625 is derived from the stiffening effect of molybdenum and niobium on its nickel-chromium matrix. Although the alloy was developed for high temperature strength, its highly alloyed composition also provides a significant level of general corrosion resistance.The Global Leader in Specialty MetalsF255 UNS S32550 25.5 5.5 3.4 0.175 2.0 balance 39.5 *PRE N = CR + 3.3(Mo + 0.5 W) + (16N) Iso-corrosion Curves Iso-corrosion curves 0.004 ipy (0.1 mm/y) for some stainless steels in Hydrocloric Acid Iso-corrosion curves 0.004 ipy (0.1 mm/y) for some stainless steels in Sulfuric Acid F255 Minimum Tensile Properties

Alloy 255 is replacing admiralty bronze, and the nickel alloys, in offshore platforms, deck hardware, rudders and shafting. Alloy 255 is also making inroads in "borderline" corrosion applications where the nickel alloys and high performance alloys have been used but may not have been absolutely necessary.

Your Corrosion Resistant Nickel Alloy Experts Corrosion Your Corrosion Resistant Nickel Alloy Experts. Many of Corrosion Materials customers commonly work with carbon steel, carbon alloy, stainless steel and aluminum. However, these alloys may not hold up in harsh environments, such as aggressive media, elevated temperatures or a combination of the two. That is when companies turn to nickel alloys.
F255 Alloy F255 is a highly alloyed, super duplex (ferrite-austenite) solid solution strengthened alloy, which provides high strength and wear resistance while oering superior corrosion resistance compared to 316 stainless steel.
