444 STAINLESS STEEL Product Description Type 444 is a low-carbon (C), low nitrogen (N), dual-stabilized ferritic stainless steel that provides pitting and crevice corrosion resistance superior to most ferritic stainless steels and some austenitic stainless steels. Type 444 Alloy C-276 (HASTELLOY®) Double Eagle AlloysAlloy C-276 (HASTELLOY®) is a nickel-molybdenum-chromium-iron-tungsten alloy which is among the most corrosion resistant of alloys currently available. The C-276 alloy is widely used in the severest environments encountered in the chemical and petrochemical processing, flue gas desulfurization, pulp and paper and other specialized fields. C-276 Seamless Nickel Tubing - (ASTM B622, ASME SB622 Alloy C276 seamless nickel tubing is a nickel-molybdenum-chromium alloy with addition of tungsten having excellent corrosion resistance in a wide range of severe environments. The high molybdenum content makes this alloy especially resistant to pitting and crevice corrosion.
These alloys can however suffer from caustic stress corrosion cracking at caustic concentrations above 70% at temperatures above 290-Cr-Mo °C (550°F). The Ni alloys such as C-276 (N10276) also have useful caustic cracking resistance, however are susceptible to Choosing Specialty Metals for Corrosion-Sensitive The most corrosion-resistant grades are ium 7, 11 (containing 0.15% palladium), and 12 (containing 0.3% Mo and 0.8% Ni). In the chemical process industries, titanium and its alloys offer good corrosion resistance in many process environments. ium provides more protection than stainless steel because it has a greater af nity for oxygen Comparision Grade 304 304L 316 316L Corrosion ResistanceComparision Grade 304 304L 316 316L Corrosion Resistance. As American AISI basic grades, the only practical difference between 304 or 316 and 304L or 316L is carbon content. The carbon ranges are 0.08% maximum for 304 and 316 and 0.030% maximum for the 304L and 316L types. Corrosion Resistance of Hastelloy C-276 to Hydrochloric AcidHastelloy C-276 has outstanding resistance to hydrochloric acid. It is resistant to all concentrations of hydrochloric acid at room temperature, and can be employed successfully up to about 120°F [49°C].

Alloy C-276 Nickel Alloys. Alloy C-276 (Hastelloy ® C-276) contains nickel, molybdenum, and chromium. Its high molybdenum content makes it exceptionally resistant to pitting and crevice corrosion, and it is one of only a few materials that can withstand the corrosive effects of Hastelloy C-276 Corrosion Resistance to Sulfuric AcidHastelloy C-276, UNS N10276 or W.Nr. 2.4819, is the most universally corrosion-resistant nickel alloy. It is widely used in various applications involving sulfuric acid of an extensive range of concentrations and temperatures. Nickel Alloy C-276, Hastelloy® C-276 - Continental Steel Because of Hastelloy C-276s outstanding corrosion resistant capabilities, it is used by a wide variety of industries for critical applications including:Almost anything used around sulfuric acid (heat exchangers, evaporators, filters, and mixers) Bleach plants and digesters for the manufacturing of paper and pulp. Nickel Alloy C-276, Hastelloy® C-276 - Continental Steel Hastelloy® C-276, which is also sold as Nickel Alloy C-276, is a nickel-molybdenum-chromium wrought alloy. Hastelloy C-276 is perfect for use in situations that demand protection from aggressive corrosion and localized corrosion attack. This alloy Other important features of Nickel Alloy C-276 and Hastelloy C-276 include its resistance to oxidizers like:Ferric and cupric chlorides 
Nickel alloys such as 825, 625 and C-276 are more frequently used for their performance in sour gas applications. Of these alloys, 625 and C-276 have demonstrated excellent resistance to Pitting and crevice corrosion of offshore stainless steel Of these alloys, 625 and C-276 have demonstrated excellent resistance to localised corrosion. Ferritic alloys such as Sea-Cure and AL29-4C are resistant to attack by aqueous chloride solutions and are primarily used as heat exchanger tubing. Tungum is a copper-zinc alloy that has been used because of its relative ease of installation. Specification Sheet:Alloy C276 - Stainless Steel, Nickel Alloy C276 (UNS N10276) is an austenitic nickel-molybdenum- chromium alloy with a small addition of tungsten. It is one of the premier corrosion resistant materials available for process industries. Alloy C276 has excellent corrosion resistance in both oxidizing and reducing environments. The combination of the high molybdenum and chromium content, along with the addition of tungsten, make Alloy C276 highly Why is Stainless Steel Corrosion Resistant? - Industrial During the fabrication of stainless steel components or structures it is possible to degrade the corrosion resistance. This occurs when austenitic stainless steels (e.g. 304) are exposed to temperatures between about 425 °C (797 °F) and 870 °C (1598 °F).
