Hastelloy C276 Alloy Wire UNS N10276
Professional supplier of C276 high-corrosion-resistant alloy wire, diameter 0.08-3mm, with straightening and cutting customization available.
Material Overview
Hastelloy C276 (UNS N10276) is a nickel-molybdenum-chromium-iron-tungsten alloy renowned for exceptional resistance to severe corrosive media. It delivers outstanding pitting and crevice corrosion resistance in wet chlorine, hypochlorites, chloride solutions, oxidizing salts, and various organic and inorganic acids, making it an ideal material choice for chemical processing and environmental protection applications.
C276 alloy wire is produced via a dual-process method combining vacuum induction melting and electroslag remelting to ensure material purity and microstructural uniformity. The wire features a smooth surface finish and dimensional accuracy of ±0.01mm, meeting the demanding requirements of chemical processing equipment and flue gas desulfurization systems.

Frequently Asked Questions (FAQ)
Which corrosive media can C276 alloy wire withstand?
C276 alloy wire withstands wet chlorine, hypochlorites, chloride solutions, oxidizing salts, hydrochloric acid, sulfuric acid, phosphoric acid, and other highly corrosive media. It offers superior resistance to pitting and crevice corrosion in chloride-containing environments.
What's the difference between C276 and C22?
C276 has higher molybdenum content (15-17% vs 12.5-14.5%), offering better resistance to reducing acids like hydrochloric acid. C22 has higher chromium content (20-22.5% vs 14.5-16.5%), providing superior resistance to oxidizing acids. Choose between them based on the specific medium.
Can C276 alloy wire be welded?
C276 alloy wire can be welded using TIG, MIG, and resistance welding processes. ERNiCrMo-4 filler wire is recommended; preheating is not required before welding, and post-weld heat treatment is generally unnecessary.
What is the maximum operating temperature for C276 wire?
C276 alloy wire maintains excellent corrosion resistance from room temperature up to approximately 400°C. Short-term use is possible at temperatures up to 1000°C, but oxidation rates should be evaluated for long-term high-temperature exposure.
