What is ASTM B575 UNS N10276 Sheet?
UNS N10276 (Hastelloy C-276) is a low-carbon corrosion-resistant alloy based on nickel. It complies with the ASTM B575 standard, covering the chemical composition, mechanical properties, tolerances and processing requirements of its plates and sheets.
Hastelloy C-276 plates perform better than 316L and 904L stainless steels in wet chlorine, hypochlorite and ferric chloride solutions, and have an oxidation resistance temperature of up to 1100°C, making them suitable for high-temperature and high-pressure equipment16. Although more expensive than ordinary stainless steel, their long life and low maintenance costs make them more economical in harsh environments

FAQ
Q: What is the price of C-276 alloy plate? How is it different from 316L stainless steel?
Price range: about 5–8 times that of 316L stainless steel (due to the high proportion of nickel, molybdenum, and tungsten).
Cost advantage: It can significantly reduce maintenance costs in highly corrosive environments and has a lifespan 3–5 times longer than 316L.
Q: Does C-276 alloy plate require maintenance?
Daily maintenance:
Avoid long-term contact with acidic/halide solution residues;
Clean the surface regularly with a neutral detergent to prevent the accumulation of pollutants;
The welding area needs to be checked for signs of stress corrosion cracking.
