Hastelloy C-276 is a nickel-molybdenum-chromium-tungsten alloy with excellent general corrosion resistance and good fabricability. The alloy should be considered for use in environments where resistance to hot contaminated mineral acids, organic and inorganic chloride-contaminated media, chlorine, formic and acetic acids, acetic , acetic anhydride, sea water and brine solutions is desired.
Hastelloy C-276 has resisted the formation of grain boundary precipitates in the weld heat-affected zone, making it a candidate for most chemical and petrochemical processing applications in the as-welded condition. The alloy has resisted both general and localized corrosion, including pitting, crevice corrosion, and stress corrosion cracking.
Hastelloy C-276 is readily fabricated by welding, using methods similar to those utilized for nickel-based alloys.
At Jiangsu HYT, we are your direct Inconel metal supplier. We provide custom work, short lead times, and quick delivery for all types of large or small quantities of Hastelloy C276 shapes including tube, pipe, wire, sheet, and plate. We are also ISO Certified and provide advanced design expertise for all your Hastelloy C276 alloy needs.
