Hastelloy C-276 is a nickel-molybdenum-chromium-tungsten alloy with excellent general corrosion resistance and good fabric ability. 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.

GENERAL INFORMATION :

• Principal Design Features :
  C-276 is a wrought corrosion-resistant alloy. A prime advantage of this alloy is that it generally does not require solution heat treatment after welding. It resists the formation of grain boundary precipitates that would degrade corrosion resistance.
• Applications :
  Chemical process equipment and desulfurization of flue gas equipment.
