ASME SB622 Hastelloy C276 pipe
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.
Hastelloy C-276 is balanced to provide excellent corrosion resistance to a variety of chemical process environments. This alloy has provided resistance to hot contaminated mineral acids, organic and inorganic chloride contaminated media, hypochlorite, chlorine dioxide solutions, formic and acetc acids, acetic anhydride, sea water and brine solutions.

*Determined in laboratory tests. It is recommended that samples be tested under actual plant conditions.
**Solution heat-treated
***Gas tungsten-arc welded.
Hastelloy C-276 can be forged, hot-upset, and impact extruded. Although the alloy tends to work-harden, it can be successfully deep-drawn, spun, press formed or punched. All of the common methods of welding can be used to weld alloy C-276, although the oxy-acetylene and submerged arc processes are not recommended when the fabricated item is intended for use in corrosion service. Special precautions should be taken to avoid excessive heat in-put.
Welding
Gas tungsten-arc welding, gas metal-arc welding, shielded metal-arc (coated electrode) welding, or resistance welding may be used. Minimum heat input consistent with adequate penetration reduces the chance of hot-cracking. Oxyacetylene welding should be avoided due to possibility of carburization. Hastelloy C-276 can be used in the as-welded condition in most chemical and petrochemical process equipment.
Wrought forms of Hastelloy C-276 are furnished in the solution heat-treated condition unless otherwise specified. Alloy C-276 is normally solution heat-treated at 2050 °F and rapid quenched. Parts which have been hot-formed should be solution heat-treated prior to final fabrication or installation, if possible.
