HASTELLOY C-276 alloy (UNS N10276) was the first wrought, nickel-chromium-molybdenum material to alleviate concerns over welding (by virtue of extremely low carbon and silicon contents). As such, it was widely accepted in the chemical process and associated industries, and now has a more than 50-year-old track record of proven performance in a vast number of corrosive chemicals.

Resistance to Pitting and Crevice Corrosion
HASTELLOY C-276 alloy exhibits high resistance to chloride-induced pitting and crevice attack, forms of corrosion to which the austenitic stainless steels are particularly prone. To assess the resistance of alloys to pitting and crevice attack, it is customary to measure their Critical Pitting Temperatures and Critical Crevice Temperatures in acidified 6 wt.% ferric chloride, in accordance with the procedures defined in ASTM Standard G 48. These values represent the lowest temperatures at which pitting and crevice attack are encountered in this solution, within 72 hours. For comparison, the values for 316L, 254SMO, 625, and C-276 alloys are as follows:
| Alloy |
Critical Pitting Temperature in Acidified 6% FeCl3
|
Critical Crevice Temperature in Acidified 6% FeCl3

| °F | °C | °F | °C | |

| 254SMO | 140 | 60 | 86 | 30 |
| 625 | 212 | 100 | 104 | 40 |
| C-276 | 302 | 150 | 131 | 55 |
