Hastelloy C276

What is Hastelloy C276?

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.

Hastelloy C276 Forgings

Hastelloy C-276 is one of the most corrosion-resistant steels in the world. This powerful alloy goes beyond the benchmarks notched by its companion Hastelloy grades to include strong resistance across the board to oxidizers such as wet chlorine gas, hypochlorite, and chlorine dioxide. And with the legendary Hastelloy heat resistance, this alloy finds its way into a number of aerospace industrial applications.

Hard to find alloys are no problem here. Whether you are looking for a foreign chemistry or an obsolete blend, All Metals & Forge can usually have it prepared, forged and finished for you far faster than anyone else in the industry. These days, a growing number of clients come here for custom alloys of their own devising–no problem for a team that has helped to create some of the most popular alloys in the business.

Forging Applications

Chemical process equipment and desulfurization of flue gas equipment.


Good machinability, although the alloy work hardens as is true of the nickel base alloys in general.


Can be cold worked by all conventional methods.


Weldable by all common methods except that excessive heat input should be avoided. Can be used in the “as-welded” condition without further heat treatment for most corrosive applications.

Heat Treatment

Solution heat treatment is done at 2050 F followed by a rapid quench. The alloy is supplied in this condition. If hot forming or forging is done then the parts should be solution heat treated, if possible, before use.


The alloy can be forged or hot-upset by conventional means.

Hot Working

Can be hot formed or extruded. Should be solution heat treated following hot forming.

Cold Working

Readily cold worked by conventional methods.


Normally supplied and use in the solution treated condition, a 2050 F soak followed by rapid quench.


Not normally done. The alloy is used in solution treated condition.


Not applicable to this alloy.


Hardened by cold working only.
