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.
Machinability Good machinability, although the alloy work hardens as is true of the nickel base alloys in general.
Forming Can be cold worked by all conventional methods.
Corrosion Resistance Very good corrosion resistance to oxidizing and reducing acids. The alloy also has excellent resistance to stress-corrosion cracking and to pitting, as well as being very resistant to chlorine gas or compounds corrosion. Boiling HCl acid (2% concentra
Welding 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.
Forging 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.
Annealing Normally supplied and use in the solution treated condition, a 2050 F soak followed by rapid quench.
Aging Not normally done. The alloy is used in solution treated condition
Tempering Not applicable to this alloy.
Hardening Hardened by cold working only, but normally used in the solution annealed condition.
