Alloy Insights: C-276 – The Industry Standard for Corrosion Resistance

At Corrosion Materials, Alloy C-276 (UNS N10276 / W.Nr. 2.4819) is not just another high-performance alloy, it is the foundation of our product offering and the material that built our reputation. In this installment of our Alloy Insights series, we are putting the spotlight on the alloy we know best: a trusted solution for industries that demand the highest level of corrosion resistance.

What Sets Alloy C-276 Apart?

Alloy C-276 is a solid solution strengthened nickel-molybdenum-chromium alloy with a small addition of tungsten. Engineered to withstand extreme chemical environments, Alloy C-276 combines exceptional corrosion resistance with reliable mechanical performance.

One of the most corrosion-resistant materials available today, Alloy C-276 offers superior resistance compared to traditional stainless steels such as 316Lor 904L, and even outperforms other high-performance alloys in environments containing chlorides, strong acids, or mildly oxidizing and reducing acid solutions.

Its capabilities span a wide range of challenging environments, including:

• Strong acids (sulfuric, hydrochloric, formic, acetic)
• Chloride-laden solutions
• Wet chloride gas, chlorine, and hypochlorite
• Seawater exposure, even in crevice conditions

It also offers outstanding resistance to:

• Pitting
• Stress corrosion cracking
• Oxidizing and reducing atmospheres

While Alloy C-276 excels in most environments, it is less suitable for hot, concentrated nitric acid.

Tough, ductile, and highly weldable, Alloy C-276 is a staple across global industries for one reason: it performs where others fail.

Wherever aggressive corrosion is a concern, Alloy C-276 delivers unmatched protection.
