What Makes C276 Material the Go-To Choice for Corrosive Environments?
Are you working in an industry where corrosion is a constant threat? Whether it’s chemical processing, marine environments, or pollution control systems, materials exposed to aggressive media need exceptional durability. C276 Material Composition plays a key role in determining how a material performs under such challenging conditions.
Hastelloy® C-276, commonly known as C276 alloy, is one of the most trusted corrosion-resistant materials in the world. But what exactly makes it so special?
What Is C276 Alloy?
C276 alloy is a nickel-molybdenum-chromium superalloy with the addition of iron and tungsten. It is designed to provide excellent corrosion resistance in a wide variety of severe environments. One of its most significant advantages is its ability to resist the formation of grain-boundary precipitates in the weld-heat affected zone, making it ideal for chemical processing applications.
C276 Material Composition (Typical, % by weight)
Nickel (Ni): Balance
Molybdenum (Mo): 15.0 – 17.0%
Chromium (Cr): 14.5 – 16.5%
Iron (Fe): 4.0 – 7.0%
Tungsten (W): 3.0 – 4.5%
Cobalt (Co): ≤ 2.5%
Manganese (Mn): ≤ 1.0%
Silicon (Si): ≤ 0.08%
Carbon (C): ≤ 0.01%
Vanadium (V): ≤ 0.35%
Phosphorus (P) / Sulfur (S): ≤ 0.03% each
This precise C276 material composition gives the alloy outstanding resistance to oxidizing and reducing agents, even in hot and contaminated mineral acids like hydrochloric acid, sulfuric acid, and nitric acid.
Key Properties of C276 Alloy
Excellent general corrosion resistance
Outstanding performance in highly oxidizing and reducing environments
Exceptional pitting, crevice corrosion, and stress corrosion cracking resistance
Good weldability without post-weld heat treatment
Maintains strength and integrity in high-temperature service
These characteristics make C276 alloy highly suitable for chemical reactors, heat exchangers, scrubbers, evaporators, and flue gas cleaning systems.
Standards and Available Forms
C276 alloy complies with several international standards, including:
ASTM B574 (Bar and Rod)
ASTM B575 (Plate, Sheet, and Strip)
ASTM B619/B622 (Seamless and Welded Pipe)
ASTM B366 (Forgings and Fittings)
At Hangnie Super Alloys, we offer C276 in various product forms, including:
Bars and Rods
Plates and Sheets
Pipes and Tubes
Flanges and Forged Components
Each product is manufactured to tight tolerances and tested to meet the most stringent quality standards.
Why C276 Material Composition Matters
The unique blend of nickel, molybdenum, chromium, and tungsten in C276 allows it to stand up to aggressive media that would degrade or destroy standard stainless steel or lower-grade alloys. For industries like chemical processing, offshore oil & gas, pulp and paper, and pollution control, using a material with the right composition is critical for long-term reliability, safety, and cost-effectiveness.
