Hastelloy C276 Seamless Pipe ASTM B622 UNS N10276 6m Length for Chemical Reactor Heat Exchanger Applications

Hastelloy C276 Seamless Pipe

Our Hastelloy C276 (UNS N10276) seamless pipes are manufactured to ASTM B622/ASME SB622 standards. As the most widely used nickel-molybdenum-chromium wrought alloy, Hastelloy C276 delivers unparalleled resistance to a broad range of aggressive chemicals, including both oxidizing and reducing acids, making it the premier choice for the most severe chemical processing environments.

Key Features

• ✓Universal Corrosion Resistance: Exceptional resistance to both oxidizing media (ferric/ cupric chlorides, chlorine, wet chlorine) and reducing environments (sulfuric, hydrochloric, phosphoric acids), unmatched by most other alloys.
• ✓SCC & Pitting Resistance: Virtually immune to chloride-induced stress corrosion cracking (SCC) and offers outstanding resistance to pitting and crevice corrosion (PREN > 50).
• ✓Excellent Weldability: Resists intergranular attack in the as-welded condition, eliminating the need for post-weld heat treatment in most applications.
• ✓NACE MR0175 Compliant: Certified for sour service applications in H2S-containing environments per NACE MR0175/ISO 15156 standards.
