- Hastelloy C276 Forged Fittings
Hastelloy C276 Forged Fittings are high-performance components made from nickel-molybdenum-chromium alloy designed to withstand aggressive chemical environments. These fittings offer excellent resistance to pitting, stress corrosion cracking, and strong oxidizers. Midland Alloys is a trusted name and leading Hastelloy UNS N10276 forged fittings supplier with years of experience in delivering high-quality products that meet global standards like ASTM B366, ASTM SB366, and ASTM B564. We offer a variety of fittings, including socket-weld, threaded, elbows, tees, couplings, and more. Each kind has a specific purpose in high-pressure piping systems, and is available in a variety of surface treatments and customized sizes. Nickel Alloy C276 forged fittings are highly durable and chemically resistant making them appropriate for demanding process conditions.
Benefits of High-Nickel C276 Forged Fittings
Hastelloy C276 seamless forged fittings deliver unmatched performance in demanding environments. Here’s what makes them a great choice:
- High Strength: Built to handle high pressure and heavy stress without cracking
- Excellent Corrosion Resistance: Hastelloy C276 socket-weld forged fittings work well in acidic, oxidizing, and reducing environments
- Improved Structural Integrity: Maintains form and function over long-term use
- Good Weldability: Easy to join with other metals without compromising quality
- Resistance to Stress Corrosion Cracking: Ideal for aggressive chloride-containing environments
Both Nickel alloy C276 forged fittings and Hastelloy B2 offer excellent resistance to corrosion, but they differ in chemical behavior and application range. High-nickel C276 forged fittings resist a wide spectrum of acids, including oxidizing agents like ferric and cupric chlorides, as well as wet chlorine gas and hypochlorite. They are suitable for both oxidizing and reducing environments, which makes them more versatile. In contrast, Hastelloy B2 forged fittings work best in strictly reducing conditions like anhydrous hydrochloric acid but may fail in oxidizing media. While both are Hastelloy super-alloy forged fittings, C276 has a broader application scope across chemical, marine, and environmental systems, whereas B2 is more limited to highly specific conditions.

Types of Hastelloy C276 Forged Fittings
Manufacturing Types
-
Threaded Forged FittingsDesigned with internal or external threads, these fittings allow quick assembly and disassembly without welding.
-
Socket Weld Forged FittingsThese fittings are joined by inserting the pipe into a recessed area of the fitting and welding around it, ensuring strong, leak-proof joints.
-
Screwed FittingsSimilar to threaded types, screwed fittings are connected using screw threads, making installation simple and cost-effective.
-
BSPTBushings help reduce the bore size in a fitting or valve connection by joining pipes of varying diameters.
-
NPTEnd caps are used to seal a pipeline's end, shielding it from impurities and guaranteeing closed systems' safety.
Forms
-
Forged ElbowElbows, which come in 45° and 90° varieties shift the direction of flow with little pressure loss.
-
Forged BushingBushings help reduce the bore size in a fitting or valve connection by joining pipes of varying diameters.
-
Forged TeeUsed to split or combine flow across three directions essential for branching pipeline.
-
Forged CouplingOffer a safe connection between two pipes; threaded and socket-welded options are available.
-
Forged PlugClose open pipe ends which are frequently used for isolation or testing.
-
Forged CrossWith four openings, cross fittings help connect four pipes used when fluid distribution needs to occur in multiple directions.
