- Hastelloy Forged Fittings
Hastelloy forged fittings are high-strength pipe fittings made from corrosion-resistant nickel alloys, built to handle extreme conditions. Midland Alloys is a trusted Hastelloy forged fittings manufacturer in India, offering a full range of grades like Hastelloy C276, C22, and B2 in types such as socket weld and threaded fittings with various surface finishes. These fittings are manufactured using forging techniques, where high-pressure and heat form solid, grain-refined components for better strength and durability. We produce fittings from 1/8″ NB to 4″ NB, strictly following the ASTM B564 and ASME SB564 specifications. Each fitting is carefully processed, heat-treated, and tested to ensure consistent performance and a long service life. Our forged fittings meet ANSI B16.11 requirements and are shipped worldwide. We offer a variety of types, including socket welds, threaded, tees, split, elbows, change direction, couplings, plugs, and caps seal ends. With years of experience and international customers, we guarantee the quality, accuracy, and fast delivery of certified Hastelloy fittings.
Benefits of Hastelloy Socket Weld Forged Fittings
Hastelloy socket weld forged fittings are known for their strength and performance in harsh conditions. Here’s why engineers prefer forged Hastelloy fittings:
- Exceptional Corrosion Resistance: Hastelloy alloy forged fittings can handle acids, chlorides, and seawater without breaking down
- High-Temperature Performance: They work well in heat-intensive environments like reactors, furnaces, and exhaust systems
- Resistance to Stress Corrosion Cracking: These fittings resist cracking caused by chloride-rich or high-stress environments
- Strength and Toughness: The forging process boosts strength while keeping the fittings tough and reliable under pressure
- Durability: They have a long life cycle and need less maintenance, even in aggressive setups
Hastelloy alloy forged fittings offer better corrosion resistance in acidic environments, especially where there’s hydrochloric or sulfuric acid. They are useful for chemical processing and marine environments. In contrast, Inconel forged fittings are better for high heat and oxidation, making them more frequent in aerospace, and heat-treating installations. While both are nickel-based alloys, Hastelloy handles aggressive chemical attacks better whereas Inconel performs well at elevated temperatures under stress.

Types of Hastelloy 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.
