Hastelloy C276 Pipe Fittings

Hastelloy C276 pipe fittings are nickel-molybdenum-chromium alloy fittings manufactured to the standards UNS N10276 and Werkstoff 2.4819. The alloy contains approximately 57% nickel, 15-17% molybdenum, 14.5-16.5% chromium, 4-7% iron, and 3-4.5% tungsten, giving it very good resistance to both oxidising and reducing corrosive media. C276 pipe fittings handle pitting, crevice corrosion, and stress corrosion cracking well, even in acidic and chloride-bearing environments. These properties make them suitable for chemical processing, oil and gas systems, pollution control equipment, pharmaceutical manufacturing, and waste treatment plants. Alloy C276 pipe fittings are also referred to as C276 pipe fittings" in procurement and are available in a full range of fitting types and schedules to suit most piping system requirements.

Hastelloy C276 Pipe Fittings Price

The Hastelloy C276 Pipe Fittings price is influenced by several factors. Below are the main pricing aspects to consider before placing an order.

Approximate Price Range

Hastelloy C276 pipe fittings in India are generally available in the range of Rs. 5,250 to Rs. 9,000 per kg for standard configurations. Prices outside this band are common for non-standard sizes, heavier schedules, or low-volume orders.

Factors Affecting Price

The high nickel and molybdenum content in Hastelloy C276 makes it considerably more expensive than standard stainless steel. Both nickel and molybdenum are traded as commodities, and their global prices shift across quarters, which directly affects the per-kg cost of finished fittings. Fitting type matters too. Seamless butt-weld elbows and tees carry different rates compared to socket-weld or threaded types. The cost is affected by the heavier wall schedules, such as SCH 160 or XXS, requiring more material and more machining. Other factors include order quantity, surface treatment, heat treatment condition, third-party inspection requirements, and freight. Sourcing from a supplier offering traceable mill test certificates may cost slightly more upfront, but it reduces procurement risk considerably.

How To Choose The Right Hastelloy C276 Pipe Fittings Supplier and Manufacturer?

Sourcing Hastelloy C276 pipe fittings from the right supplier involves more than comparing prices. A few practical checks are worth doing before placing any order.

Selecting The Right Supplier and Manufacturer

Start by confirming the supplier can provide material to ASTM B366 / ASME SB366 with valid mill test certificates traceable to UNS N10276. Not all distributors carry genuine Hastelloy C276; asking for chemical analysis reports with heat and lot numbers is a basic but necessary step. The hastelloy C276 pipe fitting suppliers with a consistent track record in chemical processing or oil and gas projects tend to be more reliable in documentation and delivery timelines.

Technical Considerations

Confirm the availability of type, size, and wall schedule before ordering. In certain arrangements, special heat treatment, special end preparations, or third-party inspection may be required. If the dimensions are not standard, ask the supplier if they can make it in-house or if it will take longer to get from the mill or processor.

Evaluating Supplier Credibility

Look to see if the supplier carries inventory or is a trader. Smaller orders for higher inventory turn and lower risk of substitutions from stocking suppliers. Check ISO 9001 and, if applicable, NACE or PED. Mill test certificates should be stamped by the manufacturer and traceable to the original production lot.

Procurement Strategy

If you have a great or recurring demand, a rate contract may help you secure stable pricing and a steady supply. For smaller or project-specific purchases, shop around for quotations from multiple Hastelloy C276 pipe fittings suppliers and consider freight, testing, certification, and delivery schedules, as well as the per-kilogram price.
