Hastelloy Tubing

Hastelloy Tubing

Hastelloy tubing is a hollow cylindrical product manufactured from nickel-based superalloys, available in various grades, such as C276, C22, C4, B2, B3, B4, X, N, and C2000 and 2 primary types: seamless and welded. The alloy composition typically includes 40–60% nickel combined with molybdenum, chromium, and cobalt, delivering outstanding resistance to uniform corrosion, pitting, and stress-corrosion cracking. 3 key benefits make Hastelloy tubing the preferred choice in critical applications: superior corrosion resistance in oxidising and reducing environments, high temperature stability up to 1093°C, and long service life with reduced maintenance costs. It is widely specified in chemical processing, oil and gas, aerospace, pharmaceuticals, and power generation industries.

Hastelloy Tubing Prices

Hastelloy tubing prices depend on the grade, size, production method, and order volume. Understanding the cost structure enables engineers and procurement teams to plan budgets accurately.

Approximate Price Range

Hastelloy tubing is priced between Rs. 4,200 and Rs. 7,200 per kg for standard grades and schedules. Grades with higher molybdenum and chromium content, such as C276 and C22, command higher rates due to raw material complexity.

Factors Affecting Price

4 key variables drive the final cost of Hastelloy tubing:

  • Grade and alloy content: Higher nickel-molybdenum grades, such as C276, cost more than standard grades due to the added alloying complexity.
  • Wall thickness and schedule: Thicker walls consume more material per metre, increasing cost per kilogram.
  • Manufacturing method: Seamless Hastelloy tubing carries a higher price than welded (ERW) due to tighter dimensional tolerances and lower production volumes.
  • Market fluctuations: Base rates follow commodity nickel and molybdenum prices. Always confirm current pricing before placing bulk orders.

Hastelloy Tubing Grades

Grade selection is based on the operating temperature, corrosive medium, and mechanical load requirements. The 9 available grades are listed below.

How To Choose The Right Hastelloy Tubing Supplier And Manufacturer?

Choosing the right Hastelloy tubing supplier directly affects tubing integrity, project timelines, and total procurement cost. Evaluate these 4 areas before finalising a vendor.

Selecting The Right Supplier And Manufacturer

Confirm the manufacturer produces Hastelloy tubing in the exact grade and NPS required. Not every facility handles all 9 grades. Verify production capabilities before issuing an RFQ.

Technical Considerations

Match the grade to the service environment, like acidic media, oxidising conditions, or elevated-temperature service. Request a Material Test Certificate (MTC) confirming chemical composition and mechanical properties. Confirm compliance with ASTM B622 or ASTM B626 as applicable. Custom wall schedules carry 8–12 week lead times; check stock availability early.

Evaluating Supplier Credibility

A credible Hastelloy tubing supplier holds ISO 9001 certification at a minimum. Every tube batch must carry a heat number traceable to the originating mill. This is essential for project documentation and quality audits.

Procurement Strategy

Send a clear RFQ that includes grade (UNS number), NPS, wall schedule, finish, governing standard, and order quantity. Evaluate at least three supplier proposals based on pricing, lead time, MTC availability, and minimum order quantities. For bulk orders, plan a pre-dispatch inspection (PDI) or third-party inspection (TPI) at the facility.

Hastelloy Tubing FAQ's

Hastelloy tubing is used in chemical processing lines, oil and gas downhole equipment, aerospace hydraulics, pharmaceutical reactors, heat exchangers for power production and marine applications. The nickel-molybdenum-chromium alloy can survive hydrochloric acid, sulphuric acid, oxidising media, and high-temperature service conditions that stainless steel cannot.

Hastelloy tubing is priced between Rs. 4,200 and Rs. 7,200 per kg for standard grades and schedules. The final rate depends on grade, outside diameter, wall schedule, and order volume. The grades such as C276 and C22 command higher rates due to elevated molybdenum and chromium content.

The pressure rating varies with grade, NPS, and wall schedule. Working pressure is calculated using ASME B31.3 and the grade's allowable stress value at operating temperature. A Hastelloy C276 tube in Sch-80 NPS 1" sustains significantly higher pressure than its Sch-10 counterpart at the same temperature.

Hastelloy tube specifications adhere to ASTM B622 for seamless tubing and ASTM B626 for welded tubing. Other relevant standards comprise ISO 6207 and DIN 17751. Dimensional specifications adhere to ASME B36.19M for standard schedules. Compliance with chemical and mechanical standards is confirmed via MTC documentation.

Wall thickness ranges from 0.40 mm to 15.0 mm, depending on NPS and schedule. A 2" NPS tube in Sch-80 carries a significantly thicker wall than the same tube in Sch-10. Refer to the size and schedule charts above for the full range across available schedules and outside diameters.
