Frequently Asked Questions

What is Hastelloy C276 and why is it used in valves?

Hastelloy C276 (UNS N10276) is a nickel-molybdenum-chromium superalloy with outstanding corrosion resistance to a wide range of aggressive chemicals. It is used in valves for chemical processing, pharmaceutical, and offshore applications where standard stainless steels fail due to pitting or stress corrosion cracking.

What is the price range for Hastelloy valves?

Hastelloy valves typically cost 8-15x more than equivalent WCB carbon steel valves due to the high cost of raw material and specialized machining. A 2" Class 150 Hastelloy C276 ball valve may range from $2,000 to $5,000 depending on design and quantity. Contact us for project-specific pricing.

Can you supply Hastelloy valves with NACE MR0175 compliance?

Yes. Supreme Valves manufactures Hastelloy C276 and C22 valves fully compliant with NACE MR0175 / ISO 15156 for sour service applications. All valves are supplied with material test certificates (MTC 3.1) and can include third-party inspection.

What sizes and pressure classes are available?

We manufacture Hastelloy valves from 1/2" to 24" in ASME Class 150 through Class 2500. Socket weld, threaded (NPT/BSP), and flanged end connections available. Custom sizes and ratings on request.
