ASTM B574 Hastelloy C22 & C276 Nickel Alloy Round Bar and Forgings
ASTM B574 nickel alloy round bar and forgings in Hastelloy C22 & C276 are specified when components must withstand some of the most aggressive chemical and high-temperature process environments in service. These ASTM B574 bars and forgings from Fighter Jet Metals are supplied for demanding corrosion-resistant applications in chemical processing, pollution control, oil & gas, and power generation.
These nickel-molybdenum-chromium alloys are selected when austenitic stainless steels and standard nickel alloys are no longer sufficient, especially in mixed-acid, chloride, and high-temperature process conditions where localized attack, crevice corrosion, and stress-corrosion cracking are a concern.
Product Forms & Size Range
Fighter Jet Metals supplies C22 and C276 produced to ASTM B574 in the primary long-product forms needed for machining, forging, and final component manufacture.
Hastelloy C276 and C22 per ASTM B574 round bar diameters range from 0.125″ to 14.00″ diameter.
What is ASTM B574 Hastelloy?
ASTM B574 is the standard specification covering nickel-molybdenum-chromium and nickel-molybdenum-chromium-tungsten alloys, including C276 (UNS N10276) and C22 (UNS N06022), supplied as rod, bar, wire, forgings, and forging stock.
Specifying this ASTM B574 nickel alloy standard ensures that bar and forgings are produced and tested to a recognized global standard for high-integrity chemical-process and corrosion-resistant equipment. The specification controls chemistry, melting practice, mechanical properties, and required testing so that designers and end users can confidently select this nickel alloy bar for critical service.
Specifications
Hastelloy C276 to ASTM B574
Hastelloy C276 (UNS N10276) is an austenitic nickel-molybdenum-chromium alloy with a small addition of tungsten, developed for exceptional resistance to pitting, crevice corrosion, and stress-corrosion cracking in both oxidizing and reducing environments.
Hastelloy C22 to ASTM B574
Hastelloy C22 (UNS N06022) is one of the most versatile nickel-chromium-molybdenum-tungsten alloys, with tightly controlled iron content. As bar and forgings produced to ASTM B574, C22 provides outstanding resistance.
Certified Material for Critical Service
All material produced to ASTM B574 from Fighter Jet Metals is supplied with full test reports, heat numbers, and traceability, and can be aligned with additional project or OEM requirements where specified.
On request, we can coordinate dual certification with related standards and integrate ASTM B574 bar and forgings into broader nickel-alloy and stainless-steel packages for your project.
