ASTM B575 Hastelloy C22 & C276 Nickel Alloy Plate and Sheet
ASTM B575 Hastelloy C22 & C276 nickel alloy plate and sheet are specified when components must withstand some of the most aggressive chemical and high-temperature process environments in service. These ASTM B575 flat-rolled products 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 B575 in the main flat-rolled product forms required for fabrication, welding, and vessel construction.
Hastelloy C276 and C22 sheet per ASTM B575 is typically available in thicknesses from 0.002″ to 0.150″, suitable for linings, ducting, bellows, and formed components exposed to severe corrosion.
Hastelloy C276 and C22 plate per ASTM B575 is typically available in thicknesses from 0.1875″ to 5.50″, used for reactors, columns, scrubbers, tanks, and structural parts in harsh chemical environments.
What is ASTM B575 Hastelloy?
ASTM B575 is the standard specification covering nickel-molybdenum-chromium and nickel-molybdenum-chromium-tungsten alloys, including C276 (UNS N10276) and C22 (UNS N06022), supplied as plate, sheet, and strip.
Specifying this ASTM B575 nickel alloy standard ensures that plate and sheet 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 ASTM B575 Hastelloy plate and sheet for critical service.
Specifications
Hastelloy C276 to ASTM B575
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 B575
Hastelloy C22 (UNS N06022) is one of the most versatile nickel-chromium-molybdenum-tungsten alloys, with tightly controlled iron content. As plate and sheet produced to ASTM B575, C22 provides outstanding resistance.
Certified Material for Critical Service
All material produced to ASTM B575 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 B575 plate and sheet into broader nickel-alloy and stainless-steel packages for your project.
