Apr 1, 2022 · C-22 Hastelloy (UNS N06022): C-22 Hastelloy consists of 58% nickel, 20% chromium, 13% molybdenum, 3.5% tungsten, 2.5% cobalt, and traces of other elements. Widely known for its weldability, the C-22 Hastelloy is the most used alloy for pharmaceutical reaction vessels and desulfurization systems.

The most widely used and versatile Hastelloy alloys are the C-types. Formulated in 1952, the Hastelloy X alloy is a more recent grade of superalloy compared to others. It contains higher percentages of iron to improve oxidation resistance, formability, and high temperature strength.

Hastelloy C-4. Hastelloy C-4 is corrosion resistant to chloride-containing oxidation or reduction. It features good thermal stability, suitable for wet chlorine, hypochlorous acid, sulfuric acid, hydrochloric acid, mixed acid, chloride device and direct application after welding.

Hastelloy C Types. While Hastelloy B types and Hastelloy C types are both able to resist oxidizing and reducing environments at high temperatures (1,400°F/760°C – 2,000°F/1,094°C), Hastelloy C has the added ability to carry heavy loads at temperatures of up to 1,600°F/871°C.

Hastelloy alloys, epitomized by Grade C-22 and C-276, are pivotal in diverse industrial domains due to their unparalleled corrosion resistance. In sectors spanning chemical processing, oil and gas refining, power generation, and aerospace manufacturing, these …

May 21, 2020 · Hastelloy C-22 alloy is a QUAN capable nickel-chromium-molybdenum-tungsten alloy, which has better overall corrosion resistance than other existing nickel-chromium-molybdenum alloys, including Hastelloy C-276, C4 alloy and 625 alloy. Hastelloy C-22 alloy has good resistance to pitting corrosion, crevice corrosion and stress corrosion cracking.
