Apr 1, 2022 · Grade C Hastelloy metal is the most widely used Hastelloy material. Common C-type Hastelloy materials are: C-4 Hastelloy (UNS N06455): Type C-4 Hastelloy contains 60% nickel, 18% chromium, 16% molybdenum, 3% iron, 2% Cobalt, and remaining silicon, carbon, sulfur, titanium, etc.

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 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.

Nov 7, 2023 · Hastelloy represents a family of alloys known for their corrosion resistance. Among the Hastelloy family, both C-22 and C-276 exist, and their similarity can be confusing. However, C-22 boasts superior overall corrosion resistance compared to C-276 and is often considered an upgrade from C-276.

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.

May 16, 2024 · Hastelloy is a nickel-based corrosion-resistant alloy, which is mainly divided into two categories: nickel-chromium alloy and nickel-chromium-molybdenum alloy. Hastelloy has good corrosion resistance and thermal stability, and is mostly used in aviation and chemical fields.

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.

Jan 13, 2025 · Hastelloy metals and alloys are known for their excellent corrosion resistance and versatility, making them essential materials for various industries. This guide comprehensively introduces Hastelloy, including its types, properties, applications, and more.
