Hastelloy C-22 Round Bar (ASTM B574) Superior Pitting/Crevice Corrosion Resistance, High Strength & Durability

Overview

Hastelloy C-22® is a versatile nickel-chromium-molybdenum-tungsten alloy renowned for its exceptional resistance to a wide range of corrosive environments. Our Hastelloy C-22 round bars, manufactured in strict accordance with ASTM B574 standards, offer superior performance where high strength, outstanding durability, and maximum corrosion resistance are critical. This alloy is the premier choice for handling the most aggressive chemical process and industrial applications.

Key Features & Benefits

• Superior Pitting & Crevice Corrosion Resistance: Hastelloy C-22 provides excellent resistance to localized corrosion, including pitting and crevice attack, in challenging environments containing chlorides and other halogens. This makes it ideal for use in acidic, saline, and oxidizing media.

• Exceptional Overall Corrosion Resistance: The alloy demonstrates outstanding performance against a vast array of corrosive threats, including:

  • Oxidizing acids (e.g., nitric acid, chromic acid)

  • Reducing acids (e.g., hydrochloric acid, sulfuric acid)

  • Mixed Acid Solutions (e.g., HNO₃/HF)

  • Wet Chlorine and Chlorine Gas

• High Strength & Durability: Hastelloy C-22 retains its mechanical integrity and high strength over a wide temperature range, from cryogenic conditions up to high-temperature service. It offers excellent structural durability under mechanical and thermal stress.

• Excellent Fabricability: This alloy can be readily fabricated and welded using standard techniques, allowing for the manufacture of complex components and structures without compromising its corrosion-resistant properties.
