Hastelloy alloys comprise a family of nickel-based superalloys renowned for their exceptional resistance to a broad spectrum of corrosive media, making them indispensable in the most challenging industrial environments. These alloys—including Hastelloy C-276, C-22, and B-3—are engineered with precise combinations of nickel, molybdenum, chromium, and other elements to address specific corrosion challenges. Newstar Hardware offers Hastelloy products in various forms, each tailored to unique applications: Hastelloy C-276 (UNS N10276) withstands strong acids and chlorides, ideal for chemical processing and flue gas desulfurization; Hastelloy C-22 (UNS N06022) offers improved resistance to oxidizing acids and pitting; Hastelloy B-3 (UNS N10675) excels in reducing acid environments like hydrochloric acid processing. Manufactured to ASTM B574, B575, and B622, these alloys exhibit tensile strengths from 730 MPa to 1,000 MPa, with elongation up to 40%, enabling complex fabrication. Their ability to resist both oxidizing and reducing agents, high-temperature scaling, and stress corrosion cracking positions Hastelloy alloys in critical sectors like pharmaceuticals, nuclear energy, and marine engineering. Custom machining and heat treatment services ensure components meet exacting specifications, while rigorous quality control guarantees reliability in life-critical applications.
