Hastelloy C276 Fasteners are engineered from an alloy blend of nickel, molybdenum, chromium, tungsten, and iron. This distinctive amalgamation endows the material with exceptional attributes, including unparalleled corrosion resistance across a spectrum of acidic environments. ASTM B574 UNS N10276 Fasteners exhibit remarkable resilience against pitting and crevice corrosion, even when subjected to warm chloride-containing solutions such as seawater. Moreover, their superior fabricability compared to alternative options can substantially lower production costs, rendering them a cost-effective choice for various industrial applications.
Hastelloy C276 Fasteners stand out as optimal choices for high-performance applications owing to their robustness and longevity. With the ability to endure an extensive temperature range from -400°F to +1200°F, they exhibit remarkable corrosion resistance across diverse environments. Available in various forms such as Hastelloy C276 Nuts, Hastelloy C276 Bolts, and more, these fasteners cater to a broad spectrum of industrial needs. Industries including chemical processing, power generation, oil refining, marine engineering, aerospace manufacturing, and beyond benefit significantly from their exceptional properties and versatility.
