Elvis Nickel Alloys, a top-notch manufacturer and supplier located in Houston, USA, provides an impressive selection of Hastelloy Nuts that are engineered to offer exceptional strength and corrosion resistance, even in the toughest industrial environments. Crafted from high-performance nickel alloys like Hastelloy C22, C276, and B2, these nuts are perfect for critical fastening tasks where resistance to oxidizing, reducing, and chloride-rich conditions is a must. They come in various shapes, including hex, heavy hex, lock, and custom designs, all adhering to international standards like ASTM B574 and ASME B18.2.2. Hastelloy Nuts find extensive applications in the chemical processing, marine, nuclear, and pharmaceutical sectors.
Hastelloy Nuts generally consist of nickel (≥57%), molybdenum (15–17%), chromium (14–22%), along with trace amounts of iron, cobalt, and tungsten, which can vary slightly by grade (C22, C276, B2). These components provide the nuts with remarkable resistance to pitting, crevice corrosion, and stress corrosion cracking. Their mechanical properties boast a tensile strength of up to 690 MPa, yield strength around 283 MPa, and an elongation exceeding 40%, ensuring robust and durable performance even under thermal and chemical stress. Hastelloy maintains its structural integrity across a wide temperature range, making it ideal for extreme service conditions.
