Elvis Nickel Alloys, a top-notch manufacturer and supplier based in Houston, USA, specializes in precision-engineered Hastelloy Screws that excel in harsh, corrosive, and high-temperature settings. Crafted from premium Hastelloy alloys like C22, C276, and B2, these screws offer exceptional resistance to oxidation, pitting, and stress corrosion cracking. They come in various styles—including hex head, socket head, countersunk, and machine screws—and comply with international standards such as ASTM B574 and DIN/ISO specifications. Trusted across critical industries like chemical processing, marine, aerospace, pharmaceuticals, and power generation, Hastelloy Screws are synonymous with reliability and durability.
Hastelloy Screws are primarily made of nickel (≥57%), with notable amounts of molybdenum (15–17%), chromium (14–22%), and trace elements like iron, cobalt, and tungsten, depending on the specific grade. This unique blend provides excellent resistance to chloride-induced corrosion, acids, and oxidizing agents. Their mechanical properties boast a tensile strength of up to 690 MPa, yield strength ranging from 280 to 350 MPa, and impressive elongation (≥40%), making them perfect for both static and dynamic loads. These screws perform reliably across a wide temperature spectrum, ensuring dependable fastening solutions in both cryogenic and high-temperature environments.
