With a firm belief in maintaining high quality and customer satisfaction, the company provides a wide range of fastening solutions as per the diverse industrial requirements. Their top-of-the-line products include Hastelloy C22 Bolts, produced with a high-quality Nickel-Chromium-Molybdenum alloy (UNS N06022). These bolts are available in sizes like hex head, socket head, U-bolts, and anchor bolts. They are renowned for superior corrosion resistance and are specified for application under aggressive chemical and high-temperature conditions.
Hastelloy C22 Bolts are primarily composed of Nickel (56%), Chromium (22%), Molybdenum (13%), and small amounts of Iron, Cobalt, and Tungsten. Mechanically, they offer high strength with a tensile strength of around 690 MPa and a yield strength of approximately 310 MPa, along with an elongation of about 45%. Physically, the material has a density of 8.69 g/cm³ and a melting range between 1399–1410°C. These properties make Hastelloy C22 Bolts highly resistant to pitting, crevice corrosion, and stress corrosion cracking in harsh environments.
