The Fasteners Mart, situated in Mumbai, India, is a reliable manufacturer and exporter of high-quality industrial fasteners to a global customer base. Prioritizing quality and strength, the company supplies a variety of fasteners for different industrial applications. Among its high-quality products is the Hastelloy C22 Fasteners, which are produced using Nickel-Chromium-Molybdenum alloy (UNS N06022). These fasteners come in different forms like bolts, nuts, screws, studs, and washers. These are renowned for having very good corrosion resistance and hence are suitable for harsh and chemically aggressive conditions.
Hastelloy C22 Fasteners consist of primarily Nickel (about 56%), Chromium (22%), Molybdenum (13%), and Iron (3%), with small traces of Cobalt and Tungsten. They are highly mechanically strong with a tensile strength of nearly 690 MPa and yield strength of 310 MPa, providing nearly 45% elongation. They are physically characterized by their density of 8.69 g/cm³ and melting point of 1399–1410°C. These characteristics render them extremely reliable in harsh temperatures and corrosive environments, guaranteeing superior performance in demanding applications.

To satisfy our clients needs by providing high quality products at competitive price as per the schedule and to maintain long term relationship with our clients.
Hastelloy C22 Fasteners are used extensively in chemical processing, marine, pharmaceutical, and pollution control industries. Due to their resistance to pitting, crevice corrosion, and oxidizing/reducing environments, they are suitable for equipment such as heat exchangers, pressure vessels, and reactors. These fasteners are particularly ideal for application in acidic environments, i.e., sulfuric, hydrochloric, and nitric acids. They also perform well in scrubbers, flue gas cleaning systems, and waste treatment plants. Their durability and dependability make them critical to the maintenance of the integrity of high-stress, high-risk systems.
The Hastelloy C22 Fasteners are provided with timely and consistent delivery facilities by Fasteners Mart across the globe. Products are individually wrapped in wooden cases, cartons, or according to client specifications in order to provide secure transportation.
