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.
The high-performance nickel alloy used to make Hastelloy C22 Washers is composed of nickel (about 56%), chromium (20–22.5%), molybdenum (12.5–14.5%), iron (2–6%), and trace elements such as carbon, tungsten, and cobalt. It is appropriate for harsh environments because of its composition, which guarantees superior resistance to oxidising and reducing agents. Tensile strength of about 690 MPa, yield strength of about 283 MPa, and elongation of up to 45% are examples of mechanical properties. These washers are a dependable and long-lasting option for demanding applications because they maintain their mechanical integrity in the face of high temperatures and corrosive environments.
Hastelloy C22 washers are frequently utilised in settings where exceptional resistance to corrosion is crucial. Chemical processing, waste treatment, marine engineering, pharmaceuticals, and pollution control systems are examples of common industries. They are utilised in reactors, heat exchangers, pumps, valves, pressure vessels, and other devices where even load distribution and sealing are essential. These washers are particularly useful in settings with oxidising agents, strong acids, and chlorides. They are perfect for long-term use under harsh service conditions because of their resilience to localised corrosion and durability. To satisfy particular application needs, Punit Fasteners provides C22 washers in both standard and customised specifications.
