Located in Delhi, India, Harshita Stainless is a well-known producer and supplier of stainless steel 422 fasteners, providing strong and heat-resistant fastening solutions for demanding industrial applications. SS 422 fasteners are well-known for their remarkable resistance to oxidation and high-temperature strength, making them perfect for use in harsh mechanical and thermal environments. Bolts, nuts, washers, studs, and other precisely engineered fasteners that satisfy international quality standards are supplied by Harshita Stainless. Serving industries like engineering, petrochemical, power generation, and aerospace, the company is dedicated to performance, durability, and on-time delivery while providing dependable fastening solutions for demanding high-stress applications.
With iron serving as the base, the main constituents of stainless steel 422 fasteners are chromium (11–13%), molybdenum (~1%), tungsten (~1%), and carbon (0.20–0.25%). This martensitic stainless steel has a high creep and oxidation resistance and is made for applications requiring high temperatures. Mechanically, SS 422 provides good toughness following heat treatment, tensile strength of 760–1040 MPa, and yield strength of 550–750 MPa. These fasteners are appropriate for high-stress, high-temperature settings that demand long-term performance because they can be heat-treated to harden them and maintain their mechanical qualities up to 600°C.

In high-temperature, high-stress applications where robustness and thermal stability are essential, stainless steel 422 fasteners are frequently utilised. They are used in jet components, exhaust systems, and turbine engines in the aerospace sector. Because of their resistance to oxidation and creep, power plants use them in heat exchangers, boilers, and steam turbines. Reactors, pressure vessels, and high-heat piping systems in petrochemical facilities are all reliably supported by SS 422 fasteners. They also work in the automotive, industrial machinery, and defence industries. They are essential for fastening components under harsh service conditions because of their resistance to thermal cycling and mechanical loads.
