Harshita Stainless serves a broad range of industries including petrochemical, power generation, and furnace manufacturing. The company guarantees dependable product availability and prompt delivery throughout India by emphasising performance, durability, and customer satisfaction. Their 310S fasteners offer unmatched resistance to heat, scaling, and oxidation—ideal for critical structural and mechanical connections.
The high-temperature austenitic alloy used to make stainless steel 310S fasteners has a low carbon content (≤0.08%) to enhance weldability and resistance to sensitisation, and it contains 24–26% chromium and 19–22% nickel. Up to 1100°C (2012°F), these fasteners retain exceptional strength and resistance to oxidation. Tensile strength of approximately 515 MPa, yield strength of 205 MPa, and elongation of approximately 40% are examples of mechanical properties. They are perfect for high-stress and thermal industrial settings because of their mechanical dependability, corrosion resistance, and heat resistance.

Stainless steel 310S fasteners are widely used in corrosive and high-temperature settings where durability and structural integrity are essential. Incinerators, heat exchangers, furnaces, and thermal processing machinery are examples of common applications. Additionally, petrochemical plants, power plants, marine structures, and industrial exhaust systems all make extensive use of these fasteners. They are appropriate for extreme thermal exposure and cyclic heating conditions due to their exceptional resistance to oxidation and scaling. They are ideal for welded assemblies because of their low carbon content, which also guarantees a lower chance of intergranular corrosion following welding. For long-lasting, performance-driven fastening solutions, 310S fasteners are the best option.
