Stainless Steel 446 Fasteners consist mainly of chromium (23–27%), iron, and tiny amounts of manganese, silicon, carbon, and nickel. This ferritic stainless steel with high chromium provides superb resistance to corrosion and oxidation at high temperatures. Mechanically, SS 446 bolts have a tensile strength of approximately 485 MPa and a yield strength of about 275 MPa, with fair elongation. Their superb scaling resistance up to 1100°C makes them well suited for thermal services. These bolts also provide fair formability and stability, which guarantees long-term performance in harsh conditions.

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.
Stainless Steel 446 Fasteners find extensive application in high-temperature and corrosive environments because of their high heat and resistance to oxidation. They are used best in furnace components, heat exchangers, boiler fittings, and kilns. In the petrochemical industry, fasteners are used under thermal cycling conditions. Power generation plants and chemical processing industries also use SS 446 fasteners because of their reliability and durability. Further, they are also ideal for exhaust systems, refractory anchoring systems, and thermal oxidizers. Their strength and integrity properties at extreme temperatures make them among the best options for industrial and structural purposes in all industries.
We are committed to ensuring the highest quality of our materials and achieving complete client satisfaction. To uphold these standards, all our products undergo rigorous quality testing. Our comprehensive testing procedures include hardness tests, chemical analysis via spectroanalysis, positive material identification (PMI), flattening tests, and micro and macro examinations. Additionally, we conduct pitting resistance tests, flaring tests, and intergranular corrosion (IGC) tests to ensure the reliability and performance of our products.
