Aditya Stainless is a trusted manufacturer and supplier of Stainless Steel 309 Bolts, proudly based in Kolkata, India. We provide top-notch fastening solutions designed for high-temperature and corrosive environments. Crafted from heat-resistant alloy 309, these bolts are built to withstand oxidation and maintain mechanical strength, even in elevated temperatures. At Aditya Stainless, we ensure that every bolt meets international standards and comes in a variety of sizes, threads, and finishes. Perfect for applications in thermal processing, chemical plants, and heat exchangers, our commitment to precision, durability, and timely delivery has earned us the trust of industries both in India and beyond.
Stainless Steel 309 Bolts are made up of 22–24% chromium, 12–15% nickel, and low carbon (≤0.20%), which gives them exceptional oxidation resistance and high-temperature performance. These bolts boast a tensile strength of around 550 MPa, a yield strength of 205 MPa, and an elongation of 40%, making them both robust and flexible. They maintain structural integrity at temperatures reaching up to 980°C, making them perfect for thermal stress environments. The unique blend of their chemical composition and mechanical properties guarantees a long service life in both oxidizing and mildly reducing atmospheres.

Stainless Steel 309 Bolts are Fasteners with a high heat resistance that have good resistance to oxidation. They are perfect for severe environments and provide strength and reliability in mechanical and thermal conditions.
Custom Stainless Steel 309 Hex Bolt is a high heat resistant fastener in the shape of a square head with a specific shape, making it strong and reliable for severe heat and difficult areas.
The stainless steel 309 expansion anchor bolt is high temperature fastening and is made use of when fixing concrete or masonry construction. When tight clamped the same expands on the hole. Ensures perfect gripping.
The stainless steel 309 hex flange head bolt offers a hex-head feature with built-in flanges. It thus spreads the load with more weights, providing increased weight distribution and good heat resistance for overheating applications.
Stainless Steel 309 Full Threaded Bolts have full threads along their length, providing consistent clamping force and resistance to heat. They are perfect for high-temperature applications where durability and reliable performance are expected.
After manufacturing our quality control team performs extensive destructive and non-destructive tests on Stainless Steel 309 Bolts. By using advanced tools and techniques for the best possible performance and durability. Once the quality is checked these bolts are packed in a safe manner. With proper packaging material so that no damage occurs during transportation. We ensure timely and hassle-free delivery so that our customers receive their orders on time. All necessary documents are also provided to the client at the time of delivery so that there is transparency and reliability in our services.
Stainless Steel 309 Bolts find extensive use in high-temperature equipment like furnaces, kilns, heat exchangers, and boiler components, where heat and corrosion resistance are crucial. Industries such as petrochemical, refining, power generation, and thermal processing depend on these bolts for their reliability during thermal cycling. They are also utilized in flue gas systems, heat treatment trays, and oven linings, thanks to their outstanding scale resistance and mechanical performance. Moreover, their weldability and resistance to sulfur-bearing gases make them an excellent choice for challenging environments.
