309S/310S Stainless Steel Bar/Rod
High-Temperature Strength | Oxidation Resistance | Thermal Stability
Specifically designed for furnace components, kilns, and thermal processing equipment.
Select the profile optimized for your high-heat application:
Primary Use: Furnace conveyor belts, heating elements, and boiler supports.
Key Edge: Precision straightening prevents thermal warping during high-speed rotation.
Primary Use: High-temp bolts, kiln fittings, and thermal assembly connectors.
Key Edge: Stable dimensions ensure fasteners remain removable after long-term heat exposure.
Primary Use: Furnace muffles, firebox liners, and heat exchanger baffles.
Key Edge: Excellent weldability for constructing rigid thermal structures.
Your Concern: Bars cracking under repeated heating and cooling cycles.
Our Solution: Our 310S bars feature high Nickel (20%) and Chromium (25%) content, providing a stable austenitic structure that resists "sigma phase" embrittlement and thermal fatigue.
Your Concern: Rapid reduction in material thickness due to surface scaling in high heat.
Our Solution: We provide materials with a high-purity protective oxide layer. Our 309S/310S grades maintain their structural integrity and surface finish even in continuous-service furnace environments.
Your Concern: Components stretching or deforming over time under load and heat.
Our Solution: We offer precision-annealed bars with optimized grain structures to ensure maximum creep-rupture strength for long-term industrial reliability.
Global Footprint: Proven track record in supplying specialized heat-resistant alloys for global heavy industries, including thermal power plants, cement kilns, and chemical refineries.
Specialized Inventory: Significant stock of 309S and 310S grades available in various diameters, leveraging the Wuxi/Tisco high-alloy supply hub.
Secure Global Transit: Each shipment is packed in reinforced seaworthy crates with protective coatings to ensure the material arrives in factory-fresh condition, ready for the furnace.
