Stainless Steel 309 and 310 are high-alloy austenitic stainless steel bars known for their excellent high-temperature performance and corrosion resistance.

Stainless Steel 309 bars are primarily composed of iron, chromium, and nickel, with additional elements such as manganese, silicon, and carbon. This alloy offers exceptional resistance to oxidation and high-temperature exposure, making it well-suited for applications in furnace parts, heat exchangers, and other high-temperature environments. The chemical composition of Stainless Steel 309 provides it with excellent strength and toughness, allowing it to withstand thermal cycling and mechanical stresses at elevated temperatures.

On the other hand, Stainless Steel 310 bars are also composed of iron, chromium, and nickel but contain a higher concentration of chromium and a small amount of silicon. The increased chromium content enhances its resistance to oxidation and corrosion, even in environments with high sulfur or carbon content. This makes Stainless Steel 310 ideal for use in furnace linings, combustion chambers, and radiant tubes in industrial settings.

Both Stainless Steel 309 and 310 bars exhibit exceptional corrosion resistance, particularly in high-temperature and mildly corrosive environments. They are not prone to intergranular corrosion, ensuring their reliability in various applications, even after prolonged exposure to corrosive elements.
