”CHOOSE PUXIN METAL AND LOOK FORWARD TO HEARING FROM YOU！“
310S stainless steel bar is a high-performance heat-resistant stainless steel material with excellent high temperature resistance, oxidation resistance and corrosion resistance. It can work stably in an environment up to 1200℃ and can operate continuously at 1150℃. Its high chromium and nickel content gives the material excellent resistance to high temperature oxidation, allowing it to maintain good mechanical properties and stability under extreme conditions. It is widely used in exhaust pipes, microwave ovens, high-temperature furnaces, cremation furnaces and other equipment with extremely high heat resistance requirements. It is also a key manufacturing material in the fields of aerospace, chemical industry, etc., and is suitable for the production of parts that are in high temperature environments for a long time.
As an outstanding representative of austenitic chromium-nickel stainless steel, 310S stainless steel bar exhibits unparalleled comprehensive performance under extreme working conditions with its high proportion of chromium (about 25%) and nickel (about 20%) core components. The material achieves solid solution strengthening effect through precisely controlled carbon addition, significantly improving tensile strength and high-temperature creep resistance, ensuring that it can maintain structural stability and mechanical integrity when subjected to high temperatures above 800°C for a long time. Its unique austenitic face-centered cubic crystal structure gives the material excellent ductility and fatigue resistance. At the same time, with the synergistic effect of trace alloying elements such as molybdenum and niobium, it further enhances its resistance to oxidative corrosion, acid-base medium erosion and sulfiding environment, and is especially suitable for application scenarios with frequent thermal cycles and drastic temperature fluctuations. In key areas such as electric heating furnace tubes, high-temperature reaction vessels, and heat treatment equipment, 310S stainless steel bars can not only effectively reduce the risk of downtime caused by material failure, but also greatly extend the life cycle of equipment with excellent long-term service performance, becoming the preferred structural material in high-temperature and high-pressure industrial environments.

APPLICATION
Nickel’s role in stainless steel becomes significant when combined with chromium. As an excellent corrosion-resistant material and a crucial alloying element in steel, nickel contributes to the formation of an austenitic structure. However, pure austenitic structure in low-carbon nickel steel requires a nickel content of at least 24%, and corrosion resistance in specific media improves significantly only at 27%. Therefore, nickel alone cannot create stainless steel, but when combined with chromium, it enhances the material’s properties, improving corrosion resistance and overall performance.
Due to the limited global nickel supply and its concentrated distribution, research has explored alternatives to nickel in stainless steel production. Manganese and nitrogen have been widely studied and applied as substitutes, particularly in countries where nickel resources are scarce. These elements have been used to replace nickel in stainless and heat-resistant steels, with industrial applications proving their effectiveness.
Manganese functions similarly to nickel in stabilizing austenite but does not directly form it. Instead, it lowers the critical quenching speed, increases austenite stability during cooling, and prevents its decomposition, allowing high-temperature austenite to persist at room temperature. However, manganese has a minimal effect on corrosion resistance. Even with variations in manganese content from 0% to 10.4%, there is no significant improvement in corrosion resistance in air or acidic environments. This is because manganese has little impact on raising the electrode potential of iron-based solid solutions and forms a weak protective oxide film. While manganese-alloyed austenitic steels, such as 40Mn18Cr4 and ZGMn13, exist, they are unsuitable as stainless steel.
In terms of stabilizing austenite, manganese is about half as effective as nickel, while nitrogen offers an even greater stabilizing effect. For instance, low-nickel stainless steels using manganese and nitrogen as substitutes have been successfully applied in industry, replacing traditional 18-8 chromium-nickel stainless steel in some cases.
