310S stainless steel and 310 stainless steel have notable differences in performance and applications. Here are the main distinctions:
310 Stainless Steel: Contains 24%-26% chromium and 19%-22% nickel, suitable for high-temperature applications.
310S Stainless Steel: Contains similar chromium and nickel proportions but has a lower carbon content (typically ≤0.08%), which enhances its welding properties and reduces the risk of embrittlement after welding.
310 Stainless Steel: Exhibits good high-temperature strength, making it suitable for extreme heat environments.
310S Stainless Steel: Due to its low carbon content, 310S has improved oxidation resistance and fire resistance at high temperatures, making it suitable for applications exposed to high-temperature gases.
310 Stainless Steel: Relatively poor welding performance, with potential embrittlement in the heat-affected zone after welding.
310S Stainless Steel: Superior welding performance; its low carbon content minimizes embrittlement after welding, making it suitable for applications requiring welding.
310 Stainless Steel: Widely used in high-temperature furnaces, heat treatment equipment, and other high-temperature environments.
310S Stainless Steel: More commonly used in environments with high-temperature gases and chemical media, such as chemical equipment and petroleum refining.
310 Stainless Steel: Exhibits good strength at high temperatures.
310S Stainless Steel: Maintains good toughness and ductility under high-temperature conditions due to its low carbon content.
Overall, 310S stainless steel outperforms 310 stainless steel in welding and high-temperature performance, making it more suitable for applications with stringent welding and high-temperature requirements. When selecting the appropriate material, it is essential to consider the specific application needs comprehensively.
