Products Description:310S Stainless Steel

1. What is 310S Stainless Steel?

310S (UNS S31008) is a low-carbon version of the 310 austenitic stainless steel . It is a high-temperature resistant alloy known for its excellent oxidation resistance and creep strength. The "S" stands for "low carbon," which significantly improves its performance during welding and high-temperature service.

This grade advantages: It combines the heat-resistant properties of a high-alloy steel with the workability and weldability ensured by its low-carbon chemistry (310S). It is the material of choice when projects demand reliability in cyclic high-temperature environments

2. Key Differences: 310 vs. 310S
While both grades are designed for high-temperature applications, the main difference lies in their carbon content:

Grade 310: Contains a higher carbon content (0.25% max), which provides higher strength at elevated temperatures but can lead to sensitization and embrittlement in certain environments .

Grade 310S: Has a lower carbon content (0.08% max). This reduces the risk of carbide precipitation at grain boundaries, offering better resistance to sensitization and maintaining ductility even after prolonged exposure to high heat.

3. Chemical Composition (Typical %)
The high Chromium and Nickel content gives this steel its "superior" status compared to standard grades like 304.

Chromium (Cr): 24.0 - 26.0

Nickel (Ni): 19.0 - 22.0

Carbon (C): 0.08 max

Manganese (Mn): 2.00 max

Silicon (Si): 1.50 max

Iron (Fe): Balance
