310S Stainless Steel vs 310 Stainless Steel: Differences & Selection Guide

1. What is the main difference in chemical composition between 310S and 310 stainless steel? Answer: The carbon content of 310S is ≤0.08%, while that of 310 is ≤0.25%, so 310S has better intergranular corrosion resistance.

2. Which one has better high-temperature creep resistance, 310 or 310S? Answer: 310S has better high-temperature creep resistance due to its lower carbon content, making it more suitable for long-term high-temperature applications.

3. In what scenarios should 310 stainless steel be selected instead of 310S? Answer: When the working environment has no strict requirements on intergranular corrosion resistance and cost is a concern, 310 stainless steel can be selected.

4. Are the welding performances of 310 and 310S stainless steel the same? Answer: Their welding performances are similar, but 310S requires stricter control of welding temperature and heat input to avoid intergranular corrosion.

5. Which one has a higher market price, 310 or 310S? Answer: 310S has a higher price because of its lower carbon content and better performance in some aspects.
