Comparing 310 and 310S stainless steel pipes: 310 (≤0.25% C) offers superior high-temperature strength, suited for non-welded thermal environments (e.g., boilers); 310S (≤0.08% C) provides excellent weldability and cyclic heat stress resistance, with marginally higher cost but lower maintenance. A 1–2% density difference has minimal impact on most applications. Key uses: high-temperature structural components (310) vs. heat exchangers and welded systems (310S).
