Specifications
ASTM A312 TP309S (UNS S30908) is the low carbon version of the alloy. It is utilized for ease of fabrication. 309H (UNS S30909) is a high carbon modification developed for enhanced creep resistance. It most instances the grain size and carbon content of the plate can meet both the 309S and 309H requirements.

ASTM A312 TP309S Stainless Steel Tube Application
Key Distinction from TP309H:
TP309S vs. TP309H: While both offer excellent oxidation resistance, TP309S is chosen for its superior weldability and resistance to intergranular corrosion. TP309H is selected for its higher high-temperature strength and creep resistance but is more susceptible to sensitization in welded sections unless stabilized or solution annealed post-weld. TP309S is often used when post-weld heat treatment is not feasible.
