In the precision domain of stainless steels compliant with ASTM A240/A240M and ASME SA240/SA240M standards, choosing between 316Ti (titanium-stabilized) and 316L (low-carbon) is a critical decision for applications where weld integrity, high-temperature performance, and corrosion resistance are paramount.
As a premier producer and exporter based in China, Gangsteel has supplied thousands of tons of both 316Ti and 316L stainless steel, meeting ASTM A240/A240M specs for plates and sheets, to industries like petrochemical, pharmaceutical, and marine.
If you're deciding 316Ti or 316L under ASME SA240/SA240M for a welded pressure vessel, heat exchanger, or piping system where sensitization risk and service temperature are key factors, this guide provides a clear, data-driven comparison to help you make the right choice. Based on ASTM A240/A240M and ASME SA240/SA240M standards and our mill data.
From our production lines, we've seen the choice in action: In a 2024 U.S. chemical reactor project, 316Ti under ASTM A240 /A240M was selected over 316L to eliminate post-weld heat treatment (PWHT) at 600°C, saving 20% in fabrication cost while ensuring zero IGC, as confirmed by ASTM A262 Practice E testing. Compliant with ASME SA240/SA240M for pressure apps, both have density 8.00 g/cm³. Let's break down 316Ti or 316L choice, from composition to decision matrix, to guide your selection.

Q: Should I choose 316Ti or 316L for welding?A: Both weld without PWHT. Choose 316L for <425°C; 316Ti if weld will see 425–815°C.
Q: Is 316Ti worth the extra cost over 316L?A: Yes — if operating or cycling above 425°C. Saves on PWHT, repairs, and downtime.
Q: Can I use 316L instead of 316Ti?A: Only if no heat exposure >425°C post-weld. Otherwise, risk IGC.
Q: What is the main difference in 316Ti or 316L choice?A: 316L = low carbon for ambient. 316Ti = titanium for heat.
Q: Which has better corrosion resistance — 316Ti or 316L?A: Equal in pitting/uniform. 316Ti wins in IGC after heat.
Q: Where can I buy 316Ti or 316L with fast delivery?A: Gangsteel — stock in LA warehouse, 7–15 day delivery, certs included.
