In the standardized world of stainless steels compliant with ASTM A240/A240M and ASME SA240/SA240M, 316Ti steel is a titanium-stabilized austenitic stainless steel — an enhanced version of the popular 316 steel (18% chromium, 10% nickel, 2–3% molybdenum) specifically engineered to prevent intergranular corrosion (IGC) during welding and high-temperature service by adding titanium to bind carbon and protect chromium from depletion.
As a premier producer and exporter based in China, Gangsteel has supplied thousands of tons of 316Ti steel, meeting ASTM A240/A240M specs for plates and sheets, to industries like petrochemical, pharmaceutical, and marine.
If you're asking what is 316Ti steel under ASME SA240/SA240M for selecting components in welded pressure vessels, heat exchangers, or exhaust systems where long-term durability in corrosive and elevated temperatures is required, this guide clearly explains 316Ti steel — its composition, purpose, benefits, and applications — based on ASTM A240/A240M – 316Ti (UNS S31635) and ASME SA240/SA240M – 316Ti standards and our mill data.
From our production lines, 316Ti steel in action: In a 2024 U.S. power plant retrofit, our 316Ti steel plates under ASTM A240 /A240M — titanium-stabilized to resist IGC — operated at 600°C without degradation for 12 months, outperforming standard 316 steel by eliminating sensitization, as per client inspection reports. Compliant with ASME SA240/SA240M for pressure apps, 316Ti steel's density of 8.00 g/cm³ supports robust, lightweight designs. Let's explain what 316Ti steel is, from chemistry to real-world use, to help you choose wisely.
What is 316Ti steel?It is a titanium-stabilized austenitic stainless steel (UNS S31635) based on 316 steel alloy (18Cr–10Ni–2Mo), with 0.70% max titanium added to prevent intergranular corrosion (IGC) at 425–815°C by forming TiC instead of Cr-carbides. Under ASTM A240/A240M and ASME SA240/SA240M, it offers tensile 515 MPa min, yield 205 MPa min, elongation 40% min, hardness 95 HRB max, and PREN 23–28. Density 8.00 g/cm³. Equivalent to EN 1.4571. Superior to 316L steel in welded high-temp service; ideal for reactors and exhausts. Gangsteel stocks 1–200mm with certs.
The chemical composition of 316Ti steel, as per ASTM A240/A240M – 316Ti (UNS S31635) and ASME SA240/SA240M – 316Ti, is the foundation of what 316Ti steel is — a stabilized 316.

316Ti steel explained: 316 steel + Ti stabilization — Ti forms TiC/TiN, leaving Cr free for passivation.
Gangsteel's 316Ti steel ensures Ti ratio >5x(C+N) for full stabilization.
For uns stainless steel plates, 316Ti steel composition verified.
316Ti steel's mechanical properties, per ASTM A240/A240M – 316Ti and ASME SA240/SA240M – 316Ti, show what 316Ti steel is — strong and formable.

Q: What is 316Ti steel?
A: 316Ti steel is 316 stainless steel with titanium added (0.70% max) to prevent intergranular corrosion during welding and high-temperature service (425–815°C).
Q: Why is titanium added to 316Ti steel?
A: Titanium binds carbon to form TiC, preventing chromium carbides that cause IGC — allowing safe welding without post-weld heat treatment.
Q: Is 316Ti steel magnetic?
A: No — fully austenitic, non-magnetic in annealed condition.
Q: Can 316Ti steel be used for food contact?
A: Yes — FDA-compliant, non-toxic, used in pharmaceutical and food equipment.
Q: What is the difference between 316Ti steel and 316L steel?
A: 316L steel has lower carbon (0.03%) for ambient welding; 316Ti steel has titanium for high-temp IGC resistance.
Q: What does the "Ti" in 316Ti steel stand for?
A: Ti = Titanium — the stabilizing element.
Q: Where to buy 316Ti steel?
A: Gangsteel — mill-direct, $3,200–3,800/ton FOB, 1–200mm thick. Email: admin@gangsteel.com
