316Ti Stainless Steel AISI 316Ti Equivalent

Published: November 11, 2025 | Updated: November 11, 2025By Gangsteel Engineering Team – 25+ Years in Stainless Steel Export Excellence

In the global stainless steel landscape compliant with ASTM A240/A240M and ASME SA240/SA240M standards, AISI 316Ti stainless steel emerges as a titanium-stabilized austenitic grade whose equivalents enable seamless material substitution across international standards for high-temperature and corrosive applications.

As a premier producer and exporter based in China, Gangsteel has supplied thousands of tons of AISI 316Ti stainless steel, meeting ASTM A240/A240M specs for plates and sheets, to industries like petrochemical, pharmaceutical, and marine.

If you're verifying equivalents for AISI 316Ti under ASME SA240/SA240M for a welded reactor or marine piping where cross-standard compliance is key, understanding its alternatives like EN 1.4571 or JIS SUS316Ti is vital. This article provides a comprehensive equivalent list for AISI 316Ti, property comparisons, and practical insights, based on ASTM A240/A240M and ASME SA240/SA240M standards and our mill data.

From our production lines, we've facilitated equivalent swaps: In a 2024 UK chemical project, our AISI 316Ti plates under ASTM A240 /A240M matched EN 1.4571 materials for traceability, allowing direct substitution without re-certification, saving 15% on compliance as per client reports. Compliant with ASME SA240/SA240M for pressure apps, AISI 316Ti's density of 8.00 g/cm³ supports equivalent designs. Let's delve into the equivalents, from composition to applications, to guide your sourcing.

Summary

AISI 316Ti stainless steel (UNS S31635) has equivalents including EN/DIN 1.4571 (X6CrNiMoTi17-12-2), JIS SUS316Ti, BS 320S31, AFNOR Z6CNDT17-12, SS 2350, GOST 08Ch17N13M2T, and GB/T 20878 – 06Cr17Ni12Mo2Ti, all sharing titanium stabilization for IGC resistance, tensile strength 515 MPa min, yield 205 MPa min, and elongation 40% min. Density 8.00 g/cm³, PREN 23-28 across equivalents. Minor range differences (e.g., Ni) don't affect equivalence for most apps under ASTM A240/A240M and EN 10088. Ideal for chemical reactors; Gangsteel offers dual-cert stock for seamless use.

Property Comparison: Why Equivalents Work

Equivalents like 1.4571 have nearly identical properties to AISI 316Ti, with minor range variations.

Chemical Composition (% by Weight)

Mechanical Properties (Annealed Min)

Corrosion: Both PREN 23-28; equivalents for IGC/high-temp.

Physical Properties: Identical for Equivalents

All equivalents share physical properties.

This equivalence supports direct design swaps.

Corrosion Resistance: Equivalent Protection

All have PREN 23-28 for similar corrosion, with Ti preventing IGC.

• Pitting: CPT ~25°C.
• IGC: Resistant with Ti.
• SCC: Equivalent in chlorides.
• Uniform: <0.1 mm/year in acids.

Weldability and Fabrication: Equivalent Ease

All weld well; Ti eliminates annealing. Machinability ~60% for all.

Gangsteel's AISI 316Ti SA240 Type 316Ti matches equivalents.

Applications: Shared for Equivalents

All used in chemical reactors, marine fittings, power boilers—equivalence allows swaps.

In Gangsteel's supply to U.S. pharma, AISI 316Ti matched equivalents without issue.
