316Ti Stainless Steel SS 316Ti vs 316L Diff

Published: November 12, 2025 | Updated: November 12, 2025By Gangsteel Engineering Team – 25+ Years in Stainless Steel Export Excellence

In the competitive landscape of stainless steels compliant with ASTM A240/A240M and ASME SA-240/SA-240M standards, the difference between SS 316Ti (titanium-stabilized austenitic) and 316L (low-carbon austenitic) lies in their stabilization methods, making SS 316Ti ideal for high-temperature welded applications and 316L for ambient corrosion resistance.

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

If you're debating SS 316Ti vs 316L under ASME SA-240/SA-240M for a heat exchanger or pressure vessel where sensitization risk and service temperature are factors, this guide provides a clear, data-driven comparison. We'll break down their differences in composition, properties, and applications, based on ASTM A240/A240M and ASME SA-240/SA-240M standards and our mill data.

From our production lines, we've seen the contrast: In a 2024 European power plant retrofit, our SS 316Ti tubes under ASTM A240 /A240M resisted IGC at 600°C, while 316L was used for ambient sections, as per client strain measurements. Compliant with ASME SA240/SA240M for pressure apps, both have density 8.00 g/cm³. Let's delve into SS 316Ti vs 316L, from composition to techniques, to equip you for successful selection.

Summary

SS 316Ti and 316L under ASTM A240/A240M and ASME SA-240/SA-240M are both austenitic grades for high-temp service, but SS 316Ti's titanium stabilization excels in heat; Gangsteel stocks with certs for custom guidance. SS 316Ti has tensile 515 MPa min, yield 205 MPa min, elongation 40% min, hardness 95 HRB max, and PREN 23-28 for IGC resistance at 425-815°C. Density 8.00 g/cm³, ideal for chemical reactors. Superior to 316L in welded high-temp; Gangsteel stocks 1-200mm with certs for custom needs.

Chemical Composition: The Key Diff

The chemical composition of SS 316Ti and 316L, as per ASTM A240/A240M and ASME SA-240/SA-240M, is optimized for stabilization, with SS 316Ti using titanium and 316L low carbon.

This composition under ASTM A240/A240M ensures SS 316Ti's heat advantage.

Gangsteel's SS 316Ti meets ASME SA-240/SA-240M for certified welding.

Physical Properties: Supporting Diff Selection

Physical properties of SS 316Ti, compliant with ASTM A240/A240M and ASME SA-240/SA-240M, aid diff selection.

These ensure diff efficiency.

Corrosion Resistance: Post-Weld Diff Highlight

SS 316Ti's corrosion resistance, per ASTM A240/A240M and ASME SA-240/SA-240M, is preserved with Ti.

• Uniform: <0.1 mm/year in acids; diff prevent depletion.
• IGC: Resistant with Ti; diff like Ti enhance.
• SCC: Good in chlorides; P number 8 aids qualification.
• Pitting: PREN 23-28; Mo in diff maintains.

Weldability and Fabrication: Diff in Practice

SS 316Ti is highly weldable, Ti aiding resistance in welds per ASTM A240/A240M. No preheat; good for diff-sensitive fab.

Gangsteel's SS 316Ti SA240 Type 316Ti maintains ratings post-weld.

Applications: Where Diff Matters

SS 316Ti's diff suits chemical reactors (welded with Ti), marine piping (outdoors).

In Gangsteel's supply to U.S. pharma, SS 316Ti welded without IGC.

FAQ: SS 316Ti vs 316L Difference Questions Answered

Q: What is the main difference between SS 316Ti and 316L stainless steel?

A: The main difference is stabilization: 316L uses ultra-low carbon (0.03% max) to prevent sensitization in ambient welds, while SS 316Ti adds titanium (0.70% max) to bind carbon for IGC resistance at 425-815°C.

Q: How does high-temperature performance differ between SS 316Ti and 316L?

A: SS 316Ti excels in high-temp IGC resistance due to Ti, retaining properties at 815°C continuous; 316L risks sensitization above 425°C, leading to corrosion in grain boundaries.

Q: Is SS 316Ti or 316L better for welding?

A: 316L is better for ambient welding with low C preventing sensitization; SS 316Ti is superior for high-temp service without PWHT.

Q: What is the cost difference between SS 316Ti and 316L?

A: SS 316Ti costs 10-15% more than 316L due to titanium, but offers better value in high-temp apps with 30% longer life.

Q: How do pitting and crevice corrosion compare for SS 316Ti and 316L?

A: Identical with Mo for pitting resistance (PREN 23-28); no significant difference in chlorides like seawater.

Q: Can I substitute 316L for SS 316Ti?

A: Yes for ambient conditions, but not for high-temp or welded apps where SS 316Ti's Ti prevents IGC; check service temp.

Q: What is the PREN of SS 316Ti vs 316L?

A: Both PREN 23-28; identical pitting resistance, but SS 316Ti's Ti adds no direct PREN benefit—Mo is the key.
