316Ti Stainless Steel and SA240 316 Material

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

In the rigorous domain of stainless steels compliant with ASTM A240/A240M and ASME SA-240/SA-240M standards, 316Ti and SA240 316 material represent two variants of the molybdenum-bearing austenitic family: 316Ti with titanium stabilization for high-temperature IGC resistance, and SA240 316 as the standard grade for general corrosion resistance in pressure vessels and piping.

As a premier producer and exporter based in China, Gangsteel has supplied thousands of tons of both 316Ti and SA240 316 material, meeting ASTM A240/A240M specs for plates and sheets, to industries like petrochemical, pharmaceutical, and marine.

If you're comparing 316Ti and SA240 316 material under ASME SA-240/SA-240M for welded structures or heat exchangers where sensitization, pitting, and cost are factors, this guide provides a data-driven overview. We'll explore their specs, properties, and differences, based on ASTM A240/A240M and ASME SA-240/SA-240M standards and our mill data.

From our production lines, we've seen the materials in action: In a 2024 U.S. chemical reactor project, our 316Ti plates under ASTM A240 /A240M outperformed SA240 316 in IGC tests at 600°C, extending service by 30% without PWHT, as per client A262 reports. Compliant with ASME SA240/SA240M for pressure apps, both have density 8.00 g/cm³. Let's delve into 316Ti and SA240 316 material, from composition to choice matrix, to guide your selection.

Summary

316Ti and SA240 316 material under ASTM A240/A240M and ASME SA-240/SA-240M are austenitic grades with PREN 23-28, but 316Ti's titanium (0.70% max) prevents IGC at 425-815°C, while SA240 316's higher carbon (0.08% max) risks sensitization in heat. Both share Cr 16-18%, Mo 2-3%, Ni 10-14%, tensile 515 MPa min, yield 205 MPa min, elongation 40% min. Density 8.00 g/cm³ identical. 316Ti costs 10-15% more but offers heat durability. Choose 316Ti for high-temp welds, SA240 316 for ambient. Gangsteel stocks both with certs.

Chemical Composition: The Stabilization Difference

316Ti's Ti (0.4-0.7%) forms TiC, protecting against sensitization in heat; SA240 316 risks Cr23C6.

Mechanical Properties: Comparable Strength

Both have similar mechanicals per ASTM A240/A240M and ASME SA-240/SA-240M.

316Ti's Ti prevents property loss from carbides at 425-815°C.

Physical Properties: Identical Foundations

Both share physical properties.

Similarity makes substitution easy.

Corrosion Resistance: 316Ti's High-Temp Edge

Both have excellent resistance (PREN 23-28), but 316Ti's Ti prevents IGC at sensitizing temps.

• Pitting/Crevice: Identical; CPT ~25°C.
• IGC: 316Ti superior with Ti; SA240 316 risks in heat.
• SCC: Both good; 316Ti better post-heat.
• Uniform: <0.1 mm/year in dilute acids; similar.
• High-Temp: 316Ti better for IGC; both for oxidation.

316Ti more reliable for welded high-heat.

Weldability and Fabrication: 316Ti's Advantage

Both weld well; SA240 316's higher C risks sensitization in heat, 316Ti's Ti eliminates it. Machinability ~60% for both.

Gangsteel's 316Ti offers heat weld edge.

Applications: Overlapping but Temp-Specific

• Common: Chemical piping (both durable).
• 316Ti Specific: High-temp reactors (IGC resistance).
• SA240 316 Specific: Ambient welded tanks (cost).

In Gangsteel's supply to U.S. pharma, 316Ti excelled in heated corrosives.

Cost Comparison: Similar with Availability Factor

In 2025, both ~$3,200-3,800/ton FOB China; 316Ti slightly higher for Ti.

Equivalents: Alternatives for Both

316Ti equivalents: EN 1.4571. SA240 316 equivalents: EN 1.4401. For A240 GR 316Ti, not interchangeable with SA240 316 in heat.

Sourcing from Gangsteel: Stock and Pricing

FAQ: Difference 316L and 316Ti Questions Answered

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

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

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

A: 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 316Ti or 316L better for welding?

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

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

A: 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 316L and 316Ti?

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

Q: Can I substitute 316L for 316Ti?

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

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

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