ASTM A276 316Ti / UNS S31635 / 1.4571 Stainless Steel Round Bar

With Corrosion Resistance and High-Temperature Resistance**

---

Product Description

The ASTM A276 316Ti Stainless Steel Round Bar, designated as UNS S31635 and EN 1.4571, is a titanium-stabilized austenitic stainless steel designed for exceptional performance in corrosive and high-temperature environments. Its chemical balance—particularly the addition of titanium—inhibits carbide formation, ensuring long-term resistance to intergranular corrosion even after prolonged heating cycles.

Our 316Ti round bars are produced through hot rolling, forging, or precision machining, supplied in diameters from 10 mm to 350 mm, and available in custom-cut lengths to suit diverse industrial requirements. With outstanding resistance to chlorides, acids, and elevated temperatures, this grade is widely used in chemical plants, marine systems, food processing lines, energy equipment, and high-temperature process zones.

Chemical Composition

316Ti contains chromium, nickel, and molybdenum in controlled proportions, strengthened by titanium to improve stability at elevated temperatures.

Key Characteristics & Advantages

316Ti stainless steel offers enhanced performance over standard 316/316L grades, particularly in harsh or high-temperature environments.

1. Superior Corrosion Resistance

• Excellent resistance to chloride-induced pitting and crevice corrosion

• Enhanced resistance in acidic environments (sulfuric, acetic, phosphoric acids)

• Ideal for coastal, marine, and chemically contaminated environments

2. Outstanding High-Temperature Stability

Titanium stabilization prevents chromium carbide formation, making the alloy suitable for:

• Continuous service temperatures up to 600°C

• Long exposure in heat exchangers and superheated piping

• Applications requiring strong resistance to sensitization

3. Excellent Mechanical Strength

• Maintains structural integrity under stress

• Superior creep and stress-rupture resistance compared to 316/316L

• Ideal for pressure-retaining components

4. Reliable Fabrication and Welding Performance

• Good weldability with TIG, MIG, or SMAW processes

• No need for post-weld annealing in most cases

• Good machinability for precision-engineered parts

5. Long Service Life

Its combined corrosion and heat resistance ensures long operational life under demanding service conditions.

FAQ – Frequently Asked Questions

1. What makes 316Ti different from 316 and 316L?

316Ti contains titanium, which stabilizes the alloy at high temperatures and protects against intergranular corrosion.
316L offers low carbon content but cannot match the high-temperature stability of 316Ti.

2. Are 316Ti round bars suitable for welding?

Yes. Titanium prevents carbide precipitation, allowing welded components to retain corrosion resistance without requiring heavy post-weld heat treatment.

3. What surface finishes are available?

We provide hot rolled, peeled, polished, and centerless-ground bars depending on dimensional and aesthetic requirements.

4. Can you provide customized processing services?

Yes. We offer:

• Precision cutting

• CNC machining

• Threading and turning

• Polishing and grinding

• UT and third-party inspection

5. What is the typical lead time for orders?

• In-stock items: 3–7 days

• Customized machining: 10–20 days

• Large volume production: 20–30 days

6. Do you provide samples?

Sample pieces can be provided for technical evaluation, depending on size availability.

7. Where are 316Ti round bars commonly used?

In chemical plants, refineries, marine engineering, food production, pharmaceutical systems, pressure vessels, and heat exchangers.

8. Can you export globally?

Yes. We serve customers across Europe, America, the Middle East, Southeast Asia, and other regions with stable supply chains and professional export documentation.
