1. What Is Inconel 600?

Inconel 600, also known as UNS N06600, is a nickel-chromium-iron alloy developed for applications requiring resistance to corrosion and high temperatures. It maintains structural integrity and mechanical strength in both oxidizing and reducing conditions, making it one of the most versatile alloys for seamless tube production.

2. Chemical Composition of Inconel 600

The high nickel content ensures superior resistance to corrosion and stress-related cracking in a wide range of environments.

3. Key Properties of Inconel 600 Seamless Tubes

a) High Temperature Resistance

Inconel 600 retains its mechanical properties at temperatures up to 1093°C (2000°F), making it suitable for heat exchangers, furnace components, and thermal processing equipment.

b) Superior Corrosion Resistance

It resists a wide range of corrosive media including organic and inorganic compounds, caustic alkalis, and chloride-ion stress cracking.

c) Excellent Mechanical Strength

High tensile strength, good elongation, and creep resistance enable Inconel 600 to function in environments with significant thermal and mechanical stress.

d) Oxidation and Scaling Resistance

Its chromium content provides resistance to oxidation even in elevated temperature atmospheres such as combustion systems and nuclear reactors.

e) Non-Magnetic and Stable Structure

Inconel 600 is non-magnetic and remains stable under thermal cycling conditions, which enhances its reliability in sensitive engineering systems.

4. Standards and Specifications

Inconel 600 seamless tubes comply with international standards including:

• ASTM B167 – Seamless tubes

• ASME SB167

• DIN 17751

• NACE MR0175 for sour service

• ISO 6207

sasaalloy supplies Inconel 600 tubes with full material traceability and quality documentation in accordance with these standards.

5. Dimensions and Tolerances

At sasaalloy, we provide a wide range of Inconel 600 seamless tubes in the following specifications:

• Outer Diameter: 6mm – 114mm

• Wall Thickness: 0.5mm – 12mm

• Length: Up to 12 meters or as per custom requirement

• Tolerances: According to ASTM B167 or client-specific needs

Custom machining, cut-to-length, and beveled-end options are available upon request.

6. Typical Mechanical Properties

Note: Mechanical properties can vary depending on tube size, manufacturing process, and heat treatment.

7. Applications of Inconel 600 Seamless Tubes

a) Chemical Processing

• Tubing for reactors and heat exchangers handling caustic or acidic solutions

• Handling chlorinated hydrocarbons and nitric acid mixtures

b) Power Generation

• Steam generator tubes

• High-pressure boiler piping

• Tubes in nuclear reactors and waste heat boilers

c) Aerospace and Aviation

• Fuel lines and hydraulic tubing

• Exhaust ducting

• Engine components exposed to heat and oxidation

d) Marine Engineering

• Tubes used in saltwater environments

• Seawater cooling systems

e) Heat Treatment Industries

• Furnace tubing

• Carburizing and nitriding atmosphere applications

In all these areas, sasaalloy provides Inconel 600 seamless tubes with precise dimensions, consistent quality, and excellent heat and corrosion performance.

8. Fabrication and Machinability

Inconel 600 is easily fabricated by conventional techniques:

• Welding: TIG and MIG welding is effective with proper filler metal selection (Inconel 82 or 182 recommended)

• Forming: Hot or cold forming is possible. Pre-heating is often recommended for heavy sections

• Machining: Use low-speed, high-feed carbide tools due to the work-hardening nature of the alloy

sasaalloy offers tubes with mill finish, pickled and passivated, or polished surfaces depending on customer needs.

9. Benefits of Seamless Tube Construction

Compared to welded tubes, seamless tubes provide:

• Higher pressure resistance

• No weak weld seams

• Better surface finish

• Improved uniformity

This makes seamless Inconel 600 tubes the top choice for critical pressure systems and high-temperature performance.

10. Quality Assurance and Documentation

All Inconel 600 tubes from sasaalloy are delivered with:

• Material Test Certificate (MTC) as per EN 10204 3.1 / 3.2

• Third-party inspection reports (on request)

• Hydrostatic and NDT reports

• Dimensional, visual, and PMI test reports

We ensure every shipment meets your industry and project requirements with full traceability and technical support.

Conclusion

Inconel 600 seamless tubes offer unmatched performance in environments where high heat, corrosive chemicals, and mechanical stress are the norm. Their reliable composition and robust mechanical properties make them an ideal solution in energy, aerospace, chemical, and marine industries.
