C4 seamless pipe is better than many other corrosion-resistant alloys. It can resist chloride-induced SCC, doesn’t crack quickly, can withstand extreme temperatures (up to 1040°C), and provides better strength due to the higher amount of molybdenum in it.
ASTM B622 Alloy C4 Seamless Pipe Manufacturer
We, Zhejiang Xintongda Special Steel Manufacturing (XTD), are a China-based manufacturer and global supplier of Alloy C4 seamless pipes. C4 pipe is a high-performing tubular product made from an alloy of nickel (balance), chromium (14-18%), and molybdenum (14-17%). This UNS N06455 pipe has a high amount of nickel, a balanced amount of chromium and molybdenum (approximately 15%), and a very low amount of carbon (less than or equal to 0.015%). We manufacture our Alloy C4 pipes in adherence to the ASTM B622 standard. The properties of the C4 pipe make it highly resistant to grain boundary precipitation in the heat-affected zones (HAZ) and chemicals. Alloy C4 pipe is an ideal choice for chemical processing, nuclear, and pollution control applications.
We are a leading manufacturer of this seamless pipe, and our supply capacity is 25,000 tons. With more than 4 decades of experience, we can deliver the in-stock products within a week and production orders in 15-60 days. Since we are ISO certified, many industries rely on us as an Alloy C4 pipe supplier.

Manufacturing Process of Alloy C4 Pipe
We at XTD manufacture the Alloy C4 alloy pipe by taking a solid billet of nickel-chromium-molybdenum, and then heating those billets so they can be pierced and elongated into a hollow shell. Then, we cold roll or cold draw this shell according to the required thickness and diameter. After it gets its shape, the pipe goes through a heat treatment where its corrosion resistance is strengthened. Our last step is to straighten, clean the surface, and test to ensure it meets the quality standards. To check out the whole manufacturing process, visit this page.
What are the Key Features of Seamless C4 Alloy Pipe?
There are 3 main features of the Seamless Alloy C4 Pipes: high-temperature stability, corrosion resistance, and weldability.
- High-Temperature Stability: It has the power to withstand extreme temperatures ranging from 649-1038°C (1200-1900°F).
- Corrosion Resistance: It doesn't corrode easily when it comes into contact with contaminated mineral acids, organic acids, chlorine, seawater, brine, and other harsh chemicals.
- Weldability: This alloy is easily welded using TIG, MIG, or stick welding methods without risk of cracking.
These features make it highly favourable for industrial applications with highly corrosive and extremely high-temperature environments.

What Industries Commonly Use Alloy C4 Pipe?
C4 pipe is extensively used in many industries due to its exceptional capabilities. Here are 5 prominent applications:
Chemical Processing
Generally used to transfer aggressive acids and halides. It can also be seen in heat exchangers, evaporators, and reaction vessels.
Thermal Processing
Since C4 doesn’t lose its strength in elevated temperatures, it is used in many thermal processing equipment, like pickling tank equipment and titanium dioxide production.
Waste Treatment, Paper and Pulp Production
It is used for piping and process lines that carry acidic or chloride-containing pulps and wastes.
Pollution Control
Scrubbers, dampers, flue gas desulfurization systems, and stack liners use C4 seamless pipe.
Nuclear & Aerospace
This pipe is mainly used for nuclear coolant systems and high-temperature aircraft exhaust or fuel systems.
