C276 tubing has excellent corrosion resistance in a broad range of extreme environments. Due to the high molybdenum content, C276 alloy especially has good performance on resistance to pitting and crevice corrosion. The low carbon content minimizes carbide precipitation during welding to maintain corrosion resistance in as-welded structures.
Monel tubing usually refers to Monel 400 tubing, because Monel 400 is the most famous and popular nickel alloy of the Monel series. Younglee manufacturers and supplies high quality Monel 400 tubing / Monel 400 pipe with sizes and requirements upon customer’s requests.
Monel 400 tubing is widely used in many industrial areas, especially in the industries of marine and chemical processing.
As one of the first class quality monel tube suppliers & manufacturers, Younglee produces and supplies various different sizes of monel tubing /monel 400 pipe.
Size range: O.D 6 mm – O.D 50 mm
Here below are some popular dimensions of Monel 400 pipe:
Other dimensions are available upon customer’s request.

Monel 400 pipe / Monel 400 tubing is broadly used in industries of Chemical processing, Oil and gas, Nuclear and Power, for the advantages of high strength and toughness over a wide temperature range and excellent resistance to many corrosive environments.
And here below are some typical applications of monel 400 tubing:
Inconel tubing of Younglee is seamless tube made of inconel alloys, which are nonmagnetic, high corrosion resistant, heat resistant and oxidation resistant, nickel-based alloys.
Inconel tube has high strength and toughness in the extreme high temperature applications. And Inconel alloys have excellent fatigue strength and stress-corrosion cracking resistance to chloride ions, so nickel alloy inconel tubing is suitable for conveying various solutions containing Cl and caustic soda with concentration <70% and many other fluids.
As one of the first class inconel tubing suppliers and manufacturers in China, Younglee manufactures inconel pipes with size range O.D 5 mm – 50.8 mm in most popular inconel alloys, including inconel 600, inconel 625 and inconel 718.
