Inconel tubing brief introduction

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.

Inconel 600 tubing is known as alloy 600 tubing also, because Inconel 600 is the same as alloy 600. The chemical composition and mechanical properties are the same.

Inconel 718 tube

Inconel 718 tube is an important inconel tube made of nickel-chromium alloy. Our inconel pipe can be heat-treated to give high strength, good corrosion resistance, ease of formability and which can be welded with good resistance to strain age cracking. The inconel pipe can be used at temperatures up to 700ºC.

As one of the leading inconel tube suppliers and manufacturers in China, we also produce and sell inconel 718 tube to our customers home and abroad.
