W.Nr. 2.4668 Inconel 718 Welded Pipe Tempering Reactor Vessels Heat Exchangers Pipes
1. As a leading Chinese Inconel alloy supplier, DINGSCO manufactures and produces different sizes of Inconel Alloy 718 pipes.
2. INCONEL® alloy 718 (UNS N07718 / W.Nr. 2.4668) is a high-strength, corrosion-resistant nickel chromium material used at -423° to 1300°F. The age-hardenable alloy can be readily fabricated, even into complex parts. Its welding characteristics, especially its resistance to postweld cracking, are outstanding.
3. Inconel 718 welded pipe & tube is a kind of Inconel 718 pipe or tube formed by bending and welding the Inconel 718 strip or Inconel 718 plate, so the quality of raw materials is very important and decisive. In DINGSCO, we choose the raw materials from big factory and use the most advanced splitting and welding technology to manufacture every Inconel 718 welded pipe & tube. If you need solution annealed Inconel 718 welded pipe or tube to meet the higher demand, we can also anneal the pipe or tube with our online solid solution equipment.
