Inconel 686 Seamless Pipe & Tube Supplier

As a high-quality nickel alloy supplier, we produce cost-effective Inconel 686 seamless pipe & tube.
Inconel 686 is a nickel-based superalloy that has unparalleled corrosion resistance through the synergistic effect of high content of chromium, molybdenum and tungsten. Inconel 686 seamless pipe & tube can withstand strong acid, strong alkali and mixed media corrosion, far exceeding conventional stainless steel (such as 316L). In extreme corrosive environments and high temperature and high pressure conditions, Inconel 686 seamless pipe & tube have become an ideal choice for chemical, marine engineering, aerospace and other fields due to their unique chemical composition and excellent mechanical properties.
Choosing Inconel 686 seamless pipe & tube means choosing long-term safety and low maintenance costs! We provide customized specifications and professional technical support to help you meet the most demanding engineering challenges.

Chemical Composition of Inconel 686

*Chemical Composition According to ASTM B622

Nickel, as a matrix element, provides a stable austenite structure to ensure creep resistance and toughness at high temperatures. Chromium forms a dense oxide film to resist erosion by oxidizing media (such as nitric acid and hot concentrated sulfuric acid). Molybdenum and tungsten double reinforced pitting and crevice corrosion resistance, especially in chloride ion (such as seawater, hydrochloric acid) environment.
