Inconel 617 Wire
The Inconel 617 is a firm solution that is a hardened alloy comprises of Ni-Cr-Mo offers superior elevated temperature potential and resistance to oxidation. It offers supreme resistance to the various corrosion conditions and it is readily prepared as well as welded through traditional methods. The chemical composition of Inconel 617 is provided as following:

The large concentration of nickel and chromium provides high resistance to the reduction and oxidation factors. In the presence of aluminum and chromium the resistance to oxidation feature of Inconel 617 is increased. The firm solution reinforcing is provided by Cobalt and Molybdenum elements.
The blend of excellent potential and resistance to oxidation at the elevated temperatures more than 1800oF or 980oC that makes Inconel 617 a demanding alloy in the various purposes including ducts, transition liner, gas turbines and more. Due to its grand temperature level corrosion, it is implemented in the catalyst grid support in preparing acids such as nitric acid and reduction boats in the purification of molybdenum. The Inconel 617 provides excellent features for using in the power production houses that use nuclear energy and fossil fuels.
