Inconel 625 wire
Incoenl 625 Corrosion resistance
One of the mainly performance of 625 is inexorability in high temperature, even in very inclement conditions. If in the process of heating and cooling cycle, 625 can generate the dense layer of oxide film to get high spalling resistance. 625 have good carbonation resistance. With excellent inoxidability in the high temperature of sulfur atmosphere since it has high chromium and aluminum content.

Characteristic as below:
1. Excellent inoxidability in the high temperature.
2. Good resistance to carbonizing.
3. Good inoxidabilitiy in sulfur atmosphere
4.Good mechanical property in both room temperature and high temperature.
5.Good resistance to stress corrosion cracking, 601 have high creep rupture strength since it limits the carbon content and grain size, so recommend to use for above 500℃ environment.
Incoenl 625 Metallurgical structure:
601 is face-centered cubic lattice structure.
