Nickel Alloy Inconel 601 Pipe And Fittings has the following characteristics:
1. Excellent resistance to oxidation at high temperatures
2. Very good resistance to carbonization
3. can be a good antioxidant sulfur atmosphere
4. Good mechanical properties at room temperature and at high temperatures
5. Good resistance to stress corrosion cracking performance due to control of carbon content and grain size, 601 has a high creep rupture strength, so 500 ℃ above the area recommended 601.
Nickel Alloy Inconel 601 Pipe And Fittings metallographic structure: 601 is a face-centered cubic lattice structure.
Alloy 601 Pipe And Fittings corrosion resistance:
Nickel Alloy Inconel 601 Pipes And Fittings is an important performance is the temperature up to 1180 ℃ with antioxidant. Even in very harsh conditions, such as heating and cooling cycles, 601 can produce a layer of dense oxide film and get a high anti-peeling. 601 has good resistance to carbonization. Due to the higher chromium, aluminum content, 601 in the high temperature sulfur atmosphere has a good antioxidant.
