Product Features
1.Controlling iron and chromium at the lowest content, preventing the generation of β-phase NI4MO.
2. Excellent corrosion resistance to reducing environments.
3. Excellent resistance to medium concentration of sulphuric acid and many non-oxidising acids.
4. Very good resistance to chloride ion reduction stress corrosion cracking (SCC).
5. Excellent resistance to corrosion of various organic acids.
