Hastelloy B is a nickel-molybdenum based alloy that is highly resistant to corrosion in reducing environments such as hydrochloric acid and performs well under high temperature conditions.
Hastelloy B is a face-centered cubic lattice structure. By controlling the content of Fe and Cr at a small value, the brittleness of processing is reduced and the precipitation of N4Mo phase between 700 °C and 870°C is prevented. in the reduction of medium with very good corrosion resistance, such as a various temperature and concentration of hydrochloric acid. In the middle of the concentration of sulfuric acid solution (or contain a certain amount of chloride ions)
Hastelloy B Characteristic
- Control of iron and chromium content to a minimum to prevent the generation of β-phase Ni4Mo.
- Excellent corrosion resistance of restore environment.
- An excellent resist to concentration sulfuric acid medium and large number of non-oxidizing acid corrosion.
- A very good resistance of chloride reduction of stress corrosion cracking (SCC).
- Good corrosion resistance of various organic acids.
