Hastelloy B2 (UNS N10665) is a nickel-molybdenum alloy associated with strong resistance in many reducing environments. Material selection must still consider contaminants, oxidizing species, temperature, concentration and fabrication history.
Key Selection Factors
| Factor | What the buyer should confirm |
|---|---|
| Process chemistry | Acid type, concentration, temperature, impurities, aeration and upset conditions |
| Product specification | ASTM B333 / ASME SB-333 or the project-specified equivalent |
| Condition | Solution-treated condition and any project-specific heat-treatment requirement |
| Fabrication | Qualified welding procedures, controlled heat input and suitable filler selection |
Important Service Limitation
B2 is not a universal corrosion-resistant alloy. Strongly oxidizing media and oxidizing contaminants can materially change performance. Selection should be based on actual process data and, when necessary, corrosion testing or advice from the responsible materials engineer.
