Chemical Properties

Hastelloy B3 Bar offers exceptional resistance to acids like hydrochloric, sulfuric, and phosphoric. It performs well in reducing environments but is not suitable for oxidizing conditions.

Things to Note (Limitations)

The Hastelloy G30 Bar has constraints:

Reducing Environments: Less resistant than B2 in strong reducing acids like hydrochloric.
High Temperatures: Strength may decrease above 900°C.
Cost: Higher than stainless steel due to alloy complexity.

Our China distributor can recommend alternatives if needed.

Corrosion Data

Atmospheric: Excellent resistance in all conditions.
Oxidizing Acids: Superior against phosphoric and sulfuric acids.
Mild Chemicals: Good resistance to dilute acids and solvents.

Welding and Manufacturing Tips

Use TIG or MIG welding for Hastelloy B3 Bar. It supports forming and machining, but low cutting speeds are advised due to its strength. Anneal after fabrication for optimal results.
