Chemical Properties
Hastelloy C-4 Rod resists sulfuric, hydrochloric, and nitric acids, plus alkalis. It performs in oxidizing and reducing environments but is not suited for prolonged use above 1000°C.
Things to Note (Limitations)
- Susceptible to damage under prolonged exposure to temperatures exceeding 1200°F (649°C).
- Reduced corrosion resistance in environments containing fluoride ions at high temperatures.
- Not suited for highly abrasive applications without proper surface treatment.
Corrosion Data
- Atmospheric (Rural): <0.01
- Sulfuric Acid (10%): 0.02 – 0.05
- Hydrochloric Acid (5%): 0.03 – 0.08
Welding and Manufacturing Tips
Hastelloy C-4 Rods are easily weldable using TIG, MIG, and submerged arc welding processes. Preheating is not required, and the material is compatible with both manual and automated fabrication techniques. Care should be taken to avoid rapid cooling, as it may lead to stress in the welded region.
