Hastelloy alloys have long been the gold standard of corrosion resistant bolts; only out performed by metals like Zirconium and Tantalum. This family of high performance nickel alloys can handle strong acids like hydrochloric, sulfuric, acetic, formic and phosphoric acids, yet each grade actually exhibits its own strengths in dealing with specific acids and niche environments. … Continue reading →

Q: I was planning on using Hastelloy C276 in hot sulfuric acid. It would be approximately 50% concentration around 100F +/- 10 degrees. Will this be okay? I’m just concerned because I read that it cannot handle strong oxidizing environments and I’ll be using it in an application where its … Continue reading →

Q: I’m using zirconium fasteners in a sulfuric acid process but they are showing corrosion. I’m not sure why as I’m well below boiling and only using 40% concentration. There may be some downstream contaminants, but not much. Any ideas? A: It is most likely the contaminants that are causing … Continue reading →

Q: I have a waste water purifying situation where I’m using chlorine to treat the water. In addition to the acidic solution produced the fastener will also experience high loads, so I’m also concerned with stress corrosion cracking. Currently Super Duplex 2507 is not doing the job. Any recommendations on … Continue reading →
