Q: I’m running a chemical cleaning process on stainless steel to remove the oxides and to enrich the chromium depleted areas again surface. It’s an acid pickling process, where mixtures of hydrofluoric acid (HF) and nitric acid (HNO3) are used. I’ve tried Hastelloy C276 bolting on my tanks because I thought … Continue reading →

Nickel alloys are a special class of metals containing high levels of nickel (often greater than 20%). They play a key role in industry for their unique combination of high strength, corrosion resistance to harsh acids (like hydrochloric and sulfuric) and high temperature stability. This two-part newsletter will help summarize the distinct benefits of the … Continue reading →

Q: I’m using hydrogen fluoride used in a manufacturing process to make refrigerants. I know it’s very corrosive and have tried both hastelloy and inconel fasteners, which I thought were super corrosion resistant. What am I doing wrong because the acid is still eating them? Should I try Tantalum? A: … Continue reading →

They rhyme, are both used in extreme environments, and are both nickel metal alloys, but Monel and Inconel are actually very different. But how? Let’s start with basic chemistry. Monel is a nickel-copper alloy and Inconel is a nickel-chromium alloy. So what does that mean for your extreme application? We … Continue reading →
