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 →

Q: I’m using HCl in a pickling process and have used Hastelloy C276 bolts to protect my equipment but am still having corrosion issues. Any ideas? A: In pickling processes ferric chloride is created which is a strong oxidizer and most pickling process are at elevated temperatures – Hastelloy C276 … Continue reading →

Oilfields are subjected to a diversity of corrosive elements including carbonic acids, sour gas (H2S), and fracking/stimulant acids such as hydrochloric and hydrofluoric acid. Naphthenic acids and simple organic acids are also found in crude oil extraction. In conjunction to acids, these environments contain sand and other abrasive elements which … Continue reading →

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 →

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 →
