It seems you cannot pick up a fastener publication without seeing something on Hydrogen Embrittlement (HE) – so even though you may be sick of hearing about it, before you decide that you really don’t need to read this article – read this: Hydrogen Embrittlement is not going away any time soon. Even if you do not have any exposure to this risk (fact is – if you are a fastener supplier you have exposure – period) it is in your best interest to understand it, and to help those of us who deal with it on a regular basis rid our industry of this insidious problem. In spite of all we have done to educate the industry, we still have regularly occurring HE cases that result in high-dollar costs to the supplier. In most cases, the supplier never saw it coming. I want to show you how to see it coming, how to avoid it, how to eliminate it from your risk matrix - and if you must be in the business of supplying HE susceptible fasteners, how to do it profitably and properly. Because this is The Distributor’s Link Magazine, these case studies will focus on fastener suppliers throughout the supply chain – manufacturers, importers, distributors, and retailers. However, HE has had its way with others in the industry. This includes platers, end users, the government and military, and even the occasional consultant (ask me how I know). When it comes to HE in fasteners there are three kinds of suppliers: TECHNICAL ARTICLE [1] Those who know what HE is and how to manage the risks [2] Those who can spell Hydrogen Embrittlement, maybe they know what it is – but they don’t know much beyond that [3] Those who are completely ignorant -maybe they have heard the term, but they know nothing about it. Over the past 20 or more years I have handled multiple HE cases for clients in each of these categories. This series of articles will examine cases that have affected each of these kinds of suppliers. The names of the suppliers, their customers, and sometime the description of the product may be withheld or changed for the sake of confidentiality. Ok – you got this far. If you are in the second or third category above, I encourage you to read the previous articles I have written for this magazine on HE. These articles will help inform you on the nature of HE, the whole issue of baking to relieve HE, and there is a very important article on HE failure investigation. If you are in the first category, you probably have already read these articles. Good. Go back and read them again. CASE NUMBER 1: The HE Problem That Did Not Actually Involve HE In this case, there was no HE, and there was no good reason to suspect HE, but because of the supplier’s failure to follow processing instructions regarding HE, a line was shut down, and assembled product was reworked and or scrapped.
