HE- Hydrogen Embrittlement/ HSC- Hydrogen Stress Cracking/ Biofilm/ H2S Sour Gas / Internal Hydrogen in Processing
It has been eight years since I jumped into HE/HSC full force. Identifying internal hydrogen factors, calling out process failures, running fracture testing on known causes and some less know causes. Most of the time the failure is right in front of us. In looking at most all types of HSC failures I have put together two process which counter many variables that could go wrong no matter who is processing the parts. In other words I removed as much of the variables within the applications, but still was able to produce a product. Different process would be applied depending on if it was wire, threaded or machined. I take into account the ability to attack grain structure , by making the surface amorphous. I then diffuse metallic and some times semi-metallic vapor into the vacancies of the metal substrate. This is not done only with thermal , oh no. It is done with a recipe of different processes.
