WebApr 13, 2024 · The catalytic converter works by passing the exhaust gases through a honeycomb-like structure coated with the catalyst material. As the exhaust passes through this structure, it comes into contact with the catalyst which causes chemical reactions to take place that convert harmful pollutants into less harmful substances. WebSulfide stress cracking corrosion (SSC) is the cracking of metallic material under the combined effect of hydrogen sulfide and tensile stress. The important point is that compressive load cannot cause this type of corrosion. This type of corrosion is not classified as a general or uniform corrosion type; it can happen locally on special areas …
