400 series stainless steel is widely used in the automobile exhaust pipe industry as steel for automobile exhaust pipes. In fact, in the eyes of many people, stainless steel is a tube problem in the entire automobile application.
However, they were wrong!
As shown in the figure above, in fact, “car exhaust pipe” is a common name for our car exhaust system. The entire car exhaust system includes exhaust manifolds, exhaust pipes, catalytic converters, exhaust temperature sensors, and automobiles. Muffler and tailpipe, etc.
Are you surprised to see this? How come there are so many parts? How to distinguish each part?
