.... Carbon steels used at high temperature for pressure vessels and piping typically have a microstructure of ferrite and pearlite, and with extended exposure to temperature, the pearlite decomposes to form a dispersion of carbides in a ferrite matrix. Similar effects occur in carbonmolybdenum and carbon...
