Re: [MW:6105] Why carbon steel does not used after temperature 343 deg.c

Prolonged exposure of carbon and low alloy steel components to temperatures exceeding 800 °F (427 °C) can result in several kinds of material microstructural deterioration; for example, creep cavitation, carbide coarsening and/or spheroidization, and, less commonly, graphitization. Graphitization generally results from the decomposition of pearlite (iron + iron carbide) into the equilibrium structure of iron + graphite and can severely embrittle the steel when the graphite particles or nodules form in a planar, continuous manner.
