What is the Fe-C phase diagram of steel?

Iron–Carbon Phase Diagram • In their simplest form, steels are alloys of Iron (Fe) and Carbon (C). • The Fe-C phase diagram is a fairly complex one, but we will only consider the steel and cast iron part of the diagram, up to 6.67% Carbon. 3. Fe – C Equilibrium DiagramSee all results for this questionsp.info What is the percentage of carbon in Fefe-C alloy?Fe-C alloy contains 0.83% carbon. In stainless steel, the S points are moved to the left due to chromium, the steel with 12% chromium and 0.4%+ carbon as well as steel with 18% chromium and 0.3%+ carbon belongs to hyper-eutectoid steel.See all results for this questionsp.info What is Fe-C phase in heat treatment?In heat treating of steels, the liquid phase is always avoided. The steel portion of the Fe-C phase diagram covers the range between 0 and 2.08 wt. % C. The cast iron portion of the Fe-C phase diagram covers the range between 2.08 and 6.67 wt. % C.See all results for this questionsp.info Why is Fe-C alloy not suitable for heat treatment?Because there is no free ferrite in the structure, the mechanical performance is higher than the above steel, but the thermal sensitivity of heat treatment is low.
