WebWhen the carbon content of steel is above 0.3 percent, the material will become very hard and brittle if it is quenched in water from a temperature of about 850° to 900° C (1,550° to 1,650° F). The brittleness can be decreased by reheating the steel within the range of 350° to 500° C (660° to 930° F), in a process known as tempering. WebThere are many methods used to heat treat steel, including but not limited to: Annealing - Heating and then slowly cool steel to refine it and make it softer Carburizing - Adding carbon to the surface with heat and carbon-rich substances Case hardening - Carburizing and quickly cooling steel to keep the center soft while the rest hardens cities with rivers through them
