High carbon steel products must frequently be annealed without decarburization.At annealing temperatures,CO2 and H2O readily react with carbon in the steel to form CO and H2.Hydrogen itself can cause decarb,forming methane.Depending on temperature,the carbon in the steel can be present as cementite or as solute in the - and -iron phase.Each of the forms requires different atmosphere People also askWhat is decarburization of steel?What is decarburization of steel?Decarburization is a surface degradation phenomenon in the forging and heat treating of steels.Decarburization may be described as a metallurgical process in which the surface of steel is depleted of carbon by heating above the lower critical temperature or by chemical action.Decarburization Metallurgical Processes
