The steel SS1370 with composition must first be carburized and then hardened. It is desired to obtain a hardness HV of 550 at a depth of 2.5 mm below the surface. The carburization takes place in almost pure carbon monoxide. This means that the austenite will be saturated with carbon during carburization. At a temperature of 950C, this corresponds to a carbon content of 1.37 wt%. Calculate the time required to complete the process. Fe Bal.
