The gaseous oxygen is more effective for the decarburization of Ni-Cr alloy and 18-8 stainless steel in Heroult type electric are furnace making process than iron ore. and it reduces the loss of Cr amount as the Cr-oxide states.
The rate of decarburization of 18-8 stainless steel is 0.84% C/hr in the initial oxygen blowing period, after then it is increased by the diffusion of FeO and C and is decreased by the increasing of the MgO contents in slag.
