The amount of carbon in stainless steel must be lower than that in carbon steel or lower alloy steel (i.e., steel with alloying element content below 5%). While electric arc furnaces (EAF) are the conventional means of melting and refining stainless steel, VOD is an economical supplement, as operating time is reduced and temperatures are lower than in EAF steelmaking.
30-2 and SR 26-4, have been produced by cost-saving steel making process called the "SS-VOD process". The chemical compositions of the steels are characterized by reducing C and N contents to extremely low levels to and by addition of Nb to
