Steelmaking process

摘要

A process for producing a steel having a chemical composition of a type 420 stainless steel includes subjection at least a portion of a melt of the steel to electroslag remelting and, in a subsequent step, heating the steel to a temperature at least as great as the lowest temperature at which all carbides that can form in the remelted steel will dissolve and no greater than the nil ductility temperature of the remelted steel, and maintaining the temperature for a period of time sufficient to dissolve primary and clustered carbide particles in the remelted steel greater than 15 micrometers in length.
