A system and method of cladding a carbon steel piece with stainless steel according to which the carbon steel piece is cleaned, heated, coated with the stainless steel, and strengthened. In an exemplary embodiment, coating the carbon steel piece with the stainless steel includes melting the stainless steel, atomizing the melted stainless steel, and spraying the atomized stainless steel so that at least a portion of the atomized stainless steel is deposited on the carbon steel piece to thereby coat the carbon steel piece with the stainless steel.

System and method for stainless steel cladding of carbon steel pieces

An injector for injecting particulate material into a metallurgical furnace has a first tubular barrel and a housing defining a chamber having an inlet for particulate material, a first gas inlet and a particulate material/gas outlet connected to the rear end of the first barrel. The first air inlet has a first nozzle operable to inject gas into the chamber at a supersonic velocity when gas at suitable pressure is passed through the nozzle. A second tubular barrel surrounds the first barrel in spaced relationship therewith. The second barrel has a second gas inlet adjacent its rear end and a second nozzle adjacent its front end. Gas under pressure supplied to the second gas inlet passes between the barrels and is discharged at supersonic velocity from the front end thereof adjacent gas and entrained particulate material discharged from the first barrel so as to shroud the particulate material.
