Abstract
The invention relates to a process for obtaining steels having improved machinability. This process provides for the upgrading of divided metallurgical products, which are consolidated without fusion, with incorporation of a dispersed phase. This process is used in particular for scrap consisting of sheet metal or turnings, which is mixed in the desired proportion with an additive such as for example sulfur or lead. After it has been compressed the mixture is extruded in a press in the form of bars and the like. This process is particularly suitable for producing stainless steels containing sulfur or lead. The lead stainless steels thus prepared have an excellent corrosion resistance, in addition to their machinability characteristics.
