1.0757 (DIN EN 10087 : 1999-01)	1.0757	DIN EN 10087 : 1999-01	DIN EN 10087 : 1999-01 replaced by DIN EN ISO 683-4	Replaced	Germany	45 SPb 20	46SPb20	The free-cutting tempered steel 46SPb20 is used for bulk parts of higher strength, especially for lower requirements to ductility in transversal direction opposite to comparable C-steels (e.g. C45). Machinability enhancement is achievable by Pb-content. Application in auto industry, as well as in apparatus equipment and machine engineering (e.g. screws, nuts, small-size parts). As bright steel product it is used in the form of bars, bright, straight, in various conditions (see DIN EN 10277 : 1999-10).
