1.0726 (DIN EN 10087 : 1999-01)	1.0726	DIN EN 10087 : 1999-01	DIN EN 10087 : 1999-01 replaced by DIN EN ISO 683-4	Replaced	Germany	35 S 20	35S20	The free-cutting tempered steel 35S20 is used for bulk parts of mean strength, especially for lower requirements to ductility in transversal direction opposite to comparable C-steels (e.g. C35). Increased cutting speed represents an advantage, the increased cracking risk at rising C-content has to be considered. 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).
