Material Description

Material Number	Material Number (single)	Standard	Range of Application	Standard Status	Country	Predecessor
1.0737 (DIN EN ISO 683-4 : 2018-09)	1.0737	DIN EN ISO 683-4 : 2018-09	Supersedes DIN EN 10087 : 1999-01	Valid	Germany	11SMnPb37	1)
1) Remark: Free-cutting steel 11SMnPb37 is not intended for heat-treatment and is one of the maximum demand free cutting steels due to its excellent machinability properties. Reduced ductility properties and increased cracking risk due to the higher S-content have to be considered. 11SMnPb37 shows compared to 11SMn37 higher parameter. Application for bulk parts in car industry, apparatus and equipment engineering.
