Material Description

Material Number Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification
1.0718 (DIN EN ISO 683-4 : 2018-09) 1.0718 DIN EN ISO 683-4 : 2018-09 Supersedes DIN EN 10087 : 1999-01 Valid Germany 11SMnPb30 1.1 1)
1) Remark: Free-cutting steel 11SMnPb30 is not intended for heat-treatment and is preferred 11SMnPb30 for higher machinability and surface appearance demands. Steel 11SMnPb30 shows lower crack sensitivity compared to higher S-containing steels (11SMn37, 11SMnPb37). Application for bulk parts in car industry as well as in apparatus and equipment engineering.
