1.0718 (DIN EN 10277-3 : 2008-06) 11SMnPb30 1.0718 DIN EN 10277-3 : 2008-06 DIN EN 10277-3 : 2008-06 replaced by DIN EN 10277 : 2018-09 Replaced Germany 11SMnPb30 11SMnPb30 1.1.1 1)
1) Remark: Free cutting steel 11SMnPb30 is unsuitable for heat-treatment and is preferred to steel 11SMn30 for higher requirements to machinability and surface appearance. 11SMnPb30 shows a lower cracking sensitivity compared to steel with a higher S-content (11SMn37, 11SMnPb37). It will delivered as levelled and bright steel sheared to length in the drawn, peeled or grinded condition.
