Material Description

Material Number	Material Number (single)	Standard	Scope	Standard Status	Country	Predecessor	VDA 231-106 classification
1.0718 (DIN EN ISO 683-7 : 2025-02)	1.0718	DIN EN ISO 683-7 : 2025-02	Supersedes DIN EN 10277 : 2018-09	Valid	Germany	11SMnPb30	1.1	1)
1) Remark: Free-cutting steel, not intended for heat-treatment, 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.
