Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification
1.0737 (DIN EN ISO 683-7 : 2025-02) 11SMnPb37 1.0737 DIN EN ISO 683-7 : 2025-02 Supersedes DIN EN 10277 : 2018-09 Valid Germany 11SMnPb37 1.1.1 1)
1) Remark: High-performance free cutting steel of excellent machining properties. Not intended for heat-treatment. Deteriorating ductility qualities due to increased S-content and higher cracking risk have to be considered. It shows better cutting performance compared to 11SMn37. According to this standard it will be delivered as levelled and bright steel sheared to length in the drawn, peeled or grinded condition.
