Material Description

Material Number Material Name Material Number (single) Standard Standard Status Country VDA 231-106 classification
1.7979 (SEW 605 : 2019-07) 18MnCrMoV6-4-8 1.7979 SEW 605 : 2019-07 Valid Germany 1.1.1 1)
1) Remark: Bainitic steel Bainidur® 1300 (patented by Deutsche Edelstahlwerke Specialty Steel, Witten) with high strength and toughness; continuously air cooled from the forming heat, with the advantages of quenched and tempered steel in short process chains. It is excellent suitable for case hardening and carbonitriding. Application: cost-optimized structural components in automotive engineering
