Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification
1.1158 (DIN EN ISO 683-1 : 2018-09) C25E 1.1158 DIN EN ISO 683-1 : 2018-09 Supersedes DIN EN 10083-2 : 2006-10 Valid Germany C25E 1.1.1 1)
1) Remark: Steel C25E is suitable for low loaded parts of higher dimension and more complex form as well as higher demands on uniformity of properties and surface appearance (e.g. transmission parts, crankshafts).
