Material Description

Material Number Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification
1.0535 (DIN EN ISO 683-1 : 2018-09) 1.0535 DIN EN ISO 683-1 : 2018-09 Supersedes DIN EN 10083-2 : 2006-10 Valid Germany C55 1.1 1)
1) Remark: Steel C55 is suitable for higher loaded parts requiring enhanced wear resistance in vehicle manufacturing, engine and gear engineering. Preferred application for parts undergoing a surface hardening, lower risk of tearing for larger and more complex components than C60 (e.g. gear wheels, shafts, indented roller).
