Material Description

Material Number Material Name Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification
1.7323 (DIN EN ISO 683-3 : 2022-06) 20MoCrS4 1.7323 DIN EN ISO 683-3 : 2022-06 Supersedes DIN EN ISO 683-3 : 2019-04 Valid Germany 20MoCrS4 1.1.1 1)
1) Remark: Steel 20MoCrS4 is suitable for parts in vehicle manufacturing and machine engineering, which are wear loaded at mean core strength, high ductility and fatigue strength. It also shows an enhanced workability (gear wheels, axles, shafts).
