Material Description

Material Number Material Number (single) Standard Scope Standard Status Country Predecessor VDA 231-106 classification
5.2100 (DIN EN 16079 : 2024-03) 5.2100 DIN EN 16079 : 2024-03 Supersedes DIN EN 16079 : 2012-02 Valid Germany EN-GJV-300 1.2 1)
1) Remark: Ferritic compacted (vermicular) graphite iron with the lowest strength and highest ductility. The high thermal conductivity and the low Young's modulus reducing the thermally induced stress. The predominantly ferritic matrix reduces the expansiongrowth, when the component is exposed to elevated temperature. Application: exhaust manifolds, turbocharger housings, cylinder heads for large marine engines and stationary engines
