1.7220 (DIN EN ISO 683-7 : 2025-02) 34CrMo4 1.7220 DIN EN ISO 683-7 : 2025-02 Supersedes DIN EN 10277 : 2018-09 Valid Germany 34CrMo4 1.1.1 1)
1) Remark: The alloy quenched and tempered steel is applicable for parts with high strength and high toughness requirements at mean and higher heat-treatment cross sections in vehicle manufacturing, engine and machine engineering (e.g. shafts, gear wheels, steering knuckles). The steel shows high resistivity to static and dynamic loading.
