Square bar rolled 70 mm 1.0503 - C45 - 12 050
1.0503 (C45) is classified as an unalloyed structural steel. It is a medium-carbon steel widely used in mechanical engineering for stressed components. It offers higher strength compared to mild structural steels (such as S235, S355), while maintaining good machinability and suitability for heat treatment (quenching, tempering, surface hardening).
