General for 30HGSA/30CrMnSiA hollow steel
30HGSA is a steel for quenching and tempering, which has a good combination of strength and
toughness in the quenched and tempered condition. After oil quenching it will be through hardened
up toØ60 mm bar diameter. The micro structure of bigger dimensions is not fully martensite. The
steel is applicable to induction hardening. The surface hardness will exceed min. 53 HRC. 30HGSA
can be delivered M-treated in order to optimise the machinabilty.
Standard
This product specification is based on EN 10083-3:2006 and the steel will meet the requirements of
this standard.
