Assab Steels 709M Machinery Steel Category : Metal , Ferrous Metal , Alloy Steel Material Notes: ASSAB 709M is an alloyed machinery steel with high strength in small and medium sizes. As standard ASSAB 705M is supplied tough hardened requiring no further heat treatment. It can be oil hardened to higher mechanical properties. Applications: ASSAB 709M is suitable for flame and induction hardening. It can also be nitrided or tuffrided to a surface hardness of 600-650 Vickers.ASSAB 709M is not suitable for welding but can with certain precautions be repair welded.Typical applications include shafts and other power transmission components as well as high strength bolts.
