Properties: No data
Applications: ASSAB 705 is an alloyed machinery steel with good hardenability also in large cross sections. It combines high strength with best toughness. ASSAB 705 is intended for use in the as-delivered condition, requiring no further heat treatment. However, it can be oil, water or polymer hardened to higher hardness and higher mechanical properties if required. ASSAB 705 is suitable for induction hardening and can also be nitrided or tuftrided to a surface hardness of 600-650 Vickers.
Reference: Not shown in this demo version.

Heat Treatment
Hardening: 880-935 C, water.
Tempering: 600-670 C, air.
Diagram note: Quenching in water after induction heating at 880 C.
