Assab Steels 705M Machinery Steel
Categories:	Metal; Ferrous Metal; Alloy Steel
Material Notes:	ASSAB 705M is an alloyed machinery steel with good hardenability also in heavier sizes. As standard ASSAB 705M is supplied tough hardened with no further heat treatment required. It can be oil hardened to higher mechanical properties if required. Applications: ASSAB 705M is suitable for induction hardening and can also be nitrided or tuffrided to a surface hardness of 600-650 Vickers. ASSAB 705M is not suitable for welding but can with certain precautions be repair welded. AISI /SAE 4340, DIN 34CrNiMo6, W.nr. 1.6582, BS 817M40 (EN 24), AFNOR 35NCD6, JIS SNCM8, SS 2541
