West Yorkshire Steel are suppliers of bright drawn bar and hot rolled black bar. 708M40 is a similar grade to 709M40 but with a variation in the molybdenum content. As a high quality alloy steel specification 708M40 is usually supplied heat treated to ‘T’ condition. This grade offers good ductility and shock resisting properties combined with resistance to wear. With these characteristics it is a popular high tensile engineering steel with a tensile of 850°-1000N/mm². At low temperatures it has reasonably good impact properties. It is also suitable for a variety of elevated temperature applications. For maximum wear and abrasion resistance the steel can be nitrided to give a shallow depth wear resistant case. Flame or induction hardening of 708M40T can give a case hardness of 50HRc or higher.
