High fatigue resistance. this is an important property, since stone saw blades are frequently exposed to high and varying loads as well as to vibrations i.e. high fatigue stresses. High transition temperature, resulting in less risk of undesirable martensite formation during the brazing of the diamond segments. A chemical composition which minimizes the risk of cracks in connection with brazing. Good flatness and straightness. Square, smooth edges which is a pre-requisite for strong & durable joint between the parent blade & segments.
