Sawing of marble, granite and other species of rocks for the building industry and other purposes is carried out to large extent in stone gang saws with diamond segmented blades. Up to 100 saw blades can be fitted in a single set-up.

The demands made on stone sawing call for straight cuts, high cutting speed and maximum utilization of the expensive diamond-segmented saw blades.

Agrawal Gang saw steel meets the demands made by saw blade manufacturers and consumers on the quality of the blade material. Some characteristic properties of Agrawal gang saw steel are:-

• 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 marten site 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.

Agrawal maintains a high and uniform quality, delivery after delivery and are supplied in two finishes i.e. Bright & Super blue.
