Which Grinding Wheel Should I Choose? | Norton

The type of material affects the selection of abrasive, grit size and grade. Alumina type abrasives are the most suitable for grinding high tensile materials such as steel and ferritic cast irons. The more friable types of alumina are preferred on harder steels and applications having large arcs of contact.

How to choose the grinding wheels for stainless steel ...

3.4 Selection of hardness of grinding wheel When grinding stainless steel, low hardness grinding wheels are used with better self-sharpening. When the hardness is too low, the abrasive grains are not firmly bonded and fall off before being blunt, which will greatly reduce the service life of grinding wheels for stainless steel.

Grinding Out Hardened Parts | American Machinist

A corundum grinding wheel is adequate for the external grinding of the cone. To complete internal-cylindrical grinding in the shortest possible time, a CBN grinding wheel, capable of being dressed at a peripheral speed of 60 m/sec, is used. The CBN grinding wheel is re-profiled after every 100 work-pieces.

Correct grinding wheel material for hardened steel ...

I do know a rule of thumb with grinding wheels is a hard wheel for soft materials, and a soft wheel for hard materials. You want something fairly friable for hard stainless to reduce heating caused from rubbing with dull abrasive. You probably shouldn't be thinking "durable" you should be thinking "cool".
