I have this article bookmarked. It is fairly technical but has some clear statements in everyday English, for example "high thermal stability makes CBN the superabrasive of choice for the grinding of all varieties of steel alloys--an area where diamond abrasives are not normally employed. Even with a melting point of 4,000ƒC, which is the highest of all materials, diamond has substantial thermal limitations in many grinding applications: " and the list that follows.

Basically, diamond appears to be not recommended for grinding steel at high speeds, i.e., on a bench grinder.
