It is seldom necessary to temper or reduce the hardness of steel bushes, rings, or collars; because the generality of these kinds of articles are required for bearings for different parts of machinery, where they have to endure a great amount of friction, consequently they require to be very hard to keep them from wearing. Ring and plug gauges, which are made of steel, require a great amount of hardness given to them to prevent them from wearing; consequently these kinds of articles will not, after hardening, require to be tempered.
