What reading level is The American Steel Worker a Twenty Five Years Experience in the Selection Ann book?
To quickly assess the difficulty of the text, read a short excerpt:
If run the same length of time as those made of the first stock used, they would break very easily, but when run only 25 minutes gave very good satisfaction.
In many shops it is customary to make snap gauges of machine steel. They are much easier made, the cost of material is less, and, if hardened properly, they will wear well. It is best, in cases of this kind, to use open hearth steel rather than Bessemer, as the latter runs more uneven. The best results will be obtained if we use as packing... material granulated leather instead of bone. When packing, mix with an equal amount of granulated charcoal, run five or six hours, if the gauge is % inch thick or more. Run at a very low heat, and dip in the oil bath. It will be found to be very hard, and probably straight. If hardening small pieces, it is advisable to use smaller boxes than when large pieces are being treated, as it takes some time to heat a large box through. Pieces near the walls of the box will become hot quicker than those in the center, and consequently will be hardened deeper.
