Abstract
The heat-treatment conditions which exert influences on the hardness and the toughness of high carbon chromium steel quenched, and quenched and tempered at low temperatures, were studied. The toughness were measured by bending test. The heat treatment condition which gives the highest bending strength under definite hardness was found. Of the specimens with the hardness above Rc 62, the specimen of steel having lamellar pearlite structure before hardening gave best results. There are various combination of hardening and tempering temperature to get the expected hardness of specimen, because the hardness after hardening is different according to the quenching temperature. When a hardness below Rc 60 is expected, the lower the quenching temperature the higher the toughness. The bending strength depends exclusively on the hardness of specimen, whatever combination of tempering temperature and holding time may be applied when quenched from 840°C. In this investigation, it was confirmed that there is a brittleness point at the tempering temperature about 180°C.
