 note = {application/pdf, The heat treating conditions were discussed in this investigation as concerned to the hardening the small mass of 0.6%C steel, such as needle-block of a carding machine (a sort of spinning machine). The three points bending test were carried out to examine the toughness of heat treated specimen. Results are summarized as ;  1)The hardness of above 800 VHN is obtained by quenching from just above A3 transforming temperature, when the holding time is 60 sec. The higher temperature is required as the holding time is reduced.  2)The toughness is decreased with raising the quenching temperature and prolonging the holding time due to the growth of austenite grain.},
