Abstract
PURPOSE:To obtain a high-strength and inexpensive belt block for non-stage transmission, by subjecting a high-carbon steel sheet for heat treatment which contains specific amounts of C, Si, Mn, P, S, Al, and Cr and in which graphite in a state of fine lumps is uniformly dispersed to blanking and then to heat treatment. CONSTITUTION:A high-carbon steel sheet for heat treatment which has a composition containing, by weight, 0.50-1.50% C, 1.30-2.00% Si, 0.70-1.00% Mn, <=0.02% P, <=0.01% S, 0.005-0.015% Al, and 0.01-1.00% Cr and also has a microstructure in which lumpy graphite of 5-50mum comprises >=80% of C and the remaining C is formed into spheroidal cementite of <=5mum and they are uniformly dispersed in a ferritic matrix is blanked and then subjected to heat treatment. By this method, the V belt block for belt driven-type non-stage transmission having high strength and dimensional accuracy can be obtained with high mass productivity.
