Abstract
PURPOSE: To obtain the titled casting under a so called as-cated condition without performing any heat treatment after casting, by forming a thickness so that is will be cooled at a cooling rate which is faster than a prescribed one, and, at the same time, by performing the casting so that chemical elements other than Fe and impurities may be specified.
CONSTITUTION: A casting composed of 3.5W4.2% C, 2.0W3.3% Si, ≤1% Mn, 0.03W0.20% Sn, 0.02W0.06% Mg, and the rest of Fe and impurities, is manufactured by the following method. That is to say, when the casting is formed so that is may have the above mentioned chemical composition, and when the thickness is formed so that the casting may have ≥13/sec cooling rate, a spheroidal graphite cast iron casting having 50W90% pearlite ratio may stably be obtained even under an as-coated condition. As the result of this, small parts for automobile, etc., can be manufactured under an excellent working environment and any energy saving condition.
