| Abstract: | The synthetically physics and chemistry report of high strength grey iron castings for marine that are producted by our institute are analyzed. It gives average levels and distributions of degree of normality RG, relative hardness RH and quality index Q_i for this materials and compares them with the advanced level of our country and overeas. The effect of chemical composition on quality target of grey irons is analyzed in the end of the paper. |
