| Abstract: | Relationship between tensile property and chemical composition of 20MnSi steel is obtained through regression analysis. It is discussed that tensile strength should be applied as boundary limitation in compo-sition design when C<0. 27%. Reject rate is also estimated on middle C, Mn content under current control level. |
