| Abstract: | In this paper, the data of heat analysis and product mechanical properties were analyzed using multivariate regression analyses. The results show that with controlled the chemical composition, compared to standard requirements, the average tensile strength increased by 15. 2 %, yield strength by 5. 4% and elongation by 16%. |
