| Abstract: | As compared to traditional carbon steel, hot rolling automobile structural steel SAPH 400 boasts of bether cold forming properties, because of addition of Re wire to change the inclusions. Its microstructure includes ferrite and a small quantity of pearlite without obvious banded structure. Besides, the steel is characterized by pure components, uniform microstructure, moderate granule, excellent performance, an ideal material to make car frames. |
