Hot rolling and cold rolling are the two core forming processes for steel plates and profiles. **Hot rolling vs cold rolling** directly determines the microstructure, mechanical properties, surface quality and final service performance of steel materials. Most people only tell them apart by surface appearance. However, hot rolling vs cold
