Abstract
The present invention relates to a hot-rolled steel sheet applied as a material for home appliances, vehicles, or the like and, more specifically, to a hot-rolled steel sheet having excellent workability and anti-aging properties and a method for manufacturing the same. To this end, the present invention uses ultra-low carbon Al-killed steel so as to optimize the alloying elements thereof and the manufacturing conditions, thereby providing hot-rolled steel sheets having both excellent workability and anti-aging properties.
