LOW YIELD HOT-ROLLED STEEL PLATE HAVING EXCELLENT WELDABILITY AND METHOD FOR MANUFACTURING THEREOF

摘要

The present invention relates to a low yield hot-rolled steel plate having excellent weldability and a method for manufacturing the same and more specifically, to a low yield hot-rolled steel plate having excellent weldability which has a yield ratio lower than 0.75 by optimizing the steel component and hot roll texture, and which has excellent integrity at a welding portion during an electric resistance welding process.
