Hot rolling is done at high temperatures (over 1700\u02daF), resulting in steel which is easier to shape, but has a rough, scaly surface. Cold rolling occurs after the steel has already been hot rolled. The steel is then rolled again at room temperature, forming steel which has higher precision, higher strength, and a smooth, more refined finish.<\/p>\n\n\n\n<p>The main difference between hot rolled and cold rolled steel is in how they are processed. The difference in processing directly affects their shape and properties<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">\uc5f4\uc5f0\uac15\ud310\uc774\ub780
