DIFFERENCE BETWEEN HOT ROLLED PROFILES AND COLD ROLLED PROFILES
A variety of methods can produce stainless steel profiles , all of them offering different benefits. Hot rolled profiles have some very specific characteristics as well. Rolling of profiles can take place at high temperatures (hot rolling) or at room temperature (cold rolling). The temperature plays a significant role in regards of the result. With both production technologies, it is possible to produce either hot rolled profiles or cold rolled profiles in stainless steel. However, the properties of both methods show distinct differences. Hot Rolled Profiles – When Stainless Steel Heats Up Hot rolling of sections is the most productive technology of manufacturing long bars. Once the mill is set-up and ready for the production process, it can hot roll profiles in huge amounts with high productivity. In general, the temperature rises above 1.100 degrees Celsius. So the billets or blooms for the traditional “start-stop”-production method or wire rods for “endless” rolling ...
