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 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 method heat up to this level. Several roll stands deform them plastically. The geometry and lengths of the desired finished hot rolled profiles determinate the dimensions and weight of the raw material.
The raw material for cold rolling profiles is wire rod, which is a semi-finished product. The diameter of the rod depends also on the cross section of the final product. Similar to the endless hot rolling, cold rolling is also a continuous process, but at room temperature. The prodcution machinge leads the wire through different stands and so creates the desired shape with many passes. This process decreases the grain of the metal, the material becomes harder and the surface smoother and more shiny.
