A flame cut plate edge has a radically different surface finish than a ground surface, for example. Choosing a process thats capable of achieving the desired surface finish is the first step in figuring out how to manufacture a part that requires a particular finish.

Hot Rolled vs Cold Rolled Steel - SPACO

Jul 09, 2020 · Cold finish bars can be drawn, turned or ground and polished but they are not rolled." But , for the rest of this article, I won't differentiate between die drawing and rolling. I don't doubt what the gentleman has to say, because I have never been in a cold finish bar mill, but I do know that at least some HOT finish bar mills do use rollers. How to Harden Steel:10 Steps (with Pictures) - wikiHowFeb 19, 2021 · 1. Fill a heat-safe container with water or oil deep enough to submerge your steel. Use a coffee can or similarly shaped container as your quenching chamber. Pour in water or vegetable oil so its 23 inches (5.17.6 cm) from the rim of the container. Make sure the oil or water is at room temperature.

Hot Rolled, Cold Rolled and Cold Drawn Steel - a Quick

Commonly cold-rolled products often include similar hot rolled products like sheets and bars, but are usually smaller. Cold Drawn Steel Like cold rolling, cold drawing is performed at room temperature, but instead of producing a flat object like a coke can, cold drawing makes steel into the form of a wire like the spokes of a wheel or a paper clip.
