Steel sheet with high silicon content has low brittleness and low plasticity, and needs to be preheated to 200 °C before cold rolling.

The process of creating cold rolled steel begins with hot rolled P&O. The hot rolled P&O is sent through a cold reduction process which creates a thinner thickness and a harder surface. This also makes the steel difficult to form. The steel is then sent through an annealing process which consists of a heat treatment to increase ductility. Cold Rolled Steel AK SteelCold Rolled Steels are available in thicknesses from 0.015 0.135 in. (0.381 3.429 mm), and widths to 80 in. (2032 mm), depending on dimensions and product quality. Difference Between Hot and Cold Rolled Steel Metal Sep 11, 2014 · Cold Rolled Steel. Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling.
In cold rolling, steel sheet is cooled at room temperature (after hot rolling), and is then annealed and/or tempers rolled. Although cold rolled steel is a specific type of steel, the term is often used to mean all types of carbon steel materials. Common specifications for CR steel include ASTM A653, ASTM A879 CQ, ASTM A1008, and CQ SAE 1008. Steel Plate What is a Cold-Rolled Steel? - Definition from CorrosionpediaMar 09, 2016 · Cold-rolled steel contains a low carbon content, and an annealing method makes them softer than hot-rolled sheet. Cold-rolled steel products are commonly produced in sheets, strips, bars and rods. Cold-rolled products are generally smaller than the same products produced by a hot-rolled method. Cold-rolled steel sheets and strips are available in full-hard, half-hard, quarter-hard and skin-rolled What's Cold Rolled Steel Cold Rolled Steel Sheet - SongshunBefore the rolling, the cold rolled steel sheet does not get through heat treatment processing. The production line for cold rolling is long with many machines and complex technics. And because of the steel surface is easily get the oxidized scale in the high-temperature condition, the surface of hot rolling steel is raggedness. So must use the steel with a clean surface, good shape and mechanical properties, take hot rolled product as material to produce it with cold
P, V and S element is a little different each other, machinery property is similar. 42CrMo4 is from European standard-EN10083, 42CrMo4 is a kind of alloy steel with high hardenability, good toughness and small deformation during quenching. It has high creep strength and endurance strength at high temperature. 42CrMo is from China GB/T standard steel grade, it is a medium carbon alloy structural
