Mar 07, 2007 · It can have a very strong tractor tire tread grain when trying to finish. Seems that hot rolled is just a bit more dense. In steel going to be used forging, it probably doesn't matter. You can improve on the grain in cold rolled by forging, but hot rolled is damed good just as it comes form the mill. There is a lot of talk about grain refinement. High Carbon Steel Strips Pessina AcciaiHigh carbon annealed cold rolled steel strips are used in production of different items that must be hardened and tempered after blanking or stamping. In relation of final application, Customer is supported in choosing best steel grade and properties. For most severe applications, please refer to alloyed steel Hot Rolled Low Carbon Steel - Hot Rolled Low Carbon Steel Hot Rolled Low Carbon Steel Specifications Hot-Rolled low carbon steel has been rolled at high temperature from a cast steel slab more than two inches thick into steel coil as thin as 1/16 of an inch thick. Because the steel is rolled hot, and the reduction from slab to coil is great, the coil surfaces are noticeably rough and slightly oxidized.
Mar 19, 2014 · Hot Rolled Steel is softer and more pliable than Cold Rolled Steel. Hot Rolled Steel has a light- grey, rough finish and rounded edges (in Flat and Square Bars), and Hot Rolled products are typically oversized. Hot rolled steel vs cold rolled steel - what's the difference?Mar 26, 2019 · Hot rolled steel Hot rolled steel is easier to make, to shape and form. It has its source in a mill process involving rolling the steel at high temperature. It starts from a piece of still billet which is heated up 1700 degrees Fahrenheit (926° Celsius) and then the steel is rolled through the mill into the particular shape. Hot-Rolled Steel McMaster-CarrEasy-to-Weld A572 AlloySteel Sheets and Bars.
