Cold rolled steel sheet hardness.

Commercial steel ds types a b and c. Cold rolled commercial quality sheet or coil steel supplied for either exposed or unexposed applications where bending welding forming or moderate drawing is involved. Choose from our selection of cold rolled steel including low carbon steel sheets and bars low carbon steel rods and discs and more. This is a prime quality low carbon cold rolled commercial finish steel sheet which has been cold reduced to gage and hardness as indicated.

Compared to hot rolled steel cold rolled steel has a nearly 20 increase in strength through the use of strain hardening. As you might suspect the manufacturing process behind cold rolled steel is a bit different. 0 381 3 429 mm and widths to 80 in. Cold rolled steels are available in thicknesses from 0 015 0 135 in.

Despite the name this process refers to steel that is pressed with the pressure of a roller at room temperature. Cold rolled steel is stored and sold in coiled form after rolling. Crcq is available in coil sheet or strip formed with various gauge ranges widths and hardness. In addition to improvement of mechanical properties the cold rolling produces steel plate sheet of the desired physical dimensions.

Customers often ask us about the differences between hot rolled steel and cold rolled steel there are some fundamental differences between these two types of metal the differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill and not the product specification or grade. Steel comes in many grades specifications shapes and finishes the world steel association lists over 3 500 different grades of steel each with unique properties. The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications. Cold rolling increases the strength and hardness and decreases ductility of steel by rolling it at ambient temperature or below its recrystallization temperature.

Chemically it is very similar to a36 hot rolled steel but the cold rolling process creates a better surface finish and better properties. It is priced lower than genuine cold rolled strip steel. 2032 mm depending on dimensions and product quality.
