Cold Rolled Steel Sheet Hardness

It is recommended and generally used in applications where sheet steel s broader chemical and physical tolerances will permit.

Cold rolled steel sheet hardness.

In stock and ready to ship. Cold rolled steels can also be specified as dent resistant dr or bake hardenable bh for applications that require dent resistance after forming and painting. Thus the sheet not only becomes thinner but also becomes much harder less ductile and very difficult to form. The finished material appears dark gray and has a smooth reflective surface that is resistant to corrosion thanks to a stable oxidation film on the surface of the finished steel.

For high strength or structural applications cold rolled steels are also available in yield strengths up to 60 ksi. Commercial steel ds types a b and c. See table 3 page 3. Materials ranging from the sheet metal in cars to the tubing in bicycle frames can be created from cold rolled steel.

As noted in an earlier post different types of steel undergo a wide range of processes to achieve the proper physical properties many people have heard that there s a difference between hot and cold rolled steel but don t understand what how the production of hot rolled or cold rolled steel is different from one another what industries and applications hot rolled and cold rolled serve. The cold reduction operation induces very high strains work hardening into the sheet. 410 mpa as shown in table 2 page 3. Choose from our selection of cold rolled steel including low carbon steel sheets and bars low carbon steel rods and discs and more.

Cold rolled commercial quality sheet or coil steel supplied for either exposed or unexposed applications where bending welding forming or moderate drawing is involved. It is priced lower than genuine cold rolled strip steel. However after the cold reduced product is annealed heated to high temperatures it becomes very soft and formable. Crcq is available in coil sheet or strip formed with various gauge ranges widths and hardness.

This is a prime quality low carbon cold rolled commercial finish steel sheet which has been cold reduced to gage and hardness as indicated. However this cannot be said about cold rolled sheet and hot rolled sheet.
