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.

410 mpa as shown in table 2 page 3. However after the cold reduced product is annealed heated to high temperatures it becomes very soft and formable. With these two products the cold rolled product has low carbon content and it is typically annealed making it softer than hot rolled sheet. However this cannot be said about cold rolled sheet and hot rolled sheet.

Materials ranging from the sheet metal in cars to the tubing in bicycle frames can be created from cold rolled steel. Thus the sheet not only becomes thinner but also becomes much harder less ductile and very difficult to form. 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.

Crcq is available in coil sheet or strip formed with various gauge ranges widths and hardness. 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. In stock and ready to ship. 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.

Commercial steel ds types a b and c. See table 3 page 3. The most commonly available of the cold rolled steels it has a good combination of all of the typical traits of steel strength some ductility and comparative ease of welding and machining. The cold reduction operation induces very high strains work hardening into the sheet.

This is a prime quality low carbon cold rolled commercial finish steel sheet which has been cold reduced to gage and hardness as indicated. 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.
