Cold Reduced Steel Sheet

This process is called work hardening.

Cold reduced steel sheet. To about in. Jis g3141 cold reduced carbon steel sheets and strip. Cold rolled steel sheet and coil dc01 bs en 10130 2006 cold rolled steel often referred to as cold reduced or cr is a low carbon product produced using raw material such as coke and coal at steel mills through out the world. Sheet quality finish cold rolled steel will have closed thickness profile good surface texture and flatness compared with hot rolled steel.

Thus the sheet not only becomes thinner but also becomes much harder less ductile and very difficult to form. Steel warehouse uses a reversing mill and a complex automation system to target precision gauge points. Our cold rolled steel sheet has been cold reduced to the specified thickness and subsequently annealed and temper rolled to achieve the desired characteristics. Cold rolled steel reduction is the process of reducing thickness of hot roll pickled strip to lower target gauge points.

Before becoming a cold rolled product it is effectively hot rolled steel which then under goes further processes. These types of sections are cold formed from steel sheet strip plate or flat bar in roll forming machines by press brake or bending operations. Cold reduced steel sheet cold reduced steel is so cold because of its production at room temperature. Our cold reduction mill services make steel harder and stronger.

The material thicknesses for such thin walled steel members usually range from 0 0147 in. However after the cold reduced product is annealed heated to high temperatures it becomes very soft and formable. Cold formed steel members have been used also in bridges storage racks grain bins car bodies railway coaches highway products transmission towers transmission poles drainage facilities firearms various types of equipment and others. The first process is the cold reduction.

Usually steel sheets are manipulated at very high temperatures. The cold reduction operation induces very high strains work hardening into the sheet. Our cold rolled steel sheet is used in a broad range of applications by manufacturers in the automotive appliance office furniture lighting and tubing industries. Cold rolled steel yield strength is higher compared to hot rolled steel sheets.
