Cold Reduced Steel Sheet

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 reduced steel sheet. To about in. But cold reduced steel is flattened without the application of heat which produces a sheet metal that s very strong smooth and slim. The material thicknesses for such thin walled steel members usually range from 0 0147 in. Cold rolled steel yield strength is higher compared to hot rolled steel sheets.

Jis g3141 cold reduced carbon steel sheets and strip. Cold reduced steel sheet cold reduced steel is so cold because of its production at room temperature. Before becoming a cold rolled product it is effectively hot rolled steel which then under goes further processes. 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.

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. The first process is the cold reduction. Our cold reduction mill services make steel harder and stronger. This process is called work hardening.

Usually steel sheets are manipulated at very high temperatures. 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. However after the cold reduced product is annealed heated to high temperatures it becomes very soft and formable. This japanese industrial standard specifies the cold reduced carbon steel sheets coils and strip hereafter referred to as steel sheet and coil including the cold rolled strip steel steel coils less than 500 mm in width during cold rolling and also the cut lengths there from.

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. Thus the sheet not only becomes thinner but also becomes much harder less ductile and very difficult to form. Sheet quality finish cold rolled steel will have closed thickness profile good surface texture and flatness compared with hot rolled steel. The cold reduction operation induces very high strains work hardening into the sheet.
