cold rolled steel specification

In this article, Mirach Metallurgy Co.,Limited share different properties between cold rolled steel and hot rolled steel. You can also see cold rolled steel’s detail information below.

Rolling Temperatures

Hot-rolling requires temperatures of 1,652 degrees to 2,012 degrees Fahrenheit (900 to 1,100 degrees Celsius), while cold-rolled steel is rolled at room temperature.

Product Thicknesses

Typically, hot rolling begins with a standard 10-inch (250 mm) thick slab. Cold rolling through a second series of mills further reduces the hot rolled steel to a cold rolled product with a thickness range from .0126 inches (.32 mm) to .157 inches (3.99 mm).
