Cold rolled steel
Overview
Cold rolled steel is a type of steel that passes through a rolling mill below its recrystallization temperature of 400-700 ℃. Recrystallization of steel is a microstructural phenomenon achieved through heating. On the other hand, twisted grains are replaced by a new combination of grains, which form and expand until the parent grain is completely transformed; Hot rolled steel can be transformed into cold rolled steel after a series of processing and cooling at room temperature. Cold rolled steel coils have excellent strength and bright surfaces, which increase their aesthetics. In addition, they can also be directly used to produce finished products. Cold rolled steel coil is a widely used product that has been widely used in various industries. As a supplier of cold rolled steel coils in China, Cumic is committed to providing customers with high-quality products.
Product characteristics
Excellent dimensional tolerance and surface finish.
Aesthetics make it an ideal choice for manufacturing products that attract consumers' attention.
After cold rolling, the mechanical properties such as hardness, tensile strength, and yield strength of the steel have been improved and more consistent.
Due to strain hardening, the strength of steel can be increased by 20%.
Steel manufacturers can achieve a lower thickness range than hot-rolled steel coils.
