Good Quality Q235 Zero Spangle Cold Rolled Steel Sheet

Advantages of cold rolled sheet

1. Better surface properties: Parts made of cold-rolled steel usually have a smooth and shiny surface without scale or rust. Therefore, make them useful when aesthetics are essential.

2. Strong processing adaptability ‌ : the elongation after annealing can reach 30%-45%, suitable for complex forming processes such as deep drawing and bending. Surface treatment technologies (such as galvanizing and coating) can expand the corrosion resistance of the material.

3. Outstanding surface quality ‌ : high surface finish without obvious iron oxide scale, can be directly used for finished product manufacturing without secondary surface treatment. After pickling to remove the hot-rolled oxide layer, rolling is carried out to form a uniform and fine metal surface. ‌ ‌

4. Strengthening mechanical properties ‌ : The cold work hardening effect increases the yield strength by approximately 30% to 50%, with a typical value of 300 to 550MPa. ‌ ‌

5.Wide application: Cold plates are widely used in the cooling of electronic devices, battery cooling (especially in electric vehicle applications), data center cooling, laser or medical equipment cooling, and industrial fields.
