Audited Supplier Cold Rolled Steel is steel which has been rolled at room temperature, below its recrystallization temperature. This increases its strength and hardness and decreases its ductility. Cold rolled is then annealed and temper passed to regain grain size and ductility. In addition to improvement of mechanical properties, cold rolling results in more control over the shape and dimensions of the finished product.
Cold-rolled coil (annealed state): It is obtained by bell annealing before rolling. After annealing, the work hardening phenomenon and internal stress are eliminated (greatly reduced), that is, the yield strength is reduced close to that of cold rolling. forward. Cold-rolled coils are made from hot-rolled coils, which are rolled at room temperature below the recrystallization temperature, including plates and coils. Among them, those delivered in sheets are called steel plates, also known as box plates or flat plates; those with long lengths and delivered in coils are called steel strips, also known as coil plates.
cold rolling steel production line adopts the most advanced cold rolling equipments and automatic thickness control system in China. Bright cold rolled steel and black cold rolled steel are available to producing with its surface oil-coated.
