Manufacturing Process
Cold rolled coils are manufactured by reducing hot rolled coils at room temperature through a series of rolling mills. The process enhances dimensional precision and surface smoothness. The coils are then annealed, pickled, and surface treated to meet various industrial standards. Final processing may include slitting, trimming, and edge conditioning.
FAQ
Q: What is the difference between cold rolled and hot rolled stainless steel coils?
A: Cold rolled coils offer better surface finish, tighter dimensional tolerances, and improved mechanical properties compared to hot rolled coils.
