Characteristics and differences between hot rolled stainless steel coil and cold rolled stainless steel coil

Hot rolled stainless steel coils are steels that have been heated and rolled at high temperatures. Hot rolled steel is not very strong, but it is good enough for our use. It has good plasticity and weldability.
Cold rolled stainless steel coil is a steel in which No. 1 hot rolled steel is further thinned to a target thickness by cold working such as cold drawing, cold bending, and cold drawing under normal temperature conditions. It has high strength, but poor toughness and weldability, and is relatively hard and brittle. The maximum thickness of cold rolling is below 0.1--8.0MM.

The difference between hot rolled stainless steel coil and cold rolled stainless steel coil:

Cold-rolled steel sheets are more precise in thickness, smooth and beautiful in surface, and have various superior mechanical properties, especially in terms of processability. However, because the cold-rolled raw coil is relatively brittle and hard, it is not suitable for processing, so the cold-rolled steel plate is usually required to be annealed, pickled and surface smoothed before being delivered to the customer.
