Made from stainless steel strip or stainless steel coil, rolled in a cold rolling mill at room temperature. The conventional thickness is 0.1mm to 3mm and the width is 100mm to 2000mm.
Cold rolled stainless steel strip has many advantages such as smooth and flat surface, high dimensional accuracy and good mechanical properties, and can be rolled or processed into coated steel sheets. Its production process sequence is pickling, room temperature rolling, process lubrication, annealing, levelling, fine cutting, packaging.
Hot rolled stainless steel strip is produced by a hot rolling mill with a thickness of 1.80mm-6.00mm and a width of 50mm-1200mm. Hot rolled stainless steel strip has many advantages such as low hardness, easy processing and good ductility. The production process is in order of pickling, high temperature rolling, process lubrication, annealing, levelling, fine cutting and packaging.
There are three main differences between cold-rolled stainless steel strip and hot-rolled stainless steel strip.Firstly, cold rolled stainless steel strip has better strength and yield, and hot rolled stainless steel strip has better ductility and toughness.Secondly, cold rolled stainless steel strip is ultra-thin and hot rolled stainless steel strip is a little thicker.In addition, the surface quality, appearance and dimensional accuracy of cold-rolled stainless steel strip is better than that of hot-rolled stainless steel strip.
