Cold rolled strip Hot rolled strip

Cold rolled strip

① “Stainless steel strip / coil” is used as raw material and rolled into cold rolled mill at normal temperature. Conventional thickness <0.1mm ～ 3mm>, width <100mm ～ 2000mm>;

② ["cold rolled steel strip / coil"] has the advantages of smooth and smooth surface, high dimensional accuracy and good mechanical properties. Most of the products are rolled and can be processed into coated steel plates;

③ Cold rolled stainless steel strip / coil production process:

⒈ pickling → ⒉ normal temperature rolling → ⒊ process lubrication → ⒋ annealing → ⒌ flattening → ⒍ fine cutting → ⒎ packaging → ⒏ reach the customer.

Hot rolled strip

① The hot-rolled mill is used to make strip steel with a thickness of 1.80mm-6.00mm and a width of 50mm-1200mm.

② [Hot-rolled strip / sheet] It has the advantages of low hardness, easy processing and good ductility.

③ Production process of hot rolled stainless steel strip / coil:

⒈ pickling → ⒉ high temperature rolling → ⒊ process lubrication → ⒋ annealing → ⒋ smoothing ⒍ ⒍ fine cutting → ⒎ packaging → ⒏ reach the customer.

Hot and cold difference

① Cold rolled steel strip has good strength and yield ratio, and hot rolled steel strip has good ductility and toughness.

② The surface quality, appearance and dimensional accuracy of cold-rolled steel strip are better than those of hot-rolled steel.

③ The thickness of cold-rolled steel strip is ultra-thin, and the thickness of hot-rolled steel is large.
