420 stainless steel cold rolled strip
① "stainless steel belt / coil" as raw material, at room temperature by cold rolling mill into a material. Conventional thickness <0.1mm ~ 3mm>, width <100mm ~ 2000mm>;
② "cold rolled steel strip / coil" with a smooth surface, smooth, high dimensional accuracy and good mechanical properties, the product mostly roll, can be processed into coated steel;
③ cold-rolled stainless steel with / roll Production process: ⒈ pickling → ⒉ room temperature rolling → ⒊ process lubrication → ⒋ annealing → ⒌ flat → ⒍ fine cut → ⒎ packaging → ⒏ reach the customer hands.
420 stainless steel hot strip
① made by the hot rolling mill thickness 1.80mm-6.00mm, width 50mm-1200mm strip.
② hot-rolled strip / sheet with low hardness, easy processing, excellent ductility and other advantages.
③ hot-rolled stainless steel with / roll Production process: ⒈ pickling → ⒉ high temperature rolling → ⒊ process lubrication → ⒋ annealing → ⒌ flat → ⒍ fine cut → ⒎ packaging → ⒏ reach the customer hands.
Hot and cold distinction
① cold-rolled strip strength, yield ratio is good, hot-rolled strip ductility, good toughness.
② cold-rolled strip thickness of thin, hot rolling thickness.
③ cold rolled steel strip surface quality, appearance, size accuracy are better than hot-rolled plate.
delivery status:
Heat treatment (annealing, normalizing, tempering after tempering, high temperature tempering) state delivery. Strip in the performance meet the requirements of the standard conditions, without heat treatment delivery. Ordinary pull-off strip allows delivery without heat treatment.
Use: Widely used in the automotive industry, aviation industry and other departments, the use of large.
