Special Steel or Alloy Steel Coils-Steel Strips

With heat treatment the steels at about 200 degree centigrade and make the steel surface to form a layer of dense ferroferric oxide film,Its main ingredient is ferro ferric oxide. CR is short for Cold Rolled Carbon Structural Steel Board, is made by Hot rolled carbon structural steel with further cold rolled treatment for there is no oxidized surface when rolled under room temperature, so CR has good quality surface and high dimensional accuracy,also after the annealing treatment, the mechanical and process performance of CR are always better than hot rolled steel board gradually replaces the hot rolled steel board in many fields Our company owns 7 six high single reversing tolling mill producing ranges of thickness is from 0.12 to 1.5mm width is from 900 to 1250mm, can achieve annual capacity 1.68 million tons, the main control

technology involves thickness control system and automatic plate type control system. Main testing equipment involves laser velocimeter X-ray thickness tester,tension tester, contact plate type machine etc. The machines are equipped with segmented cooling system to achieve good version control ability, high dimension precision, and can guarantee the dimension and version request of the high-end products.

Which widely used in various: hardware tools, masonry knives, putty knives, bricklaying knives, trowels, shovels, woodworking band saws, saw blades, hand saws, circular saw blades, various garden saws, rolling gate springs , Refueling machine coil spring steel belt, brick machine steel belt, automobile clutch plate steel belt, clock spring, various steel tape measure, lock making, shoe material, textile, sickle material, standard stamping steel belt, and various Material Blue-painted packing belts, as well as other steel belts used in all walks of life are produced.
