subject: Different Kind Of Steel [print this page] Steel is used in continuous casting, cooling and pressed into flat steel. Plate is a flat, rectangular, by direct rolling or wide strip shear cut.
Steel plate produced according to the method can be divided into the hot rolled steel plate and cold rolled steel. Steel plate according to the surface features can be divided into galvanized steel ( hot galvanized plate, galvanized plate ), tinplate, composite steel sheet and color coated steel plate.
Hot rolled steel sheet means after hot rolling steel plate production. Hot rolled plate has low hardness, easy processing, extensibility features. Because the plastic of hot plate is good, generally for medium plate.
Cold rolled steel is a hot steel plate production. Cold rolled steel has high hardness, processing relatively more difficult, but not easy to deformation, high strength. Cold rolled steel can be used as sheet.
Galvanized steel refers to the surface is plated with a layer of zinc plate. Galvanized steel with corrosion resistant effect, so that the service life is relatively longer, much longer. According to the mode of production, galvanized plate is divided into hot dipped galvanized steel and galvanized sheet.
Tinplate refers to the surface is plated with a thin layer of metal tin plate. Tin plate has good corrosion resistance, has a certain strength and hardness, good forming property and easy welding, tin layer of non-toxic and tasteless, can prevent iron melt into the packaging, and a bright surface, printed pictures can beautify the goods. Mainly used for canned food industry, secondly for the chemical paint, oil, medicine and other packaging materials. Tin plate according to the production process is divided into hot tinplate and tinplate. Statistical tinplate yield according to the weight calculation.
In order to protect the steel from corrosion, can be plating, sticky and spraying method, the surface of the steel plate is covered with a layer of protective" coat", forming a composite steel plate. Galvanized steel sheet, plastic composite plate and belongs to the composite steel plate. Composite plate of many kinds, according to their combination types can be divided into two categories, namely metal composite plate and a metal composite plate.
Color coated steel is cold-rolled steel sheet, galvanized steel, galvanized steel or aluminium zinc plate as the substrate after surface degreasing, phosphating, complexing acid treated, coated with organic coating baked made products.
