Strip steel, also known as steel strip, is available in widths up to 1300mm, with lengths varying slightly depending on the size of each coil. However, with economic development, there is no limit to the width. steel Strip is generally supplied in coils, which has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving.
Strip steel in a broad sense refers to all flat steel with a very long length that is delivered in a coil as a delivery state. Strip steel in a narrow sense mainly refers to coils of narrower widths, i.e., what is commonly known as narrow strip and medium to wide strip, sometimes referred to as narrow strip in particular.
The difference between strip steel and steel plate coil
(1) the difference between the two are generally divided into width, the widest strip steel is generally within 1300mm, 1500mm or more is the volume, 355mm or less is called a narrow strip, the above is called a wide band.
(2) plate coil is in the steel plate is not cooled when rolled into a coil, this steel plate in the coil without rebound stress, leveling is more difficult, suitable for processing a smaller area of the product.
Strip steel in the cooling and then rolled into a coil for packaging and transportation, rolled into a coil after the rebound stress, leveling easier, suitable for processing a larger area of the product.
Strip steel grade
Plain strip: Plain strip generally refers to ordinary carbon structural steel, commonly used grades are: Q195, Q215, Q235, Q255, Q275, sometimes low alloy high-strength structural steel can also be categorized into the plain strip, the main grades are Q295, Q345 (Q390, Q420, Q460) and so on.
Superior belt: superior belt varieties, alloy and non-alloy steel species. The main grades are: 08F, 10F, 15F, 08Al, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 15Mn, 20Mn, 25Mn, 30Mn, 35Mn, 40Mn, 45Mn, 50Mn, 60Mn, 65Mn, 70Mn, 40B, 50B, 30 Mn2, 30CrMo, 35 CrMo, 50CrVA, 60Si2Mn (A), T8A, T10A and so on.
Grade and use: Q195-Q345 and other grades of strip steel can be made of welded pipe. 10 # - 40 # strip steel can be made of precision pipe. 45 # - 60 # strip steel can be made of blade, stationery, tape measure, etc. 40Mn, 45Mn, 50Mn, 42B, etc. can be made of chain, chain blade, stationery, knife saws, etc. 65Mn, 60Si2Mn, 60Si2Mn, 60Si2Mn (A), T8A, T10A and so on. 65Mn, 60Si2Mn (A) can be used for springs, saw blades, clutches, leaf plates, tweezers, clockwork, etc. T8A, T10A can be used for saw blades, scalpels, razor blades, other knives, etc.
Strip steel classification
(1) According to the material classification: divided into ordinary strip steel and high-quality strip steel
(2) According to the width classification: divided into narrow strip and medium and wide strip.
(3) According to the processing (rolling) method: hot rolled strip steel and cold rolled strip steel.
