What is the difference between strip steel and round steel? Where are they mainly used?
Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter. Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of which: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. Round bars larger than 25 millimeters are used mainly for making mechanical parts or for seamless steel tubes.Mainly used in the manufacture of various tools, cutting tools, moulds and tools (see tool steel), but also a large number of used in the manufacture of various mechanical parts.
Difference between round bar and other steel bars:(1), is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed, cohesive force that cause steel and concrete, and the bond strength of steel and concrete in the other.(2) the composition is different. Round steel (grade a steel) belongs to ordinary low carbon steel, and most other steel bars are alloy steel.(3), the strength is not the same, low strength steel, and other steel with high strength, the diameter of the same size as compared with other steel, round steel can bear the pulling force than other reinforced small, but the plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in the break before the deformation is much smaller.
Strip steel is a kind of narrow and long steel plate produced by various rolling mills to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. Strip steel, also known as steel strip, is within 1300mm in width, and the length varies slightly according to the size of each roll. The strip is supplied in general, and has the advantages of high dimensional accuracy, good surface quality, easy processing and material saving. Same as steel plate, strip steel is divided into two kinds of ordinary strip steel and high quality strip steel according to the material used, and two kinds of hot-rolled strip steel and cold rolled strip steel according to processing method.Strip steel is widely used in the production of welded steel pipe, made of cold formed steel billet, manufacturing bicycle frame, rim, clamp, gasket, spring, saw blades, hardware and blades.
