Hot-rolled Steel Sheet
Hot-rolled steel sheet is a long strip of steel with a rectangular shape and a thickness that is greater than 6mm after being rolled. According to material, it is divided into ordinary steel, stainless steel and special alloy steel. Hot rolled steel sheet is not limited to a certain length. Commonly hot rolled steel coils are 3-12m long. During the production process, due to its great thickness, it is usually rolled and cooled in several times and then divided into several hot rolled steel sheets; the longitudinal size is usually finished in the hot-rolled condition.
Hot-rolled steel sheet has the advantages of good mechanical properties, continuous and uniform structure, good shock absorption and anti-vibration performance, good compression and anti-cracking performance, good strength and high hardness, wear resistance and heat-resistant fatigue. There are many applications of hot rolled steel sheet in engineering. It is used for manufacturing large tank, tower, bridge, ship, chemical pipeline and pressure vessel components, various machines and their components, such as: walls, bridges, piping and etc.
Due to its good performance, hot rolled steel sheet is very popular. Hot-rolled steel sheet usually refers to the steel sheet with a thickness of more than 6mm and a width of 600mm-2100mm. The production of hot rolled steel sheet conforms to the national standard YB / T002-1991. According to the chemical composition of steel, it can be divided into 5 categories, namely general structural steel, carbon structural steel, low alloy structural steel, mold steel, heat-resistant structural steel. The shape of hot-rolled steel sheet includes: hot-rolled steel sheet in coil, hot-rolled steel sheet cut butterfly, hot-rolled steel sheet shear flat sheet, hot-rolled steel sheet flame cutting sheet, hot-rolled steel sheet mill edge flat sheet and edge trimming sheet, the strip is divided according to width.
In short, hot-rolled steel sheet has the advantages of good foundation strength, adequate plasticity under general engineering structural conditions, easy welding, cutting and welding, and good forming performance. Therefore, hot-rolled steel sheet is widely used in various machinery manufacturing, engineering and construction industries.
