Product description：Hot rolled steel is steel that has been roll-pressed at very high temperatures—over 1,700, which is above the re-crystallization temperature for most steels. This makes the steel easier to form, and resulting in products that are easier to work with. To process hot rolled steel, manufacturers first start with a large, rectangular length of metal, called a billet. The billet is heated and then sent for pre-processing, where it is flattened into a large roll. From there, it is kept at a high temperature and run through a series of rollers to achieve its finished dimensions. Steel shrinks slightly as it cools. Since hot rolled steel is cooled after processing, there is less control over its final shape, making it less suitable for precision applications. Hot rolled steel is often used in applications where minutely specific dimensions aren't crucial.   

Product description：Hot rolled coils use slabs (mainly continuous casting slabs) as raw materials, and after heating, they are processed by rough rolling units.Due to the high strength, good toughness, easy processing, and good weldability of hot rolled steel products, they are widely used in manufacturing industries such as ships, automobiles, bridges, construction, machinery, and pressure vessels.  

Product description： Hot rolled coil is made of continuous casting slab or initial rolling slab as raw material, heated by a stepper heating furnace, descaling by high-pressure water, and then enters the roughing mill. The roughing material is cut into heads, tails, and then enters the finishing mill for computer-controlled rolling. After final rolling, it is cooled by laminar flow (computer-controlled cooling rate) and coiled by a coiler to become straight coil. Steel coil ST37-2 is a grade of hot-rolled steel coil that is commonly used for general purposes such as manufacturing pipes, structures, and machinery. It is a low carbon steel with a minimum yield strength of 235 MPa and a tensile strength ranging from 360 to 510 MPa, making it relatively strong and ductile.  

Product description： Q345 steel specification: Q345 steel belongs to 16Mn steel grade, usually it is produced in hot rolled state, hot rolled steel plate, hot rolled steel coil/sheet, it has comprehensive mechanical and welding property, as it shows good performance in structural purposes, it is widely used as welding structural part in manufacturing of ship, railway and vehicles, bridges, boiler, pressure vessel container, steel oil tank, etc. Yield point of Q345 steel plate decreases as plate thickness increases.  

Product description：Q235 ordinary carbon structural steel is also known as A3 steel. Q represents the yield limit of this material, and 235 behind it means that the yield value of this material is about 235MPa. The yield value will decrease with the increase of the thickness of the material. Due to moderate carbon content, good comprehensive performance, strength, plasticity and welding properties have been better matched, the most widely used.  

Product description： Q195 is a carbon structural steel with a yield strength of 195MPA, which is lower than Q235. The ASTM designation is Gr.B (σs185).
