Q235 Hot Rolled Black Low Carbon Steel Coil

Steel coil, also known as steel coil. It takes slab (mainly continuous casting slab) as raw material, and Q235 ordinary carbon structural steel is also called A3 steel. Q represents the yield limit of this material. The following 235 refers to the yield value of this material, which is about 235mpa. After heating, the strip steel is made by roughing mill and finishing mill. The hot steel strip from the last finishing mill is cooled to the set temperature through laminar flow and rolled into steel coil by coiler. The cooled steel coil is processed into steel plate, flat coil and slitting steel strip products through different finishing operation lines according to the different needs of users. Due to its high strength, good toughness and various steel specifications, steel coil products are also widely used, ranging from general engineering structures to the manufacture of automobiles, bridges, ships, boilers and pressure vessels. For different purposes, the requirements for the mat…
