7mm thickness SM490A carbon steel grades for sale
The main raw material of SM490A carbon steel grades, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of SM490A carbon steel grades, hot rolled steel plate is slightly higher than that of cold rolled steel sheet. In the case of little difference in composition, the density of cold rolled steel sheet and hot rolled steel plate is the same. Hot rolled steel plate has characteristics of low hardness, easy processing and good ductility. Cold rolled steel sheet has high hardness, and it is relatively difficult for processing. But it is not easy to deform and has high strength. Hot rolled steel plate can be made into alloy steel plate by adding other elements, and its properties are also excellent compared with other high-quality steel plates.
ASTM A992 steel SM490A carbon steel grades is recognized as the most suitable steel for wide flange beam in the world. It contains a variety of alloy elements, such as vanadium, niobium, copper, nickel, chromium and molybdenum, which greatly improve SM490A carbon steel grades its strength and other properties. For example, the mechanical properties are much better than the tensile strength 65ksi and yield strength 65ksi of a572-50 and A36. Therefore, A992 wide flange beam (H beam) generally replaces a572-50.
Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and SM490A carbon steel grades resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, SM490A carbon steel grades new materials, and promotes the competition of enterprises Struggle.
