Welcome to BBN High Strength Steels Factory
Our company is China's 10th largest supplier & Exporter of stainless steel, carbon steel plate and section, alloy steel plate and pipes. We are specialized in stocking & distributing various Stainless Steel, carbon steel plates, S460QL1 steel pipe angle steel, H beam steel to worldwide for specific & urgent requirements. We have a fully advanced and modernized warehouse that stores tonnes of our value-adding S460QL1 steel pipe products, which we source out from the mills that are compliant with the universal guidelines for plate production.
For Q345B steel plate, Q stands for the yield of Q345B material. The 345 at the back refers to the yield value of Q345B material, which is about 345MPa. The yield value will decrease with the increase of Q345B steel plate thickness. Q345B steel plate has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability. It S460QL1 steel pipe is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.
Our company's business departments are a group of excellent and hard-working employees, who constantly carry out knowledge updating and steel knowledge training every day, only to provide better and professional services to customers.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of S460QL1 steel pipe, 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.
