Q345 is a steel material. It is a low alloy steel (C < 0.2%), with good comprehensive properties, low temperature properties, cold stamping properties, SA573 Grade 65 hot rolled mild steel plate welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
In January 2019, one of our Vietnam customer purchased 395.62 tonsQ345B steel plateSA573 Grade 65 hot rolled mild steel plate for their construction project, we prepared all the goods ready within 5 days, and supplied the goods with painting sand blasting to SA2.5 SA573 Grade 65 hot rolled mild steel plate and priming gray oxide primer, and arrange shipment in time. Meet the customer urgent delivery request.
Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ~ 0.75, Mn: 0.20 ~ 0.50, P: 0.07 ~ 0.15, S≤0.03, Cu: 0.25 ~ 0.55 , Cr: 0.30 ~ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet SA573 Grade 65 hot rolled mild steel plate is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.
Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our SA573 Grade 65 hot rolled mild steel plate products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.
