In the whole steel structure and steel body, the medium and heavy plate is an important part, once the problem occurs, it is easy to fracture, collapse and occur explosion. So how to judge whether the medium and heavy plate, S600MC automobile steel coil is of high quality? First of all, check whether there are cracks on the surface of the S600MC automobile steel coil plate and how glossy it is. Secondly, to measure the thickness error of medium and heavy plate, it is better to use the instrument to measure the bending tensile value. Finally, observe the scale of the steel plate manufacturers, whether there are relevant qualification certificates, and how the production process is.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of S600MC automobile steel coil, 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.
The company will also put Georgetown steelworks on "care and maintenance mode" and temporarily lay off or redeploy about 130 employees working at the steelworks and contractors while some S600MC automobile steel coil maintenance employees will be on staff during the closure. It is stated that unemployment insurance and state-based unemployment support will be available immediately to workers affected by these changes.
