Ordinary carbon structural steel S275ML steel has many impurities and low price. The ordinary carbon structural steel is used in places with low performance requirements and low strength, but it has good plasticity, toughness and cold deformation performance. High quality carbon structural steel has less harmful impurities, and its strength, plasticity and toughness are better than those of ordinary carbon structural steel. High quality carbon structural steel is mainly used to manufacture important mechanical parts.
EU-28 countries produced 38.29 million mt of S275ML steel, crude steel in the first quarter down by ten percent year on year. In the given period, Germany's output was 9.47 million mt. falling by 9.3 percent year on year. Italy's crude steel output was 5.28 million mt, down by 16.2 percent year on year, and France's crude steel output amounted to 3.73 million mt decreasing by 3.6 percent year on year.
The difference between cold rolled steel sheet and hot rolled steel plate. The carbon content of S275ML steel, 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.
Steel plate is divided into rolling, hot rolling and cold rolling. The width of the thin plate is 500 ~ 1500 mm; the width of the thick plate is 600 ~ 3000 mm. Thin plates are classified according to steel types, including ordinary steel, steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, S275ML steel, bearing steel, etc .; according to use, there are ship plates, pressure vessel plates, atmospheric corrosion-resistant steel plates, bulletproof steel plate.
