EN steel grade S275J2 plates carbon steel hr plates 2020.10.26

In today's EN steel grade S275J2 plates steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of EN steel grade S275J2 plates market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.

Gas cylinder steel plate is used to manufacture the material which can be used repeatedly to manufacture liquefied petroleum gas cylinders with working temperature of 40-60 ℃, EN steel grade S275J2 plates test pressure of 2.36 MPa, water volume of 23.5L, 35.5L, 118L.

EN steel grade S275J2 plates, 09CrCuSb steel has the following advantages: 1. The alloy ratio is optimized and rare alloy is added. The finished steel product has excellent sulfuric acid uniform corrosion resistance. 2. The content of As, Sn, Pb and other elements, and the gas content of hydrogen, oxygen and nitrogen are controlled to improve the purity of the billet. According to the analysis of many times, the grain size of the material is not coarser than grade 6. The corrosion resistance of the equipment made of 09CrCuSb steel is improved, and the maintenance cycle is relatively prolonged, which has great economic benefits.

If the chromium content in EN steel grade S275J2 plates alloy steel reaches about 12%, dense chromium oxides will be formed on the surface of the steel, which will greatly improve the corrosion resistance of steel in oxidizing media. Chromium, aluminum, silicon and other elements can improve the oxidation resistance of steel and the corrosion resistance of high-temperature gas, but excessive aluminum and silicon will deteriorate the thermoplasticity of steel.
