SM520C carbon steel plate sheet property of yield strength

The development SM520C carbon steel plate sheet of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with SM520C carbon steel plate sheet high-quality and efficient services, work together for win-win, and create a better tomorrow!

We also produce various sizes of section steel, the main production methods are hot rolling, cold rolling, extrusion, forging, cold drawing and so on. Profile products have complex cross-section shape and various specifications. According to the section height, it can be divided into large section steel, SM520C carbon steel plate sheet, medium and small section steel, H section steel, I section steel (I-section steel), U section steel (channel steel), l section steel (angle steel) and ball flat steel, etc. Profiles are widely used in various sectors of the national economy, such as I-beam is mainly used in building components, bridge manufacturing, ship manufacturing, etc.; channel steel is mainly used in building structures, vehicle manufacturing, etc;

The yield point of the steel structure determines the stress that the structure can withstand without permanent deformation. The minimum yield point of typical carbon structural steel is 235MPa. The minimum yield point of typical low-alloy high-strength steel is 345MPa. Therefore, according to the proportional relationship of its yield point, the use of low-alloy high-strength steel allows the stress to be 1.4 times higher than that of carbon structural steel. Compared with SM520C carbon steel plate sheet, carbon structural steel, the use of low-alloy high-strength steel can reduce the size of structural parts and reduce weight.
