EN10025-4 S275M steel plate cold formability

The main raw material of EN10025-4 S275M steel plate, hot rolling coil is billet. After heating the billet, the strip made from the coarse and fine rolling mill is cooled to a certain temperature by specific cooling, and then the cooled steel strip is made into rolled steel strip by coiler. But generally, according to the buyer's demand, the manufacturer can further process the cooled steel strip into steel plate or flat coil and other products.

In order to easily and economically perform hot or cold processing to make various parts of engineering structures, the low alloy high strength steel must have appropriate forming properties. Like EN10025-4 S275M steel plate, carbon structural steel, low alloy high strength steel can generally be processed in such way, as well as cutting, punching, and machining. Although the yield point of low alloy high strength steel is high, even if the forming operation is deformed quite severely, cold bending presses, drawing machines, presses and other equipment used for carbon structural steel forming can also be used for low alloy high strength steel, but some equipment needs to be modified.

EU-28 countries produced 38.29 million mt of EN10025-4 S275M steel plate, 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 toughness of steel such as EN10025-4 S275M steel plate is the ability of steel to absorb energy in the process of plastic deformation and fracture, and also the ability of steel to resist impact load. It is related to and different from the plasticity of steel. It is the comprehensive performance of strength and plasticity. The strength plasticity index of steel is obtained by static tensile test. When these indexes are used to bear the dynamic load structure, there are obvious limitations.
