The steel such as P235GH steel delivered in the hot-rolled state has a certain degree of corrosion resistance due to the high temperature, so it can be stored in the open air. However, this layer of oxide scale also makes the hot-rolled steel surface rough and the size fluctuates greatly. Therefore, the steel with smooth surface, accurate size and good mechanical properties is required to be produced by using hot-rolled semi-finished products or finished products as raw materials and then cold rolling.

p235gh steel and so on steel structure engineering steel has good plasticity, which can make the structure have obvious deformation before being destroyed, so as to avoid brittle failure of structure. The good plasticity of steel can adjust the local peak stress to redistribute the stress, and improve the ductility of components, so as to improve the seismic capacity of the structure. The impact toughness of p235gh steel and so on steel structure engineering steel is good, which can improve the ability of resisting dynamic load and avoid the occurrence of cracks and brittle fracture.

p235gh steel discount steel plate and sheet (size mm) supply: 10*2200*12000, 18*2000*000, 14*2000*12000, 22*2500*1000, 12*2000*11000, 16*2500*10000, 14*2000*11000, 25*2000*10000, 12*2000*12000, 14*2500*10000, 14*2000*10000, 20*2500*10000, 12*1800*10000, 16*2200*000, 14*2000*9000, 22*2200*1000, 12*1800*9000, 16*2000*10,000, 16*1800*10000, 14*1800*9000, 20*2000*10000, 22*2200*10000, 30*2500*10000.

Rare earth has a great affinity for the residual harmful non-metallic elements in steel. It can not only further remove the residual O, S, P and other harmful components in steel, but also change the morphology of sulfide and oxide in steel. While reducing the total number of inclusions in steel, it can also change the large strip sulfide into spherical and fine sulfide, so as to improve the quality, toughness, weldability and corrosion resistance of the steel material, p235gh steel.
