EN 10025-2 steel includes S235 steel (S235JR, S235J0, S235J2), S275 steel (S275JR, S275J0, S275J2), S355 steel (S355JR, S355J0, S355J2, S355K2), S450 steel (S450J0). According to EN 10025-2, the thickness of S450J0 plate is within 3-150mm. The asme sa588 and sa572 steel exporter, S235 steel, S275 steel and S355 steel plate thickness is ≤250mm. However, the S235J2, S275J2, S355J2 and S355K2 plates limitation is ≤400mm.
The addition of Ca element in steel such as asme sa588 and sa572 steel exporter can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
Novel coronavirus pneumonia has been closed in recent years, and Pohang iron and Steel Co., Ltd. closed its overseas processing center in Italy, Malaysia, Philippines and India. At the request of the Italian government, all production activities will be stopped except for the necessary asme sa588 and sa572 steel exporter products. POSCO-ITPC, an Italian stainless steel cold rolling mill near Verona in northeast Italy, is scheduled to close from March 26 to April 3.
