The word starting with S is carbon steel structural steel, and the 355 that follows means that the minimum yield strength at room temperature is 355Mpa. J2 requires -20°C impact. As for the +N behind it, it means equivalent to normalizing rolling and does not necessarily mean normalizing. It is just a method of naming steel grades in the standard.
S355J2+N steel plate implementation standard: EN10025. Similar grades: S235JR+N S235J0+N S235J2+N S275JR+N S275J0+N S275J2+N S275N S275NL S355JR+N S355J0+N S355J2+N S355K2 S355N+N S355NL
S355J2+N steel plate has excellent tensile strength and impact resistance toughness, and S355J2+N steel plate has good processing performance and welding performance.
S355J2 steel plate has good toughness and welding performance, and is suitable for machinery and equipment manufacturing enterprises such as ships, steel structures, metallurgy, mining, engineering machinery, bridge machinery, power station equipment, lifting and transportation machinery, machinery manufacturing and other projects that bear higher loads.
