GB/T1591-2018 Q355NB is a low-alloy high-strength structural steel. This steel has high strength, good fatigue resistance; high toughness and low brittle transition temperature; good cold forming performance and welding performance; good corrosion performance and certain wear resistance. Steel A514 Gr B high strength steel plate products are delivered in hot rolled, normalized, normalized rolled or thermomechanical rolled (TMCP) state.
Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ～ 0.75, Mn: 0.20 ～ 0.50, P: 0.07 ～ 0.15, S≤0.03, Cu: 0.25 ～ 0.55 , Cr: 0.30 ～ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet A514 Gr B high strength steel plate is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.
The S355 steel material itself is divided into many grades, so it cannot be said that S355 is equivalent to which grade of the national standard Q345, A514 Gr B high strength steel plate. In engineering, usually S355JR steel is equivalent to Q345B steel, S355J0 steel is equivalent to Q345C steel, S355J2 steel is equivalent to Q345D steel, S355N steel is equivalent to Q345D steel, and S355NL steel is equivalent to Q345E steel.
The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries.
