S355J2 is a low-alloy high-strength steel, which can be treated to meet the requirements of Z-15, Z-25, Z-35 and level I, level II and level III flaw detection.The extension grades of S355J2 are S355J2, S355J2-Z35 and S355J2 + N-Z35, A709 Gr 50 high strength steel. On the basis of S355J2, S355J2-Z35 increases the requirement of S355J2 steel plate thickness direction performance, namely Z-direction performance. S355J2 + N-Z35 is a heat treatment process which increases Z-direction properties and normalizing rolling (or normalizing).
The A709 Gr 50 high strength steel processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the A709 Gr 50 high strength steel steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while A709 Gr 50 high strength steel steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of A709 Gr 50 high strength steel steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
