Normalizing process of S355J2 steel plate: normalize the S355J2 steel plate in the bottom furnace, normalizing temperature is 880-910℃, holding time is 1.8-2.2min/mm, that is to get the required S355J2 + N steel plate. 355j2 + N steel plate is mainly used in large machinery manufacturing, equipment base, large welded steel structure, construction, bridge and other fields. With the continuous development of economy and the large-scale demand of equipment, the demand of ultra thick plate JIS G3125 SPA-H, S355J2 + N steel plate is increasing gradually.
What are the general uses of plate JIS G3125 SPA-H, low alloy steel plate? First, low alloy steel plate can be used as bridge steel plate, because it has strong bearing capacity. The bridge’s daily traffic flow is very large, so it must have very good bearing capacity. Second, because low alloy steel plate has good toughness and is easy to process, it is often used to manufacture ships and vehicles. Thirdly, the use of low alloy steel plate is indispensable to the construction of some frame structure workshops. Because of the low alloy content, low alloy steel plate has its own characteristics.
For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In plate JIS G3125 SPA-H, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.
