en standard P235GH steel, Large diameter spiral steel pipe refers to the relatively large diameter spiral steel pipe, which is generally required to be more than 1000mm. The manufacturing process of large-diameter spiral steel pipe: first, the steel strip is bent into shape, and then welded together to make a large-diameter spiral steel pipe of specified size. After being processed into a pipe, hydrostatic test, bending, flattening and other tests shall be carried out, and the internal steel support of large-diameter spiral steel pipe can be made according to customer requirements.

P355NL2 steel plate executive standard: EN10028-3. en standard p235gh steel, P355NL2 steel plate is special alloy steel for pressure equipment. It has good plasticity, toughness, cold bending property and weldability. P355NL2 steel plate is European standard low temperature vessel plate, which is widely used in petroleum, chemical, power station, boiler and other industries. The size, shape and allowable deviation of P355NL2 steel plate shall meet the requirements of EN10028-1 2007 + A1:2009.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.

The main applications of normalizing are as follows:① For low carbon steel, en standard p235gh steel. The hardness of low carbon steel after normalizing is slightly higher than that after annealing, and the toughness is also better, so normalizing can be used as the pretreatment of cutting.② For medium carbon steel, normalizing can be used as the final heat treatment instead of quenching and tempering treatment, or as the preparation treatment before surface quenching by induction heating.③ Normalizing can be used in tool steel, bearing steel, carburizing steel and so on, which can eliminate or inhibit the formation of network carbide, thus obtaining the good microstructure needed for spheroidizing annealing.④ Normalizing can refine the cast structure and improve the machinability of steel castings.
