MS sheet metal carbon steel coil SM400A carbon steel plate sheet with boron
Normalizing is a special case of annealing, the effect is similar to annealing, but the microstructure obtained by normalizing is finer. For low or medium carbon steel, normalizing can improve hardness and machinability. For SM400A carbon steel plate sheet medium carbon steel and low alloy steel, normalizing can refine grain and uniform structure and reduce hardness. For high carbon steel and high alloy steel, normalizing can eliminate the network carbide produced by forging and improve the homogeneity of the preparation heat treatment structure.
In particular, the EU imports a large amount of iron ore from central and South America and Oceania, which are mainly transported by sea. The perfect port infrastructure makes the port operation cost of EU iron ore raw materials import relatively low. However, the SM400A carbon steel plate sheet steel transportation between EU Member States is mainly railway transportation, and the EU member states have established a very developed railway network and railway information infrastructure.
S355J2 is a European standard low alloy high strength structural steel grade, equivalent to Q345D. Because of its good impact toughness and welding performance, S355J2 steel plate is widely used in bridges, ships, power plant equipment, hoisting and transportation machinery, machinery manufacturing and other engineering and welding structures that bear high loads. S355J2 steel plate delivery status: hot rolled delivery, the SM400A carbon steel plate sheet specific delivery status should be indicated in the contract.
By Region: data shows that in the first quarter of Asia, crude steel SM400A carbon steel plate sheet production was 315.2 million tons, down 0.3% year on year. Crude steel production in the EU region in the first quarter was 38.3 million tons, down 10.0% year on year. The output of crude steel in North America in the first quarter was 29.5 million tons, down 4.0% year on year.
