In order to further transform the operation mechanism, establish the operation concept of "market-oriented, customer-centric", strive to improve our core competitiveness and promote the rapid development of business; further strengthen customer marketing management, subdivide customer groups, establish a top-down, crisscross, hierarchical marketing mechanism of "everyone is a marketer", and provide for the needs of different levels of customers Corresponding services.
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 S275J0, S275JR, SA36, SS400 carbon structural steel 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.
