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 ASTM A210 boiler tube 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.

Material common grades: Q235B, Q345B, AB EH32, AB DH36, AB EH36, ASTM A210 boiler tube, CCS-A, CCS-B, CCSA, CCSB, CCS, CCSD, CCSE. Carbon structural steel plates and sheets are mainly used in the manufacturing of mechanical parts with complex shapes and high requirements for mechanical properties, but it is difficult to shape them by forging and pressing in the process, such as the gearbox shell of the automobile, the coupler and coupling of the locomotive and vehicle.
The company sold 50,000 tons of hot rolled plates to Southeast Asian countries, which will help the construction of relevant ASTM A210 boiler tube key projects in countries along the “Belt and Road”. In response to the local environment and construction needs in Southeast Asia, the company has made a number of improvements to its export products, with excellent cost performance such as low emissions and low fuel consumption. It is an ideal compaction equipment for the ASTM A210 boiler tube construction of high-grade highways, railways, airports, ports and industrial sites. Loved by customers from countries along the “Belt and Road”.
