Carbon structural steel refers to the kind of steel which is mainly used in construction and engineering structures without adding alloy elements. Among all kinds of steel, BV grade B barge carrier steel, carbon structural steel has a large output, the most extensive use and low price. Carbon structural steel is often rolled into various steel bars (round steel, square steel, flat steel, hexagonal angle steel, etc.), section steel (I-beam, angle steel, channel steel, L-shaped steel, etc.), profiled steel and steel plate. Carbon structural steel is mainly used in buildings and engineering structures such as workshops, bridges, ships, etc. Generally, heat treatment is not required for carbon structural steel.
Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, BV grade B barge carrier steel are strict. In the chemical composition of boiler steel, BV grade B barge carrier steel, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
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 BV grade B barge carrier 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.
The alloy steel plate is among our business scope, and it is one of our main product. If you have any demands or questions about alloy steel plate, such as 34CrMo4 BV grade B barge carrier steel material properties, 42CrMo4 AISI equivalent, 12Cr1MoV equivalent ASTM, 40Cr material specification, 42CrMo hardness, 50CrMo4 chemical composition and so on, please free free to communicate with us. We have professional technical team and sales team, who will give you BV grade B barge carrier steel professional answers and quotation about alloy steel plate in time.
The company attaches great importance to the cultivation of team spirit. Personal strength is weak. After sales service departments, leaders and subordinates often communicate with each other. Everyone often holds meetings to discuss their problems in after-sales service, discuss technical difficulties, discuss how to improve work efficiency, how to better deal with user complaints, etc.
