In recent years, in line with the development trend of iron and A573 Grade 70 rolled structural steel steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which A573 Grade 70 rolled structural steel are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.
Q345 is a steel material. It is a low alloy steel (C < 0.2%), with good comprehensive properties, low temperature properties, cold stamping properties, A573 Grade 70 rolled structural steel welding properties and machinability. Q345 steel is subdivided into Q345A, Q345B, Q345C, Q345D and Q345E. This is the grade distinction, which represents that the impact temperature is different! Q345A, no impact; Q345B, impact at 20 degrees normal temperature; Q345C, impact at 0 degrees; Q345D, impact at - 20 degrees; Q345E, impact at - 40 degrees. At different impact temperature, the impact value is different.
The bridge steel plate is mainly used for erecting railway bridges, highway bridges, sea crossing bridges, etc. The bridge steel plate is required to have high strength and toughness, bear the load and impact of rolling stock, and have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. The bridge steel plate A573 Grade 70 rolled structural steel should also have good welding performance and low notch sensitivity. If you want to have a more comprehensive and detailed understanding of bridge steel plate, welcome to visit our official website for consultation.
Vanadium mainly exists in the form of carbide in A573 Grade 70 rolled structural steel and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.
A573 Grade 70 rolled structural steel, SA36 steel plate is one of our main product, it is belong to the carbon and low alloy high strength steel plate. We can supply the different sizes of SA36 steel plate. And the rolling size of SA36 steel plate is following: the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the SA36 steel coil thickness should not exceed 25 mm.
BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the A573 Grade 70 rolled structural steel hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.
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.
