Measures to improve welding performance of steel sheet s235

Vanadium mainly exists in the form of carbide in steel sheet s235 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%.

Our company's logistics breaks through the perspective that the center of transportation service is ability, and emphasizes that the purpose of transportation service is customer first. Customer demand determines the content and mode of transportation service, while production is often small batch, diversified and consumer demand tends to be diversified. In the case of personalization, our logistics service also provides personalized service projects.

The size of the crystal grains can be controlled by the annealing conditions of the steel sheet s235 steel sheet, and the boiling steel sheet is more likely to change greatly. Especially in order to improve the formability of boiling steel sheet s235 steel and the processability of enamel products (such as not easy to foam), it is decarburized and annealed to make cold-rolled steel sheets with coarser grains and soft texture. However, if the crystal grains are too coarse, the forming limit of spinning may be reduced.

steel sheet s235, JIS 3101 SS540 is high strength low alloy steel plate sheet, which is widely used in plants building, general mansions and all kinds of construction machinery, such as mines and various types of drilling rig used in construction, power shovel, electric wheel dump trucks, mining vehicles, excavators, loaders, bulldozers , various types of cranes, hydraulic support, coal mining machinery and equipment and other structures.
