According to 09CuPTiRE-B size range traders in some regions, the downstream purchasing sentiment is maintained, the inventory resources are relatively small, and the 09CuPTiRE-B size range traders are more willing to strike a deal; in addition, the domestic steel mills have issued guidance prices recently, and the long-term upward range is large, which has a boosting effect on the market. In addition, there are 09CuPTiRE-B size range production line maintenance at the end of the month, so the supply side is tight. Overall, the short-term forecast for 09CuPTiRE-B size range will fluctuate mainly upwards tomorrow.

Vanadium mainly exists in the form of carbide in 09CuPTiRE-B size range 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%.

Weathering steel plate is a kind of natural weathering steel plate with atmospheric corrosion resistance, characteristic corrosion and oxidation, which has been obtained in many fields. The common basic properties and the state of various weathering steel plates have been well reflected in the construction. At present, 09CuPTiRE-B size range it is mainly used for welding and manufacturing of traffic vehicles, construction machinery, bridges, towers, containers, steel containers and other low alloy structural steel. Features: strong toughness, rust resistance, corrosion resistance, thinning and consumption reduction, energy saving.
