The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the A709 grade 100W bridge steel plate, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.

Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld A709 grade 100W bridge steel plate steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for A709 grade 100W bridge steel plate manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
In February, affected by the new crown epidemic, steel market demand was delayed and steel prices continued to fall. Since March, with the effective control of the new crown epidemic, the downstream industries have resumed production, the market situation has gradually improved, and A709 grade 100W bridge steel plate and so on steel prices are expected to stop falling and stabilize.
