The weldability of A709 grade HPS100W bridge steel plate is good. It means that under certain process and construction conditions, A709 grade HPS100W bridge steel plate can obtain good performance after welding. Weldability is a measure of the hot workability of steel. Weldability can be divided into weldability in construction and weldability in use. Weldability in construction refers to the sensitivity of cracking in weld metal and near seam zone, and hardening sensitivity of steel in near seam zone. Good weldability means that under certain welding process conditions, the weld metal and steel near the seam do not produce cracks. Weldability in use means that the mechanical properties of weld and HAZ steel are not lower than those of base metal.
Recently, the A709 grade HPS100W bridge steel plate price has fallen into a dilemma, and Tangshan production restriction has started again. When the market transaction is weak, the A709 grade HPS100W bridge steel plate price gain support again. Although the high demand is not good at present, which will restrain the rise of A709 grade HPS100W bridge steel plate price, the preference of market mentality and cost side make most A709 grade HPS100W bridge steel plate manufacturers optimistic about the prosperous season. Therefore, it is expected that the A709 grade HPS100W bridge steel plate price will be easy to rise and difficult to fall in the near future, so it is suggested that businesses can make up stocks at low prices.
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 A709 grade HPS100W bridge steel plate 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.
