Effect of laser welding technology on weld microstructure of weather resistant SA588 grade A steel

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 weather resistant SA588 grade A steel 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.

ASME SA 53 seamless pipe is a low carbon weather resistant SA588 grade A steel steel pipe with carbon content of 0.25% and manganese content of 0.95%. BBN exports all sizes of seamless, black welded and hot-dip galvanized weather resistant SA588 grade A steel steel pipe of ASME SA 53. It is also known as soft steel pipe and is easy to produce.

Our company's technical department is the core department of the whole company. There are a group of very professional technical personnel. They provide some architectural drawings according to the ideas of customers, and they are responsible for how to select the right materials. Including the evaluation of steel products such as multi steel plate, weather resistant SA588 grade A steel and steel pipe, grasp the whole production process, and strictly follow the production standards and customer quality requirements.

From the order to the delivery, there are three quality inspections to ensure that the qualified rate of finished products is more than 100%.
