For Q345B steel plate, Q stands for the yield of Q345B material. The 345 at the back refers to the yield value of Q345B material, which is about 345MPa. The yield value will decrease with the increase of Q345B steel plate thickness. Q345B steel plate has good comprehensive performance, low temperature performance, cold stamping performance, welding performance and machinability. It SA572Gr.55 structural alloy steel is widely used in bridges, vehicles, ships, buildings, pressure vessels, etc.
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 SA572Gr.55 structural alloy steel 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 SA572Gr.55 structural alloy steel manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
In 2014, we offered 175 ton Cold rolled stainless steel plate to Thailand. The SA572Gr.55 structural alloy steel products are from TISCO. Here is the MTC that we offered to customer. We have our own quality team. Our quality team will inspect every order before shipment for customer. Normally, we will test the chemical composition, thickness, width, and length. Here are some pictures for last inspection.
