Q345B material is a low carbon alloy steel grade with good overall performance, low temperature performance, cold stamping performance, welding performance and machinability. Q345 serues steel is widely used in bridges, vehicles, ships, buildings, pressure vessels. Q represents the yield of this material, and the number 345 refers to the yield value of this material, which is around 345MPa. As the thickness of the material increases, its yield value decreases.

The preparation of a573 grade 58 steel vs a572 grade 55 steel galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for a573 grade 58 steel vs a572 grade 55 steel centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

Good news: In May 17th, 2018, the Myanmar navy's local representative visit our office and hot rolled plate production line, and sign another contract 2025 tons LR A shipbuilding steel plates a573 grade 58 steel vs a572 grade 55 steel order in our office.
