Shipbuilding astm a573 structural carbon steel pdf steel plate refers to hot-rolled steel for the manufacture of ship structures produced in accordance with the requirements of the astm a573 structural carbon steel pdf construction society. Often used as a special steel ordering, scheduling, sales, a ship including ship plates, steel and so on.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This astm a573 structural carbon steel pdf alloy steel astm a573 structural carbon steel pdf still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
