What is SA573 Grade 70 structural steel mild plate chrome

The company now has SA573 Grade 70 structural steel mild plate oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than SA573 Grade 70 structural steel mild plate 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.

Steel is an alloy of iron with carbon, silicon, manganese, phosphorus, sulfur and a small amount of other elements. In addition to iron, carbon content plays an important role in the mechanical properties of SA573 Grade 70 structural steel mild plate and so on steel. Iron and steel is an important raw material for machinery, construction, hardware and other industries. As an important pillar industry, the development of iron and steel has a glorious period, in which Tangshan was once an important production base of China's iron and steel. This is closely related to its geographical location and energy advantages.

SA573 Grade 70 structural steel mild plate, Q345B low alloy steel has outstanding characteristics, such as:
First, Q345B low alloy steel has good toughness. It is easy to bend and stretch, not easy to break, and can be used for multiple processing. Second, SA573 Grade 70 structural steel mild plate, Q345B low alloy steel is easy to weld and can be used for assembly. Third, Q345B low alloy steel has good strength, good compression resistance and long service life. Fourth, the weather resistance of Q345B low alloy steel is good, and the use is not affected whether it is winter or summer.

The martensite microscopic strength of the wear-resistant layer of the SA573 Grade 70 structural steel mild plate, wear-resistant steel plate can exceed HVl700-2000, and the surface strength can exceed HRC58-62. The key to the wear-resistant layer of the wear-resistant steel plate is dominated by cobalt alloy, and other alloy components such as manganese, molybdenum, niobium, and nickel are added. The martensite in the alloy composition is filled with fibers, and the orientation of chemical fibers is vertical to the surface.

SA573 Grade 70 structural steel mild plate, Q345R pressure vessel steel is an ordinary low alloy steel, which is commonly used for boiler and pressure vessels. The delivery status of Q345R pressure vessel steel is hot rolling or normalizing. The properties of Q345R pressure vessel steel are similar to those of Q345 steel (16Mn). The yield strength of 16mm steel plate is greater than 345 Mpa, the tensile strength is 510-640 Mpa, the elongation is more than 21%, and the zero degree V-shaped impact energy is greater than 34J. The process reference standard of Q345R pressure vessel steel is GB713.
