ASTM A572 Grade 50, used in large-scale construction, A283 grade D carbon steel plate sheet is an extremely strong alloy with a yield strength of 65,000 psi, an allowable bending stress of 39,000 psi and a future as the high-performance replacement of ASTM A36 steel.

Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. A283 grade D carbon steel plate sheet, Q345R pressure vessel steel has good comprehensive mechanical and technological properties. The content of phosphorus and sulfur of Q345R pressure vessel steel is slightly lower than that of Q345 (16Mn) steel, and the tensile strength and elongation requirements of Q345R pressure vessel steel are higher than those of Q345 (16Mn) steel, and the impact toughness of Q345R pressure vessel steel is also required. Q345R pressure vessel steel is the most widely used Chinese pressure vessel steel.

Q355GNHE corten steel is characterized by adding a small amount of Cu, P, Cr, Ni and other alloying elements to the steel, so that the steel material forms a dense layer between the rust layer and the substrate with a thickness of about 50 to 100 μm and good adhesion to the substrate metal. The amorphous spinel oxide layer prevents oxygen and water in the atmosphere from penetrating into the steel substrate, slows down the rust development to the steel material, A283 grade D carbon steel plate sheet, and greatly improves the steel material's resistance to atmospheric corrosion.

20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel.
