GB/T 4171 Q295GNH weathering steel sheet,ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates are structural quality carbon steel plates just as . ASTM A573 steel gardes are in three tensile strength ranges intended primarily for structural applications at atmospheric temperatures for which improved toughness is required.
GB/T 4171 Q295GNH weathering steel sheet,Q345R steel plate is a special pressure vessel steel with a yield strength of 340 Mpa. GB/T 4171 Q295GNH weathering steel 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,GB/T 4171 Q295GNH weathering steel sheet.
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 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 manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
Difference between Q235A steel and Q235B steel plates: in the national standard GB700, the difference between Q235A steel and Q235B steel plates is mainly in the carbon content. In addition, Q235A steel plate does not do impact test, while Q235B Q235B steel plates need normal temperature impact test, V-notch. Relatively speaking, the mechanical properties of Q235B steel plates are better than that of Q235A steel plate.GB/T 4171 Q295GNH weathering steel sheet
