Why the use of A573gr.65 inspection is more cost-effective

Nowadays, transportation is an important factor in economic development. Our company's rapid development is also inseparable from a good geographical location. The company is located in Zhengzhou, an important A573gr.65 inspection heavy industry area in Central China. Whether you are in Beijing, Shanghai or Guangzhou, you can visit our company very easily. My factory is nearby, convenient transportation and time saving.

Boiler vessel plate: it is used to manufacture various boilers and important accessories. Because the boiler steel plate is in the medium temperature (below 350 ° C) and high pressure state, in addition to bearing high pressure, it is also subject to impact, fatigue load and water and air corrosion. A573gr.65 inspection. It is required to ensure a certain strength and good welding and cold bending performance. It is a special steel plate for pressure vessel, which is widely used in China.

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 A573gr.65 inspection alloy steel A573gr.65 inspection 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.

Z-direction steel refers to thick steel with good tensile resistance in thickness direction. In the application of steel plate, the reason for additional performance requirements on the thickness direction of steel is due to the existence of defects in the thickness direction of steel in the process of casting and rolling. This defect makes the steel prone to lamellar tearing during welding, which reduces or even loses the design bearing capacity of application. The Z-direction performance is required for A573gr.65 inspection and so on steel plate with the tensile force along the plate thickness direction greater than or equal to 40mm.

S355J2G3 is low alloy high strength structural steel, and it is roughly equivalent to GB Q345D.S355J2G3 is a European standard steel with composition of C ≤ 0.20, Si ≤ 0.55, Mn ≤ 1.60, P ≤ 0.035, S ≤ 0.035. The meaning of J2G3 indicates that the delivery state of S355J2G3 steel is normalized, the impact energy at - 20 ℃ is 27J. G3 and G4 indicate the deoxidization mode. A573gr.65 inspection, S355J2G3 steel is semi killed steel, S355J2G4 steel is fully killed steel.
