A515 Gr.60, A573 Grade 65 steel carbon plate what is the welding process?

The company specializes in the research and development, production and sales of A515 Gr.60, A573 Grade 65 steel carbon plate seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has A515 Gr.60, A573 Grade 65 steel carbon plate five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,A515 Gr.60, A573 Grade 65 steel carbon plate rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

09CuPCrNi-A is a high-strength weathering steel. Among them, the combination of Cu and P can resist atmospheric corrosion. In addition, there are Cr and Ni, both of which are used in stainless steel. Weathering steel (that is, atmospheric corrosion resistant steel) is a series of low-alloy steels between ordinary steel and stainless steel at a low price and good quality. After incorporating modern metallurgical new mechanisms, new technologies and new processes, it can achieve sustainable development and innovation.

What is the specific use of A515 Gr.60, A573 Grade 65 steel carbon plate, hot rolled plate in daily life? First of all, hot rolled plate is used in bridge, vehicle structure, frame and other fields to play a role of bearing pressure. Secondly, high pressure boiler vessels are also made of hot rolled plates, which can be heat-resistant and airtight, and can stably seal the hot gas in the container. Thirdly, stainless steel hot rolled plate can be used to process hardware products. It has excellent corrosion resistance, and is easy for processing.

A515 Gr.60, A573 Grade 65 steel carbon plate, Hardened wear-resistant plates are gradually annealed at a temperature higher than 250℃ to lose their hardness, which greatly reduces the wear resistance. The welding process will also reduce the hardness near the weld; the wear layer of the bimetal wear plate is of high alloy composition, and there is a secondary hardening effect at a certain temperature, and it can generally work below 650℃.

The proportion of main elements in Q345 steel is basically the same as that in 16Mn steel, the difference is that V, Ti, Nb microalloy elements are added. A small amount of V, Ti, Nb alloy elements can refine the grains, greatly improve the toughness of the steel, and greatly improve the comprehensive mechanical properties of the steel. Because of this, the thickness of A515 Gr.60, A573 Grade 65 steel carbon plate, Q345 steel plate can be made larger. Therefore, the comprehensive mechanical properties of Q345 steel should be better than that of 16Mn steel, especially its low temperature properties. The allowable stress of Q345 steel is slightly higher than that of 16Mn steel.
