Effect of cooling process on microstructure and properties of A573 Gr.70 steel and S690QL steel comparison

In actual processing applications, the processing A573 Gr.70 steel and S690QL steel comparison thickness of flame cutting ranges from 6 to 200 mm, and the A573 Gr.70 steel and S690QL steel comparison cutting thickness can even reach 350 mm by replacing the air pipe and cutting torch nozzle. In order to better improve the cutting quality, the related process parameters will be slightly different when using flame cutting for materials of different thickness. The verticality of the cutting surface processed by the CNC flame cutting machine is generally high, and the slope can be controlled below 2-3°. The characteristic is that flame cutting performs better when cutting A573 Gr.70 steel and S690QL steel comparison with a certain thickness above 10mm.

The surface hardness of NM400 wear-resistant steel plate usually reaches 360-450HB, and the steel has a high mechanical strength. Its mechanical properties are three to five times that of ordinary low alloy steel plate. NM400 wear-resistant steel plate has excellent mechanical properties and good wear resistance, and can adapt to various mining conditions under different working conditions. NM400 steel can significantly improve the wear resistance of mechanical components, improve the service life of machinery, and reduce production costs.

The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the A573 Gr.70 steel and S690QL steel comparison, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.
