The hot rolling process of A573 Gr.70 steel and Q390C steel comparison

Shipbuilding steel plates are used to manufacture the hull of marine and inland ships. High strength, plasticity, toughness, cold bending performance, welding performance and corrosion resistance are required for shipbuilding steel plates. Boiler steel plates are used to manufacture various boilers and important accessories. As the boiler steel plate works under medium temperature (below 350℃) and high pressure, it is also subject to impact, fatigue load and water and gas corrosion. The A573 Gr.70 steel and Q390C steel comparison, boiler steel plate is required to ensure a certain strength and have good welding and cold bending properties.

In actual processing applications, the processing A573 Gr.70 steel and Q390C steel comparison thickness of flame cutting ranges from 6 to 200 mm, and the A573 Gr.70 steel and Q390C 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 Q390C steel comparison with a certain thickness above 10mm.
