EN10025-2 S355JR low alloy steel grade is equivalent to GB Q345B in Chinese standard. For the normal thickness, these two steel grades are both owned 345MPa yield strength. Plate S355JR+N indicates that the S355JR steel plate must be done Normalized heat treatment when rolling for improve the steel strength and weldability. Our mill would roll A514 grade E QT steel plate, S355JR alloy steel plate under as rolled or control rolled when customers' have not requested any heat treatment in their P/O.
The company's A514 grade E QT steel plate steel products are sold all over the world with high quality and low price. We can process and cut all kinds of special-shaped parts according to your requirements, or we can set and roll futures of all kinds of material specifications according to your requirements, with fast delivery time. We sincerely welcome new and old customers from all walks of life to contact us for A514 grade E QT steel plate business negotiation. With the enthusiasm, good reputation and professionalism of our staff, we will provide excellent services to our valued customers in all aspects, so as to achieve common development and prosperity.
In actual processing applications, the processing A514 grade E QT steel plate thickness of flame cutting ranges from 6 to 200 mm, and the A514 grade E QT steel plate 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 A514 grade E QT steel plate with a certain thickness above 10mm.
Generally speaking, rolled plates are easier to handle in a high temperature environment, and the heat treatment of A514 grade E QT steel plate, rolled plates is also very common. Hot rolling can not only greatly reduce energy consumption and save costs, but also improve the processing performance of metals and alloys, that is, the coarse grains in the as-cast state are broken, the cracks are healed significantly, and the processing performance of the alloy is improved.
To provide customers with the most satisfactory service and realize the win-win of economic and social benefits, our company promises to provide excellent A514 grade E QT steel plate products in this bidding, and in line with the attitude of being serious and responsible to customers, before sending goods to users, the A514 grade E QT steel plate technical personnel shall confirm that there is no fault in the equipment before sending goods to users, and then send goods and products to users, and formulate the following service terms.
