Our company's A514 grade Q QT steel plate power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the A514 grade Q QT steel plate utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.
All steel pipes operated by our company are in compliance with national standards, and the original bill of materials of steel mills is attached. At the same time, we supply the A514 grade Q QT steel plate seamless steel pipe, electrical Resistance Weld pipes, large diameter welded pipes ordering business of various specifications and materials and the railway and road transportation business for the majority of users.
There are many advantages of A514 grade Q QT steel plate, pickling coils. The surface of pickling coil is smooth, and the outside is very beautiful. From the appearance, we can see how the manufacturer's technology is, and it is convenient to use pickling coils in engineering. In addition, the cost can be reduced by using pickling coil instead of cold rolled sheet. The corrosion resistance of pickling coil is better than ordinary steel plate, and its service life is also very long.
During cladding welding of hardfacing wear-resistant steel plate, A514 grade Q QT steel plate, preheating and slow cooling should not be adopted. Sometimes, forced cooling measures are even taken to reduce the residence time of weld in the temperature range of 400-850℃ to prevent local chromium deficiency in austenite grain boundary and σ brittle phase in the plate, resulting in 475℃ brittleness, so as to ensure that the weld metal has good mechanical properties and intergranular corrosion resistance.

The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the A514 grade Q QT steel plate, 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.
Our company will accept the product quality objection registration record, pass it to the A514 grade Q QT steel plate production unit and relevant departments, and timely coordinate the supervision of product A514 grade Q QT steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
