40CrNiMoA alloy steel materialGrade 40CrNiMoA Standard: GB/T 3077-2015Advantages: hardenability and stability against overheatingApplication: shafts, gears, fasteners, etc.Raw materials: carbon, silicon, manganese, etc.

Steel plates for high-rise buildings have the properties of easy welding, earthquake resistance, and low-temperature impact resistance, and are mainly used in large-scale projects such as high-rise buildings, super-tall buildings, large-span stadiums, airports, exhibition centers, and steel structure workshops. Compared with ordinary Q235B / Q345B steel plates, these plates KD40 hot rolled steel plate for high-rise buildings have upper limits on yield strength and improved tensile strength, and have requirements for carbon equivalent and yield ratio indexes.

After extrusion, the KD40 hot rolled steel plate tube shall be removed for sizing. The sizing machine uses a cone-shaped bit to rotate into the steel embryo at high speed to drill holes to form steel pipes. The inner diameter of the steel pipe is determined by the outer diameter length of the drill bit of the sizing machine. After sizing, the steel pipe will enter the cooling tower and be cooled by water spray. After cooling, the steel pipe will be straightened. After straightening, the steel pipe is sent to the metal flaw detector (or hydraulic test) by the conveyor belt for internal flaw detection.

How much is plate KD40 hot rolled steel plate per ton? FOB Shanghai: 635$/ton q345qd steel is steel for highway bridges, which is a thick steel plate specially used for erecting railway lines or road and highway bridges. It is required to have high compressive strength, ductility and bearing the load and impact of railway vehicles, as well as excellent fatigue relief, certain ultra-low temperature ductility and air corrosion resistance.

Our company has been established for 20 years and has accumulated rich experience in steel products. At the same time, it is often exported to Southeast Asia, Africa, South America and other countries. So you can rest assured that our KD40 hot rolled steel plate products and our prices are very favorable. Because we have our own factory, there is no other cost, we can also carry out machining and so on.

First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers".
