What are the latest nm400 weathering steel prices

NM400 weathering steel, High-strength wear-resistant plates have outstanding performance advantages. First of all, the high-strength wear-resistant plates get their name because their wear resistance is very good, and the degree of wear will not be prominent. Secondly, the corrosion resistance of the high-strength wear-resistant plate is very good. General chemical plants have many corrosive liquids, and the high-strength wear-resistant plates can be used as the floor to reduce risk of accidents.

There is no weld on the outer surface of seamless steel pipe, which is the change from round steel progressive perforation to hollow round bar, with good compression resistance. According to different materials, the processed finished products NM400 weathering steel are applicable to a wide range of fields (for example: machine gearbox gears, gear wheel axles, cams, worms, piston pins, claw clutches, high-pressure pipes and various fasteners, high-grade carburized parts, such as gears, shafts, etc.) in the medium containing nitrogen hydrogen mixture for fluid transmission. It can improve the utilization of materials.

Welded steel pipes are made by crimping steel plates, bending them into a circle, and then welding the joints together. Seamless steel pipe is directly processed by round steel piercing or hot rolling process, so there is no weld on the outer surface. The performance of seamless steel pipe is better than that of welded steel pipe, and the price of seamless steel pipe is also higher. There are some differences in chemical composition between NM400 weathering steel, welded steel pipe and seamless steel pipe. The material of welded steel pipe contains the chemical composition suitable for welding.

According to a statistical study, Iran has decided to produce 33 million tons of steel in its calendar year (from March 20, 2020). A study of the performance of the mining sector affiliated to the mining and mining development and transformation organization of Iran (imidro) in the first month of the year (March 20 to April 20) shows that this month produced 5.4% of the 33 million tons produced at the end of this year. In the first month of this year, relevant enterprises in the country produced about 1797927 tons of steel, including NM400 weathering steel, an increase of 1% over the same period last year.
