Supply heavy nm400 steel equivalent performance

NM400 steel equivalent, Medium and heavy steel plate is a kind of steel plate with outstanding characteristics. First of all, there are many kinds of thickness of medium and heavy steel plate, which are generally relatively thick. Secondly, the thickness of medium and heavy steel plate is relatively thick, so it can be used for high strength application such as bridges. Thirdly, the corrosion resistance and wear resistance of medium and heavy steel plate are much better than ordinary steel plate.

The predecessor of Ningbo port is Ningbo Port Authority. Ningbo port consists of Beilun port, Zhenhai port, Ningbo port, Daxie port and Chuanshan port. It is a multi-functional and comprehensive modern deep-water port integrating inland river port, estuary port and seaport.

Good impact resistance. Wear resistant composite steel plate uses low carbon steel or low alloy, stainless steel and other toughness as the base material. The NM400 steel equivalent metal material not only has good wear resistance, but also can withstand the impact and wear of falling from high to low in the transportation process. It has good heat resistance. Vanadium, molybdenum and other NM400 steel equivalent alloy materials are added into the alloy wear-resistant layer during the manufacturing process, so it can be used and worn at high temperature ≤ 800 ℃. Compared with ordinary NM400 steel equivalent carbon steel substrate, it can only be used below 380 ℃, while low alloy heat-resistant steel plate can work below 540 ℃. This shows how high the heat resistance coefficient of wear-resistant steel plate is. Good corrosion resistance.

According to the data released by the world iron and Steel Association, the world pig iron production in March 2020 was 103 million tons, a year-on-year decrease of 3.5%, a year-on-year increase of 1.8% in February, and the overseas pig iron NM400 steel equivalent production excluding China was 36.309 million tons, a year-on-year decrease of 11%.
