The nm500 gb standard sheet exports are expected to remain stable
Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. NM500 gb standard sheet, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.
The typical hardness of NM500 steel plate is 500 HBW, so it can withstand severe wear. NM500 steel plate is very suitable for working in strong wear environment, such as high strength ore and corrosive materials. NM550 steel plate is a kind of wear-resistant steel plate with an average hardness of 550 HBW. NM500 gb standard sheet Its toughness is the same as that of NM500 steel plate, and it is used in high wear occasions. When the NM500 steel plate is upgraded to NM550 steel plate, the Brinell hardness is increased by 50 units, and the wear resistance life is prolonged without losing the toughness of the NM500 gb standard sheet steel plate.
Since 2020, the foreign trade industry has been significantly affected by the epidemic. In the first two months of this year, China's NM500 gb standard sheet and so on steel exports totaled 7.811 million tons, down 27% year-on-year, the largest decline since March 2018. In terms of steel foreign trade, China is mainly a steel exporting country, with less steel imports.
