GB standard wear resistant steel plates parameters: The standard for Chinese wear plates is GB/T 24186, which includes NM400, NM450, NM500, NM550, NM600 etc. steel grades. According to the standard, the NM400 plate thickness is no more than 80mm, and hardness is 370-430HBW. BP300 bulletproof property, NM450 plate thickness is no more than 80mm, and hardness is 420-480HBW. NM500 plate thickness is no more than 70mm, and hardness is 470HBW min. And NM600 plate thickness is no more than 60mm, and hardness is 570HBW min.

When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, BP300 bulletproof property, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.

By Region: data shows that in the first quarter of Asia, crude steel BP300 bulletproof property production was 315.2 million tons, down 0.3% year on year. Crude steel production in the EU region in the first quarter was 38.3 million tons, down 10.0% year on year. The output of crude steel in North America in the first quarter was 29.5 million tons, down 4.0% year on year. According to the output ranking, according to the latest data of the BP300 bulletproof property world iron and Steel Association, the output of crude steel in the top ten countries in March 2020 was 126 million tons (85.71% of the world), and the output of crude steel in the first quarter was 376 million tons (85.07% of the world).

Industry experts point out that employment in the steel industry will almost certainly continue to decline as a consequence of automation, even if production and profits increase. As the conservative think BP300 bulletproof property tank AEI points out, “Mr. Trump’s tariffs are trying to revive a world of steel production that no longer exists. He is taxing BP300 bulletproof property steel-consuming industries that employ 6.5 million and have the potential to grow more jobs to help a declining industry that employs only 140,000.”
