Effect of P content fluctuation on mechanical properties of 05CuPCrNi grade steel
In today's 05CUPCRNI grade steel steel market, most of the varieties are in excess of demand, especially after China's accession to the WTO, steel enterprises are facing increasingly fierce market competition. In order to make enterprises win a good survival and development space, operators must make effective use of 05CUPCRNI grade steel market information resources to improve the scientificity of business decision-making and enhance the enterprises' domestic competitiveness Competitiveness in the external market.
"Turkey has filed a lawsuit against EU steel import tariffs with the world trade organization, the trade ministry said Friday. In February 2019, the European Union said that the sharp increase of Turkish steel imports 05CUPCRNI grade steel seriously threatened the steel producers in member countries. The European Union has set import quotas for 26 kinds of steel products and imposed a 25% tariff on future steel products for three years.
At the initial stage of corrosion, the rust layer on the surface of weathering steel is denser than that of carbon steel, 05CUPCRNI grade steel, and there are relatively few cracks and holes. After 25 days, delamination occurs in some parts of carbon steel and weathering steel, and there is no difference in corrosion products, mainly due to the role of alloy elements in the rust layer. The precipitation of Cu and Cr alloy elements in the weathering rust layer can resist the invasion of moisture and harmful ions in the atmosphere, and further corrosion of steel and base metal can be prevented, so as to achieve the effect of atmospheric corrosion resistance.
