09CuPCrNi-A stel tensile strength grade mechanical properties chemical composition

Weathering steel has good resistance to atmospheric corrosion. Although the initial investment cost of weathering steel is slightly higher than that of ordinary carbon steel. Compared with methods such as spraying anticorrosive coating on the surface of ordinary carbon steel, the later maintenance costs of ordinary carbon steel are weathering steel. 1.5-2 times. Therefore, 09CuPCrNi-A stel tensile strength weathering steel can reduce environmental pollution and is a key promotion technology for energy saving and emission reduction. Most domestic weathering steels are painted and used, and their original intentions of no-painting and "rust prevention" have not been exerted to a greater extent.

The quality of 09CuPCrNi-A stel tensile strength shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of 09CuPCrNi-A stel tensile strength buyer, such as packaging, delivery time, etc.. On the basis of the quality of 09CuPCrNi-A stel tensile strength in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements.

In February, the North American steel price index was 171.2 points, up 4.6 points on a month on month basis, up 2.8%; the U.S. manufacturing PMI was 50.1%, down 0.8 percentage points on a month on month basis. Among them, the production index decreased by 4.0 percentage points, and the inventory index decreased by 2.3 percentage points; at the end of February, the utilization rate of crude steel production capacity in the United States was 82.5%, 0.2 percentage points higher than that in the previous month. This month, the ex factory prices of major steel products such as 09CuPCrNi-A stel tensile strength in the Midwest steel works of the United States rebounded. Except for the steel prices remained stable, the prices of other steel products rose.

According to the latest statistics of alacero, the consumption of finished steel 09CuPCrNi-A stel tensile strength products in Latin America in 2019 was 64.2 million tons, down 5% from 67.6 million tons in 2018. The decline in steel consumption in the region reflects the economic contraction of Latin American countries, especially the three major economies: Mexico, Argentina and Brazil.
