What are the properties of 09CuPCrNi-A steel and 05CuPCrNi steel

High weather resistance structural steel Q295GNH, Q355GNH adds a small amount of alloying elements such as Cu, P, Cr, Ni, etc. to form a protective layer on the basic surface of the metal to improve the steel with atmospheric corrosion resistance. High weather resistance structural steel is mainly used in the structure of vehicles, containers, buildings, towers or other structural parts. Compared with welded structural steel 09CuPCrNi-A steel hardness, it has better atmospheric corrosion resistance.

Hot rolled 09CuPCrNi-A steel hardness steel coil and plates are among our main products. Hot rolling can significantly reduce energy consumption and cost. During hot rolling, the metal has high plasticity and low deformation resistance, which greatly reduces the energy consumption of metal deformation. Hot rolling can improve the 09CuPCrNi-A steel hardness processing properties of metals and alloys, that is, the coarse grains in the casting state are broken, cracks are obviously healed, casting defects are reduced or eliminated, the as cast structure is transformed into deformed structure, and the processing properties of alloys are improved.

How to distinguish the inferior steel plate? 1. The surface of the fake and inferior steel plate is easy to produce scab. 2. The material of fake and inferior steel plate is not uniform and there are many impurities. The surface of fake and inferior steel plate is often pitted. Pitting is an irregular and uneven defect on the surface of 09CuPCrNi-A steel hardness, steel plate caused by serious wear of rolling groove. Due to the pursuit of profit by the manufacturers of fake and inferior steel plates, the groove rolling often exceeds the standard.

Since the beginning of this year, the global 09CuPCrNi-A steel hardness steel pipe industry, like many other industries, is facing severe market situation. The difference is that novel coronavirus pneumonia is not only affected by the epidemic, but also closely linked to the oil and gas industry, and the global 09CuPCrNi-A steel hardness steel tube industry will also suffer from the "flash collapse" of international oil prices in March.
