Price of 09CuPCrNi-A hardness chart

Medium and heavy plate is widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields. The surface quality of medium and heavy plate mainly refers to its surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plate. The surface quality of 09CuPCrNi-A hardness, medium and heavy plate not only affects the appearance of the products, but also reduces the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate.

ASTM A242 is a kind of high strength low alloy steel with good atmospheric corrosion resistance. Some applications show that it 09CuPCrNi-A hardness has better corrosion resistance than ASTM A36 steel plate and ASTM a572 50 steel plate. Like weathering steel, it can be used without painting, and corrosion naturally stops and becomes a protective layer.

In order to obtain the seamless tube with smaller size and better quality, the method of cold rolling, cold drawing or the combination of the two must be used. Cold rolling is usually carried out on a two high mill, and 09CuPCrNi-A hardness pipes are rolled in a circular pass composed of a variable cross-section circular groove and a fixed conical head. Cold drawing is usually carried out on single chain or double chain cold drawing machines of 0.5-100t.

In February, the European steel price index was 161.2 points, up 1.3 points on a month on month basis, up 0.8%; the euro zone manufacturing PMI was 49.2%, up 1.3 percentage points on a month on month basis. The manufacturing PMI of Germany, Italy, France and Spain were 48%, 48.7%, 49.8% and 50.4% respectively. This month, among the main steel products such as 09CuPCrNi-A hardness in the German market, the price of wire rod decreased slightly, the price of section steel remained stable, and other products continued to rise.
