How is the red rust on the surface of 09CuPCrNi-A weathering steel plate?

Due to the high corrosion resistance of the 09CuPCrNi-A weathering steel sheet, it takes 1 to 2 years from a new steel plate to a stable, dense rust red protective layer in the natural environment, and may be longer in some dry areas. Even if a simple uniform rust yellow color is to be generated, the 09CuPCrNi-A weathering steel plate takes about one month. In this process, the color of the component will be uncontrollable, from blue black to orange red to rust red, and finally reddish brown. , dramatic, uneven process of change.

Most of the construction landscape projects are tight, and the general public is relatively unfamiliar with the 09CuPCrNi-A weathering steel plate. When they see this process, it is easy to think of the inferior works made with ordinary steel plates (and even the insiders are not easy). Distinguished by the naked eye, this misunderstanding has greatly affected the good design of the building side.

Therefore, katalor introduces a rust-preventing steel plate that accelerates the corrosion of 09CuPCrNi-A weathering steel. The principle is to accelerate the corrosion process of 09CuPCrNi-A weathering steel through a series of physical and chemical processes, so that the workpiece reaches the first order relative within one week of completion. Stable color state, although the color change will occur in the future, but the change is a fairly soft and gradual process, which is quite different from the rust and rust spotting process of the general inferior ordinary steel plate.
09CuPCrNi-A weathering steel sheet is one of the main products of katalor. We have an advantage in providing 09CuPCrNi-A weathering steel sheet. Please contact us if you are interested in the 09CuPCrNi-A weathering steel sheet provided by katalor.
