Which has better corrosion resistance, alloy steel 20 or 904
The general test of corrosion resistance of aluminum alloy profiles is salt spray test, or aging test
The main purpose of the test is to judge the test time of different degrees of corrosion of the tested aluminum alloy through the test, in order to analyze the normal service life, the higher the corrosion resistance, the better the mechanical property data, the longer the service life
The characterization data are generally the experimental time, such as salt spray test, which artificially increases the corrosion ability of the environment. The change of the material surface is observed for an average of 12h, and the time before corrosion is summarized. The longer the time is, the
better the corrosion resistance
