Why can weather-resistant steel sculpture rust and not rot?

Nowadays, in the garden landscape ecological park, there are also some plastic arts communities that often appear a kind of rust-colored steel raw materials, which shows a design style of industrial production and contemporary art, and its color and layer are very obvious. The cool surface is combined with the surrounding natural environment, showing a kind of industrial production and contemporary formal beauty. This type of raw material is called weathering steel.

Its uniqueness depends on the thickness of a protective layer that is resistant to corrosion over time when exposed to geographical conditions. Do not need to paint maintenance, the service life of raw materials is about 80 years, the surface looks like the weathering steel is very durable, which is the key reason why the weathering steel raw materials are so hot, so why the weathering steel can ensure that the embroider is not rotten, today's sculpture manufacturers will give you a detailed introduction.

The basic principle of corrosion resistance depends on, weathering steel raw material is a carbon steel, weathering steel refers to according to the addition of a small amount of aluminum alloy elements (such as Cu, P, Cr, Ni, Mn, Mo, Al, etc.), so that it has better corrosion resistance than ordinary carbon steel in the air a high alloy steel, its surface in the long-term exposure to produce defensive rust layer, Therefore, the penetration and transport of etched substances can be reasonably blocked.

Its air corrosion resistance can exceed the general carbon steel 2 to 8 times, and the longer the application time, the more prominent its weather resistance effect. Weathering steel also has excellent structural mechanics, electric welding and other characteristics. Because weathering steel can be applied immediately in some natural environments, without surface safety protection such as painting, the development and design of weathering steel types and scientific research on corrosion has been a hot spot in steel research.

Relative to carbon steel, the key reason that weathering steel has excellent air corrosion resistance is that after long-term air exposure, a stable and high-density defensive rust layer is generated on its surface, which blocks the entry of etch substances, so it has the effect of maintenance.
