Although corten steel strips were introduced into China late, with the progress of science and technology, corten steel strips technology in China has also been rapidly improved. Corten steel strips have a good development in many fields by virtue of its good corrosion resistance. Corten steel strips are made by adding some elements into ordinary steel strip, so that it has a certain weatherproof. Now let's see what characteristics the corrosion resistance of corten steel strips have.
1. Uniformity of chemical composition: The carbon content in steel is the same as the solubility of carbon in iron to minimize segregation and ensure uniformity of composition. Because low carbon content can reduce segregation trend, the hazard of medium carbon steel is the enrichment of interdendritic alloying elements in peritectic reaction zone.
2. Uniformity of structure: The acicular ferrite is the main structure of corten steel strips by suitable technology. Compared with traditional pearlite and ferrite steels, this kind of structure has better homogeneity, and the electrode potential between micro-regions tends to be more consistent, thus improving its weathering resistance.
3. Suitable chemical composition: The weatherability is guaranteed by the appropriate proportion of weathering elements and the enrichment of rust layer in corten steel strips.
4. Cleanliness and grain size: After vacuum cycle degassing treatment, the whole process of protective pouring, controlling sulfur content, minimizing inclusions, improving the purity of steel, reducing the cleanliness of grain boundary, thereby improving the weatherability of corten steel strips.
Through the introduction above, we have a deeper understanding of the corrosion resistance of corten steel strips. The corrosion resistance of corten steel strips have not only changed its chemical properties, but also improved its cleanliness and grain size. In recent years, corten steel strips also have a good market in container transportation industry.
