1.渗铝钢的性能及存在的问题实践证明采用一般碳钢表面渗铝后,可大大提高钢材在高温氧化介质和腐蚀介质中的耐热抗氧化性和耐蚀性(见表1)。从实践中看到,渗铝钢在高温含硫介质中其耐蚀性可与不锈钢相比。因此大力发展和使用渗铝钢材,用渗铝钢代替合金钢,延长碳钢的 1. Aluminized steel performance and existing problems Practice has proved that the use of ordinary carbon steel surface aluminizing, steel can greatly improve the high temperature oxidation medium and corrosive medium heat oxidation resistance and corrosion resistance (see Table 1). From practice, it can be seen that the corrosion resistance of aluminized steel in high temperature sulfur-containing medium can be compared with that of stainless steel. Therefore, the development and use of aluminized steel, aluminized steel instead of alloy steel, to extend the carbon steel
