專利摘要(英)
The present invention discloses a high chromium and silicon-rich corrosion resistant steel, which comprises, in weight percent: 22-30％ Cr, 2-10％ Si, and the balance Fe and incidental impurities, of which a content amount of Cr and Si is less than 37％. Experimental data reveal that, samples of the high chromium and silicon-rich corrosion resistant steel possess specific properties of pitting potential greater than 0.8V and hardness in a range between HV170 and HV500 in the as-homogenized condition. As a result, experimental data have proved that the high chromium and silicon-rich corrosion resistant steel of the present invention can replace conventional stainless steels having poor pitting resistance like type 304 and type 316L, and then be adopted for the applications of components and/or structural parts requiring high corrosion resistance.
