| Abstract: | The microstructure and composition of a high chromium cast stainless steel used in high temperature aqueous alkali with solid grains were designed. The microstructure, corrosion and abrasion behaviours of the new type steel were studied. The results show that the steel has good resistance to abrasion, pitting and intergranular corrosion in the harsh medium of high temperature aqueous alkali with solid grains. In addition, the steel has good comprehensive mechanical and casting properties. |
