| description | The invention discloses modified austenitic stainless steel excellent in high temperature creep resistance and a manufacturing method. The modified austenitic stainless steel comprises a steel substrate and an infiltrated layer. The infiltrated layer comprises an Fe phase diffusion layer, an Fe-Al compound layer and an Al2O3 film. The thickness of the Fe phase diffusion layer ranges from 40 micrometers to 80 micrometers, and the Fe phase diffusion layer contains Al. The thickness of the Fe-Al compound layer ranges from 50 micrometers to 100 micrometers. The thickness of the Al2O3 film ranges from 10 micrometers to 20 micrometers. The manufacturing method comprises the steps that (1) electrolytic polishing is conducted; (2) aluminizing treatment is conducted, specifically, treatment is conducted at the temperature ranging from 400 DEG C to 600 DEG C and the temperature ranging from 900 DEG C to 1050 DEG C, and furnace cooling is conducted; (3) sand blasting is conducted, specifically, the operation is conducte |
