The invention discloses a preparation method, stainless steel and application of a high-form stainless steel. Ni: 10.0-12.0%, Mo: 2.0-3.0%, N: 0.05-0.09%, S: 0-0.002%, P: 0-0.035%, Ti: 0.1-0.5%, the balance is iron and other unavoidable of impurities, wherein the mass percentages of C, N, Si and Ti satisfy: tensile strength TC=530+540×C%+858×N%+37×Si%+48×Ti%; ≥600MPa. The beneficial effect is that by adjusting the components, the product has higher strength and hardness, so that the stainless steel product has better bulging performance during water swelling molding. |
