Problems solved by technology

[0004] The Chinese invention patent with the application number 200610147771.9 discloses a strong and tough ultra-high-strength stainless steel. The stainless steel adopts an optimized composition design, and adopts an enhanced double-vacuum smelting process and a large forging ratio forging forming technology. However, C, Co Lower content and therefore slightly less strength
[0005] The Chinese invention patent with the application number of 200610046063.6 discloses a high-strength, corrosion-resistant and high-temperature-resistant nano-alloy steel material and its production method. By adding Nb to molten steel, W, Mo, V and other elements are added to make the alloy steel 80 % grain size is less than 50 nanometers, the material composition used in this invention can meet the demand of high strength, but the production method of this invention is only through simple smelting to obtain high-strength corrosion-resistant and high-temperature resistant nano-alloy steel material, the obtained material strength is not high , and poor toughness
[0006] Most of the high-strength stainless steel materials in the prior art are only improved from one aspect, that is, from the material composition or the preparation method. Since the preparation method of the stainless steel material has a great influence on the comprehensive performance of the stainless steel material like its chemical composition, there is It is necessary to develop a high-strength stainless steel material that meets the high-strength requirements in terms of material composition and can exert the best performance of the material in terms of preparation methods to obtain a high-strength stainless steel material with excellent comprehensive properties
