| description | The invention discloses high-chromium martensitic stainless steel and a production and manufacturing method thereof, and the main idea of the invention is as follows: alloy component optimization design is carried out on the basis of conventional Cr13 and Cr17 stainless steel materials, austenitizing is controlled from the component source, and after the materials are cooled to room temperature, the strength, hardness, plasticity and toughness of the materials are improved; by adding alloy elements and effectively matching the alloy elements, the plasticity, toughness and corrosion resistance of the material are improved by adopting a comprehensive alloying scheme. A special smelting and continuous casting production process is developed according to the components, temperature and solidification characteristics of molten steel, the high-chromium martensitic stainless steel is developed, and the high-chromium martensitic stainless steel has good plasticity, toughness and corrosion resistance through material |
