Abstract: The addition of molybdenum in stainless steel can greatly improve its pitting resistance. However, the addition of molybdenum in medium-high chromium ferritic stainless steel promotes the formation of chromium-rich or molybdenum-rich precipitates in the structure, which can reduce the pitting resistance of the material to a certain extent. So the development of a suitable heat treatment process is an important part of the production of molybdenum-containing ferritic stain¬less steel. This paper takes the 0Crl7Mo2S as an example, the effects of different heat treatment temperature 750 〜1050℃ on the microstructure , mechanical properties and precipitates of the material.Material Index Heat Treatment Process, Mo-Containing Stainless Steel, Metallurgical Structure, Precipitate Phase.
