After solution treatment, it is an unstable austenite structure with good plastic toughness and processability. After adjustment, the austenite precipitates the carbide composition, and after martensite transformation, most of the structure is transformed into toughness. Better low carbon tempered martensite, this state is the state of use of steel, with good medium temperature mechanical properties. Corrosion resistance is superior to general martensitic stainless steel.
