What are the stainless steel stabilizing elements that contain titanium and niobium?

Dear sea friends, what are the stainless steel elements that stabilize titanium and niobium? Please give some advice.
321 contains titanium; it is unknown whether it contains niobium
Just look up the standards by yourself and you’ll know
The reason I mentioned which stainless steels contain stabilizing elements is mainly in relation to a question about measures to prevent intergranular corrosion. One such measure is stabilization treatment. For stainless steels that do not contain stabilizing elements, does stabilization treatment then not work? I checked the standards, and many stainless steels lack such elements, such as S30408.
:Lol, many of the questions nowadays are not well-constructed. . Element constraints are incomplete.
This stabilization treatment is customized with the steel mill at the time of purchasing the steel; it is not specified in existing standards
Materials that contain stabilizing elements (321 contains Ti, 347 contains Nb) can certainly be subjected to stabilization treatment, but there is no standard that mandates this type of heat treatment; it is usually specified by the design. Those without stabilizing elements can undergo solution heat treatment, which can also achieve a stabilizing effect
In the previous version, under item 150, the supply status 321 indicated stabilization
