Modified austenitic alloys are based on standard austenitics whose alloy content has been modified to obtain or accentuate a specific property above that obtainable in the original material.
In the main, with austentitics, adjusting the alloy content adjusts the microstructure - eg: the alloy modification can be used to eliminate delta-ferrite, eg: to ensure a fully austenitic microstructure or alternatively to guarantee a specific delta-ferrite content.
Superaustenitics in the term given to austenitic stainless steels whose alloy content greatly exceeds the norm either with respect to one element or a combination of elements.
Normally superaustenitics are ferrite free, designed mainly for proprietary alloys when specific high temperature or corrosion properties are required
