  • Stainless Steels - Harry Bhadeshia

    An alternative is use solutes (such as Nb, Ti, V or Ta) which have a greater affinity for carbon than chromium. These are called stabilisedstainless steels, for example, types 321 (Ti stabilised) and 347 (Nb stabilised) austenitic stainless steels.Titanium cannot in general be used to make alloys deposited by arc welding because it readily oxidises; type 347 is used instead as a filler metal.

  • Schaeffler Diagram - an overview | ScienceDirect Topics

    As the stabilizing effect of each element for a given phase is known, it is possible to make use of simple diagrams like the Schaeffler diagram to predict which phase is the stable phase for a given composition of stainless steel (Pickering 1976, Schneider 1960).The Schaeffler diagram (see Fig. 5.1) is prepared by establishing the stable phase (at room temperature) for different compositions ...
