EN 1.4592 (X2CrMoTi29-4) Stainless Steel
EN 1.4592 stainless steel is a ferritic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 1.4592 is the EN numeric designation for this material. X2CrMoTi29-4 is the EN chemical designation.
It has a moderately low thermal conductivity among wrought ferritic stainless steels. In addition, it has a fairly high tensile strength and a fairly high embodied energy.
The graph bars on the material properties cards below compare EN 1.4592 stainless steel to: wrought ferritic stainless steels (top), all iron alloys (middle), and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.

Alloy Composition
Among wrought stainless steels, the composition of EN 1.4592 stainless steel is notable for containing a comparatively high amount of chromium (Cr) and including titanium (Ti). Chromium is the defining alloying element of stainless steel. Higher chromium content imparts additional corrosion resistance. Titanium is used to broadly improve mechanical properties.
