EN 1.4613 (X2CrTi24) Stainless Steel

EN 1.4613 stainless steel is a ferritic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 1.4613 is the EN numeric designation for this material. X2CrTi24 is the EN chemical designation.

It has a moderately low electrical conductivity and a moderately low thermal conductivity among wrought ferritic stainless steels.

The graph bars on the material properties cards below compare EN 1.4613 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 1.4613 stainless steel is notable for including aluminum (Al) and containing a comparatively high amount of chromium (Cr). Aluminum is used to improve oxidation resistance. It can also enhance the effects of heat treatment. Chromium is the defining alloying element of stainless steel. Higher chromium content imparts additional corrosion resistance.

Iron (Fe) 70.3 to 77.8
Chromium (Cr) 22 to 25
Titanium (Ti) 0.2 to 1.0
Manganese (Mn) 0 to 1.0
Silicon (Si) 0 to 1.0
Nickel (Ni) 0 to 0.5
Molybdenum (Mo) 0 to 0.5
Copper (Cu) 0 to 0.5
Phosphorus (P) 0 to 0.050
Sulfur (S) 0 to 0.050
Aluminum (Al) 0 to 0.050
Carbon (C) 0 to 0.030
