EN 1.4713 (X10CrAlSi7) Stainless Steel

EN 1.4713 stainless steel is a ferritic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 1.4713 is the EN numeric designation for this material. X10CrAlSi7 is the EN chemical designation.

It has the lowest base cost among wrought ferritic stainless steels. In addition, it has the lowest embodied energy and a moderately low ductility.

The graph bars on the material properties cards below compare EN 1.4713 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 1.4713 stainless steel is notable for including aluminum (Al). Aluminum is used to improve oxidation resistance. It can also enhance the effects of heat treatment.

Iron (Fe) 88.8 to 93
Chromium (Cr) 6.0 to 8.0
Silicon (Si) 0.5 to 1.0
Aluminum (Al) 0.5 to 1.0
Manganese (Mn) 0 to 1.0
Carbon (C) 0 to 0.12
Phosphorus (P) 0 to 0.040
Sulfur (S) 0 to 0.015
