EN 1.4017 (X6CrNi17-1) Stainless Steel
EN 1.4017 stainless steel is a ferritic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 1.4017 is the EN numeric designation for this material. X6CrNi17-1 is the EN chemical designation.
It has a fairly high thermal conductivity among wrought ferritic stainless steels. In addition, it has a fairly low ductility and a moderately high tensile strength.
The graph bars on the material properties cards below compare EN 1.4017 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 1.4017 stainless steel is notable for containing comparatively high amounts of chromium (Cr) and nickel (Ni). Chromium is the defining alloying element of stainless steel. Higher chromium content imparts additional corrosion resistance. Nickel is primarily used to achieve a specific microstructure. In addition, it has a beneficial effect on mechanical properties and certain types of corrosion.
