AISI 410S (S41008) Stainless Steel
AISI 410S stainless steel is a martensitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition. 410S is the AISI designation for this material. S41008 is the UNS number.
It has a moderately low embodied energy among wrought martensitic stainless steels. In addition, it has the lowest tensile strength and a fairly high ductility.
The graph bars on the material properties cards below compare AISI 410S stainless steel to: wrought martensitic 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 AISI 410S stainless steel is notable for containing comparatively high amounts of chromium (Cr) and manganese (Mn). Chromium is the defining alloying element of stainless steel. Higher chromium content imparts additional corrosion resistance. Manganese is used to improve ductility at elevated temperatures. It also permits a higher nitrogen content than would otherwise be possible.
