UNS S46910 Stainless Steel
S46910 stainless steel is a precipitation-hardening stainless steel formulated for primary forming into wrought products.
It can have the highest tensile strength among wrought precipitation-hardening stainless steels. In addition, it has a moderately high base cost and a moderately high embodied energy.
The properties of S46910 stainless steel include five common variations. This page shows summary ranges across all of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare S46910 stainless steel to: wrought precipitation-hardening 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.
