UNS S30435 Stainless Steel
S30435 stainless steel is an austenitic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition.
It has a fairly low tensile strength among wrought austenitic stainless steels. In addition, it has a fairly high ductility and a moderately low embodied energy.
The graph bars on the material properties cards below compare S30435 stainless steel to: wrought austenitic 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.
