UNS S42035 Stainless Steel
S42035 stainless steel is a ferritic stainless steel formulated for primary forming into wrought products. Cited properties are appropriate for the annealed condition.
It has a fairly high tensile strength among wrought ferritic stainless steels. In addition, it has a fairly low ductility and a moderately high thermal conductivity.
The graph bars on the material properties cards below compare S42035 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.
