Hot Finished 317 Stainless Steel
Hot finished AISI 317 is AISI 317 stainless steel in the hot worked condition. The graph bars on the material properties cards below compare hot finished AISI 317 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.
