Hot Finished 310 Stainless Steel

Hot finished AISI 310 is AISI 310 stainless steel in the hot worked condition. The graph bars on the material properties cards below compare hot finished AISI 310 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.
