Hot Finished N08800 Stainless Steel
Hot finished N08800 stainless steel is N08800 stainless steel in the hot worked condition. It has the lowest strength compared to the other variants of N08800 stainless steel.
The graph bars on the material properties cards below compare hot finished N08800 stainless steel to: wrought superaustenitic 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.
