Half-Hard N08800 Stainless Steel

Half-hard N08800 stainless steel is N08800 stainless steel in the half-hard temper. The graph bars on the material properties cards below compare half-hard 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.
