1/16-Hard 301LN Stainless Steel
1/16-hard AISI 301LN is AISI 301LN stainless steel in the 1/16-hard temper. It has the second lowest strength and second highest ductility compared to the other variants of AISI 301LN stainless steel.
The graph bars on the material properties cards below compare 1/16-hard AISI 301LN 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.
