Grade 365 Molybdenum
Grade 365 molybdenum is a molybdenum alloy. Cited properties are appropriate for the stress relieved condition. It has a fairly high tensile strength among the alloys in the same category in the database.
The graph bars on the material properties cards below compare grade 365 molybdenum to: molybdenum alloys (top), all alloys in the same category (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.
