Grade 363 Molybdenum
Grade 363 molybdenum is a molybdenum alloy. It can have a moderately high tensile strength among the alloys in the same category in the database.
The properties of grade 363 molybdenum include two common variations. This page shows summary ranges across both of them. For more specific values, follow the links immediately below. The graph bars on the material properties cards further below compare grade 363 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.
