Hot Worked Monel 400
Hot worked Monel 400 is Monel 400 in the hot worked condition. The graph bars on the material properties cards below compare hot worked Monel 400 to: wrought nickels (top), all nickel 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.
