* Properties listed were obtained on flat tensile specimens. They are considered typical, and are for information only. Properties may vary somewhat on actual parts, depending on size, shape, and processing variables.
|
|
** Composite hardness of pores and solid material, hence hardness value is somewhat lower than comparable wrought material.
|
|
*** Unnotched Charpy impact test perpendicular to pressing direction.
|
|
High density materials with low combined carbon may be effectively case hardned. Control of carburized case depth in ferrous P/M materials is dependent upon density. Lower density parts will through harden.
