N08031 Stainless Steel vs. SAE-AISI 5147 Steel

Both N08031 stainless steel and SAE-AISI 5147 steel are iron alloys. Both are furnished in the annealed condition. They have a modest 35% of their average alloy composition in common, which, by itself, doesn't mean much. There are 28 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is N08031 stainless steel and the bottom bar is SAE-AISI 5147 steel.
