ASTM A228 Music Wire vs. N08031 Stainless Steel
Both ASTM A228 music wire and N08031 stainless steel are iron alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.
For each property being compared, the top bar is ASTM A228 music wire and the bottom bar is N08031 stainless steel.
