Half-hard AISI 205 vs. Half-hard ASTM B617

Half-hard AISI 205 belongs to the iron alloys classification, while half-hard ASTM B617 belongs to the otherwise unclassified metals. There are 17 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.

For each property being compared, the top bar is half-hard AISI 205 and the bottom bar is half-hard ASTM B617.
