ASTM Grade LC9 Steel vs. Grade TDC Steel

Both ASTM grade LC9 steel and grade TDC steel are iron alloys. They have a moderately high 90% of their average alloy composition in common. There are 24 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is ASTM grade LC9 steel and the bottom bar is grade TDC steel.
