ASTM Grade LC2-1 Steel vs. Grade TDC Steel

Both ASTM grade LC2-1 steel and grade TDC steel are iron alloys. They have a very high 95% of their average alloy composition in common. There are 26 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 grade LC2-1 steel and the bottom bar is grade TDC steel.
