ASTM A182 Grade FR vs. Grade TDC Steel

Both ASTM A182 grade FR and grade TDC steel are iron alloys. They have a very high 97% 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 A182 grade FR and the bottom bar is grade TDC steel.
