ASTM A372 Grade K Steel vs. ASTM Grade LCC Steel
Both ASTM A372 grade K steel and ASTM grade LCC steel are iron alloys. They have a very high 96% of their average alloy composition in common. There are 30 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
For each property being compared, the top bar is ASTM A372 grade K steel and the bottom bar is ASTM grade LCC steel.
