Grade G3000 Cast Iron vs. ASTM Grade HT Steel
Both grade G3000 cast iron and ASTM grade HT steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 48% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.
For each property being compared, the top bar is grade G3000 cast iron and the bottom bar is ASTM grade HT steel.
