Grade 3 Babbitt Metal vs. Grade 2 Babbitt Metal
Both grade 3 Babbitt Metal and grade 2 Babbitt Metal are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 95% of their average alloy composition in common.
For each property being compared, the top bar is grade 3 Babbitt Metal and the bottom bar is grade 2 Babbitt Metal.
