Annealed SAE-AISI L2 vs. Annealed AISI W1
Both annealed SAE-AISI L2 and annealed AISI W1 are iron alloys. Both are furnished in the annealed condition. They have a very high 99% of their average alloy composition in common.
For each property being compared, the top bar is annealed SAE-AISI L2 and the bottom bar is annealed AISI W1.
