Annealed ASTM B596 vs. Annealed SAE-AISI T4
Annealed ASTM B596 belongs to the otherwise unclassified metals classification, while annealed SAE-AISI T4 belongs to the iron alloys. There are 15 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.
For each property being compared, the top bar is annealed ASTM B596 and the bottom bar is annealed SAE-AISI T4.
