Annealed AISI 201LN vs. Annealed ASTM B522 Class I

Annealed AISI 201LN belongs to the iron alloys classification, while annealed ASTM B522 class I belongs to the otherwise unclassified metals. There are 22 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is annealed AISI 201LN and the bottom bar is annealed ASTM B522 class I.
