Cold Rolled EN 1.4371 vs. Cold Rolled EN 1.4482

Both cold rolled EN 1.4371 and cold rolled EN 1.4482 are iron alloys. Both are furnished in the cold worked (strain hardened) condition. They have a very high 96% of their average alloy composition in common. There are 32 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is cold rolled EN 1.4371 and the bottom bar is cold rolled EN 1.4482.
