Thank god for your videos on metals, thank you :). You change the 3 (n) values to go from Iron to Steel but where did you find the Steel 0.911, 0.95 and 0.585 values.?

Hi, I'm glad they help. The issue with steel is that it's an alloy, so when you see me change the values I'm just eyeballing it to get it to the amount I think is correct. As it's an alloy there are so many different mixes of metals that it's not going to be completely scientific. It just always depends on how the steel was made, so the easiest solution is to try to match a reference, either photo or something you have in front of you.
