Whoever you are nameless nobody, a man of steel and tool and die making this
afternoon described very clearly how to differentiate between 4130 and mild
steel. I googled with "ferrous metals" and "spark test" and he's right.

Who gives a ****e what YOU think; you're just a nobody.

Most tool and die people are. However spark test is only in the 30%
bracket for uncertainty, meaning 70% chance that you're going to be
wrong. But that's normal for you, although I think I should give you
another 20%, there's a 90% chance that you'd screw up.

If you go back and read it, spark testing is only for steels in a
given state, and you have no idea even where to start to find what
state your steel is in. Nor would you know the difference.

And by the way, when you take that chromoly into a lab, maybe checking
for chromium and molybdenum might be better choices. Possibly the
name of the steel gives away a little of it's composition. But what
would you care? You're not interested in truth, just in feeding your
fat head.

I may be a nobody, but you're a nobody that's making a fool out of
himself on this group, again, and again, and again, and,,,,

Have a nice day, clap drip.
