Did you mean determine manganese content in steel by converting it to permanganate and measuring it using visible spectroscopy?
If so it is a standard method in many classical analytical text books. To read a recent paper on the subject see Ramachandra & Rashmi, The Analyst, Volume 124, 1099-1103 (1999)

Primarily iron, with some carbon and nickel in the alloy. The precise proportions will determine the properties of the resulting steel.
Reprocessed steel cents lack detail and appear to be filled in some even show wear and corrosion.
Go to the sink.
yes
The answer to that is not known at this time, but I would be happy to determine the answer and get back to you.
To determine the age of the instrument, a serial number is needed.
A genuine 1944 steel cent is worth thousands of dollars. One sold at auction in 2008 for $373,750. To determine if a 1944 cent is steel or zinc-coated copper, test it with a magnet. Copper is not magnetic.
In order to weld pieces of 6mm steel you can use any type of welder. Depending on how strong and how pretty the weld needs to be will determine the type of welder you choose.
without better grammar, I cannot determine exactly what is the question....
Cannot determine without also knowing the gauge or other equivalent cross-sectional area.
