Heat a sample to just over non-magnetic and let cool in free air or gentle breeze. Test the hardness with a file. If the piece is very hard then it is probably a high carbon tool steel above 100 points carbon. If it didn't air harden, heat a sample to just over non-magnetic and then quench in oil. Blacksmiths guide to using junk yard steels :Using Heat a sample to just over non-magnetic and let cool in free air or gentle breeze. Test the hardness with a file. If the piece is very hard then it is probably a high carbon tool steel above 100 points carbon. If it didn't air harden, heat a sample to just over non-magnetic and then quench in oil.
