File Test

The fastest & easiest method of testing the carbon content of an unknown type steel without the use of chemicals or special equipment is by using any workshop file.

Steel Type	Carbon Content	File Reaction
Mild	less than 0.15%	Bites metal easily
Medium Carbon	0.15% to 0.25%	Bites with pressure
High Alloy	0.26 to 0.35 %	Bites only with force
Tool	0.36 to 0.45%	Bites with difficulty
Hardened Tool	Over 0.45%	Slides over metal
