Data Chart for Marking
This chart estimates the tonnage requirements for marking mild steel. To
use, multiply the proper tonnage by the number of characters to be stamped.

* To determine pressures for aluminum or brass multiply the above tonnage
by 0.7.
For high carbon steel, multiply by 1.5.
** To determine other impression depths, mulitply
the tonnage by the following:
1/2 of depth -- 0.7
2 times depth -- 1.3
3 times depth -- 1.7
