Color Code: GRAY
Ameralloy-FH was specially developed to withstand severe wear and resist galling. The application of Ameralloy-FH will result in a more uniform section after hardening, without shrinking. Ameralloy-FH can be hardened by quenching and tempering, flame hardening, or carburizing. Ameralloy-FH was engineered to produce a perfect hand tool with inexperienced help, or where there is a lack of adequate heat-treating facilities. Ameralloy-FH can be reworked at the forge without cracking or changing physical properties.

- Extremely tough
- No tempering required
General Instructions
Annealing If machining is to follow forging, anneal by heating to 1400°F (cherry-red), cool to 900°F, then air cool.
Hardening Allow tool to cool after forging. Reheat to 1550°–1850°F (salmon-to-orange range) and quench in water.
Toughen striking end In the as-forged condition, the striking end should be tapered and heated to 1325°F (cherry-red), and quenched in water. This insures elimination of mushrooming.
Forging Forge at 1800°–2000°F. Discontinue operation when temperature falls below 1800°F and reheat again. After forging, the piece should be air cooled. Ameralloy-FH will have the following physical properties:
– Yield point: 96,000 lbs. psi
– Tensile strength: 152,000 lbs. psi
– Elongation in 2”: 18%
– Reduction of area: 46%
– Brinell hardness: 320
