Ameralloy® -FH Flame Hardening

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.

Typical Analysis

  • Carbon .30
  • Manganese .75
  • Chromium 1.10
  • Silicon .45
  • Molybdenum .35
  • Copper .50

Features And Advantages

  • Minimum decarburization
  • Safe–will not mushroom or chip
  • Wider range of hardness
  • Shock resistant
  • 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

Heat Treatment

  • Forging 1900°–2150°F, stop at 1700°F
  • Annealing 1400°F, slow furnace cool, Brinell 197
  • Hardening 1500°–1850°F, water or oil-quench
  • Tempering 300°–1300°F, Brinell 534–241
