Heat Treating Instructions (1084 Core)

Forge/Fabrication Notes:

• Forging range: 815–1200°C (1500–2200°F)
• Do not forge below 815°C to prevent cracking.
• Normalize after forging to refine grain and relieve stress.

Normalization:

1. Heat to 870°C (1600°F), air cool.
2. Reheat to 830°C (1525°F), air cool.
3. Final cycle at 760°C (1400°F), air cool to room temperature.

Austenitising:

• Heat evenly to 800–830°C (1475–1525°F) and hold for ~5 minutes.
• Avoid overheating—1084 is simple carbon steel and sensitive to grain growth above 830°C.

Quench:

• Quench immediately in fast oil (e.g. Parks 50 or Houghton K).
• Warm oil (40–60°C) helps reduce shock and warping.

Tempering:

• Temper as soon as the blade is cool to touch (~50°C).
• Recommended range: 150–220°C (300–430°F) for 58–62 HRC depending on desired hardness and use.
• Double temper for 1 hour per cycle.

Optional Finishing Notes:

• For best results, lightly sand and etch after heat treat to bring out the San Mai contrast.
• Cladded steels may warp slightly—straighten gently while warm from quench if needed.
