Description: AFM 700 offers a harder weld deposit than AFM 600, but lacks the corrosion resistance. Primarily used for high metal to metal abrasion. Weld deposits are martensitic in structure and will work harden when put into service. Excellent impact resistance; excellent abrasion resistance.
Applications: Rollers, conveyor screws, crusher rolls, and mill hammers.
Typical Chemical Composition:
- Carbon (C) - 0.30
- Silicon (Si) - 2.40
- Manganese (Mn) - 0.50
- Chromium (Cr) - 7.00
- Molybdenum (Mo) - 0.70
- Iron Base (Fe) - BAL
Procedure: Use DC Reverse Polarity (electrode positive). The shielding gas should be 100% CO©÷ welding grade, however a 75% Argon/25% CO©÷ mixture will increase the hardness
slightly. Superior properties are achieved if an interpass temperature of 300¡Æ-480¡ÆF is maintained. Yield the smoothest performance.
Standard Diameters & Packaging:
