Features & Benefits

Base Chemicals Features
Features
  • Hardenability - the molybdenum level of Atomet 4001 enhances heat-treated properties without sacrificing compressibility.
    • Improved hardness and tensile strength.
  • Compressibility - the outstanding compressibility of Atomet 4001 extends the benefits of low alloy compositions to high-density applications above 7.0 g/cm3.
    • Higher strength, higher density PM parts.
    • Reduced tool stress.
  • Consistency- lot-to-lot consistency is ensured by a stable ore-based feedstock, modern steelmaking practices and statistically controlled manufacturing processes.
    • Low part-to-part variation.
  • Purity and cleanliness- unique ore-based feedstock and state-of-the-art clean steel practice ensure low residuals and exceptional cleanliness.
    • Improved mechanical and dynamic properties of PM and PF parts.
    • Improved machinability of PM and PF parts.
