Base Chemicals Features
Features
  • Hardenability - Atomet 4201, containing a precise level of manganese, nickel and molybdenum, is an ideal choice for powder metallurgy (PM) and powder forging (PF) applications that require consistent and superior heat-treated properties.
    • Improves hardness and tensile strength.
  • Dimensional change - Atomet 4201 can be used with existing tooling designed for conventional AISI 4200 pre-alloyed powders.
    • No need to retool.
  • Consistency - a stable ore base, modern steelmaking practices and statistically controlled powder manufacturing ensure lot-to-lot consistency. Being a homogeneous alloy, Atomet 4201 eliminates the detrimental effects of segregation and dusting normally associated with elemental blends.
    • Low variation of part properties.
    • Compatible with work environment requirements.
  • Compressibility - the outstanding compressibility of Atomet 4201 extends the benefits of pre-alloyed powders thigh density applications above 6.9 g/cm3
    • Reduces tool stress
    • Improves strength
  • Purity and cleanliness - state-of-the-art clean steel practice ensures low residuals and sets new standards for cleanliness.
    • Improves mechanical and dynamic properties
