Conclusions

  1. 1.

    To increase the strength of steel ON9A it must be alloyed with molybdenum (0.25–0.4%).

     
  2. 2.

    Steel ON9A has a high strenght at 20°C (σb ≈ 90−100 kg/mm2, σ0.2 = 65−75 kg/mm2) in combination with satisfactory plasticity and toughness at −196°C (ψ∼50%,an∼6–7 kg-m/cm2).

     
  3. 3.

    Steel ON9MA is suited for drop forging, bending, and drawing.

     
  4. 4.

    Steel ON9MA is welded with argon-arc welding, using ÉP260 filler wire (Kh10N20M10T2). The welded samples do not require heat treatment.
