Product description

BÖHLER M121 ISOPLAST is a remelted nickel chrome molybdenum case hardening steel produced by the PESR (Pressurised ESR) method designed for components with high demand in toughness and core strength.

Property features

  • Best fatigue strength and toughness properties as well as outstanding tensile strength
  • Good dimensional stability, thereby low distortion
  • High cleanliness level for best homogeneity
  • 100% ultrasonically tested pre-material
  • No hydrogen increases during remelting reduces the danger of cracking
  • Tight elemental control, precise adjustment of alloying element contents
