Maraging Steel 1

Description:

Maraging Steel 1 is a pre-alloyed ultra-high-strength steel in fine powder form. Its composition corresponds to U.S. classification 18% Ni Maraging 300, European 1.2709 and German X3NiCoMoTi 18-9-5. This kind of steel is characterized by having very good mechanical properties and being easily heat treatable using a simple thermal age-hardening process to obtain excellent hardness and strength.

Applications:

  • Heavy-duty injection molds and inserts for molding all standard thermoplastics using standard injection parameters, with achievable tool life of up to millions of parts
  • Die-casting molds for up to several thousand parts in light alloys
  • Direct manufacture of part for engineering applications including functional prototypes, small series products, individualized products, or spare parts
  • Parts requiring particularly high strength and hardness
