Definitions

  • the invention relates to a corrosion-resistant and / or corrosion-inhibiting material and its production in the form of profiled wires for special use as alpine ski edges.
  • Stainless steels according to the AISI series 300 and 400 standards are known for their use as a corrosion-resistant material in chemical apparatus engineering. However, their use is often restricted by their mechanical properties.
  • edges are particularly important in alpine ski construction, as they have to bear up to 30% of the total breaking and bending strength of the ski.
  • Alpine ski edges are generally made from rust-proof, unalloyed carbon steels. This leads to excessive wear on the ski edges, which in turn results in a shorter lifespan for alpine skis. This Excessive wear also poses a safety risk for the user.
  • the aim of the present invention is to supply the rustproof and acid-resistant AISI series 300 and 400 high-alloy steels to alpine skiing.
