anclajes PLX

PLX is the name Fixe has given to the well-known Duplex 2205 stainless steel. This material has a two-phase micro-structure of ferritic steel and austenitic stainless steel. PLX arises from the combination of the two materials.

PLX has some outstanding properties:

  • Strength. PLX is nearly twice as strong as austenitic stainless steel.
  • Corrosion-resistance. PLX has ranges of resistance to common corrosion that are slightly higher than those of A4 (316) stainless steel.
  • Resistance to stress corrosion cracking (SCC). PLX, due to its two-phase micro-structure, provides greater resistance to SCC. Stress corrosion cracking may result in sudden breakage with common austenitic steels (A2 and A4).

Why does Fixe use PLX in its entire range of anchors?

The UIAA (International Climbing and Mountaineering Federation) has been warning the climbing community for several years about the danger of some climbing routes where SCC (Stress Corrosion Cracking) occurs.

This warning arises from investigations into several climbing accidents in which the main cause of the accident was SCC corroded anchors.

Due to these SCC-induced accidents, at Fixe we have opted for PLX, a material with a resistance to SCC exceeding that of stainless steels 304 and 316.

Fixe bases its decision to use PLX on the following:

  • European standards, public studies by technical associations and various scientific publications.
  • Multiple product tests and trials to achieve the main objective: increase corrosion-resistance and prevent future failures due to SCC.

In short, PLX anchors better resist environmental conditions than 304 and 316 steels, prolonging the longevity of the material installed in walls.

Fixe is committed to continuously studying materials and production processes in order to offer the climbing community the best possible products in terms of safety.

Fixe is leading the way in research, working alongside the European scientific community, the UIAA (International Climbing and Mountaineering Federation) and material research centres.
