STAINLESS STEEL OPEN SPIRAL STRAND (OSX)
OSX cables are manufactured using layers of helically wound stainless steel round wires around a central core. The standard stainless-steel grade used to produce OSX is 1.4401 (AISI 316). Each wire has a minimum tensile strength of 1470 N/mm2. Stainless steel cables do not need for an internal corrosion inhibitor compound. Therefore, they are usually produced dry or with a light manufacturing oil.
- High axial stiffness
- High strength to weight ratio
- High fatigue resistance
- Torque balanced
- Teufelberger-Redaelli patented anti-vibration solution (Surface Treatment)
Mechanical characteristics of steel wires:
- Nominal Tensile Strength 1450 Mpa (after hot dip galvanizing)
- Proof Stress Rp 0.2 1080 Mpa
- Modulus of Elasticity 130 ± 10kN/mm²
Teufelberger-Redaelli Stainless Steel Open Spiral Strands (OSX) are manufactured using layers of helically wound stainless steel round wires around a central core.
Each individual wire is tested and verified for tensile strength, ductility, elongation at fracture, bending and torsional properties in accordance with EN 10264. Main properties: high axial stiffness, high strength to weight ratio, high fatigue resistance, torque balanced.
