The Strength That Never Backs Down
When stresses are high, continuous, and severe, you need a material that doesn’t take a step back. This is the steel for the most demanding applications.
42CrMoS4+QT+C Chromium-Molybdenum Alloy Steel
- 42: Carbon content
- Cr: Chromium
- Mo: Molybdenum
- S4: Controlled sulfur content for improved machinability
- QT: Quenched and Tempered (Bonificato)
- +C: Cold drawn
It features mechanical characteristics typical of Class 10.9 and is the most resistant material among those commonly available at Zarri.
Zarri uses it for structural tie rods, fixings for bridges and infrastructure, wind power systems, heavy machinery, and high-stress applications, while also guiding the customer in choosing the most suitable anti-corrosion treatments.
