InfiniSpring

Advancing performance through material innovation.

InfiniSpring has been testing spring solutions at SEAMK - Seinäjoki University of Applied Sciences using SSAB Hardox® steel, with very strong results.

In this video, we demonstrate a spring made from 2 mm Hardox® 450 (ultra-high-strength wear-resistant steel). While the geometry matches our standard 3 mm spring, the higher material strength (~1350 MPa yield) enables:

✅ Reduced thickness with higher strength
✅ ~50% lower stiffness → softer spring behavior
✅ Improved low-frequency isolation performance

Both the standard and Hardox® versions are optimized for 15–25 kg load ranges, delivering excellent low-frequency noise, vibration, and shock performance, with enhanced performance achieved using ® material in demanding applications.

A key observation from testing was the excellent plastic deformation performance: even under significant stress, the spring itself did not fail. Instead, the steel rivet failed at ~2480 N, highlighting the robustness of the Hardox®-based design.

Proud to see InfiniSpring highlighted by SSAB.

Our focus is on improving structural performance across vibration, shock and sound — enabling new possibilities in building and industrial applications.

We have recently tested Hardox with very encouraging results and will share more soon.

Exciting developments ahead.
