EN45 Spring Steel Flat covers cold-rolled flat products supplied in annealed or hardened and tempered condition for springs, clips, blades, washers and precision engineering parts.
Spring steel is a medium-to-high carbon or alloy steel that can be heat treated to achieve high yield strength, allowing parts to return to shape after significant deflection.
Product range
- Annealed Strips — Soft condition for forming and further heat treatment.
- Hardened & Tempered Strips — Ready-to-use strips with high hardness and elasticity.
- Polished / Blue Strips — Surface-finished strips for special applications.
- Spring Steel Flats — Heavier flats for leaf springs and heavy-duty parts.
Why engineers choose it
- High Elasticity — Returns to shape after bending or twisting.
