Hardened and tempered steel strips are essential materials in industries that demand high strength, durability, and flexibility. Produced through a precise quenching and tempering process, these strips combine hardness with toughness, making them ideal for ressorts, saw blades, knives, and construction tools.
What Are Hardened and Tempered Steel Strips?
The hardening process involves heating steel strips above the critical transformation temperature and rapidly cooling them to increase hardness. However, this makes the steel brittle.
To improve flexibility, the strips undergo tempering, where they are reheated at a lower temperature and cooled under controlled conditions. This treatment balances hardness and toughness, creating a material that resists breakage while maintaining strength.
Key Properties
- Hardness Range – 30–55 HRC, adjustable depending on application.
- High Elasticity – Perfect for springs that require repeated bending.
- Wear Resistance – Longer tool life in cutting and scraping applications.
- Surface Options – Available in natural, blue, yellow, polished, or white finishes.
- Edge Types – Slit, rounded, or square edges for specific needs.
Industrial Applications
- Rolling Shutter Springs – Require flexibility and strength to operate daily without breaking.
- Saw Blades – Band saw blades, circular saws, and hacksaw blades all rely on hardened steel for sharpness and durability.
- Knives and Cutting Tools – Putty knives, scrapers, and industrial blades.
- Construction Tools – Trowels and other hand tools benefit from high toughness.
With proper edge treatment and polishing, these strips deliver consistent results across industries.
