When it comes to components requiring high strength, durabilidad, and spring-like properties, few materials perform as reliably as tiras de acero endurecido y templado. From saw blades to shutter springs, this specialized steel undergoes a rigorous heat treatment process to achieve the perfect balance between hardness and toughness—a balance critical to performance in demanding environments.
En este artículo, we break down what hardened and tempered steel strips are, how they’re made, and where they’re used—offering practical insight for engineers, buyers, and manufacturers across industries.
? What is Hardened and Tempered Steel Strip?
Hardened and tempered steel strip refers to steel that has undergone a two-stage heat treatment process:
- Endurecimiento – Steel is heated above its critical temperature and then rapidly cooled (apagado), transforming its internal structure to become very hard but also brittle.
- Templado – The hardened steel is reheated to a lower temperature and held for a controlled time. This reduces brittleness while retaining high hardness, improving toughness and elasticity.
The result? A steel strip that resists wear, holds shape under stress, and delivers long-term reliability in mechanical or spring-loaded applications.
? How It’s Made: JiaxiaoMTC’s Precision Process
En Tecnología de materiales Jiaxiao Co., Limitado., hardened and tempered strips are produced using a vertically integrated process with strict control over:
- Raw material: High-quality hot rolled coils from ISO-certified mills
- laminación en frío: To achieve tight thickness and width tolerances
- Tratamiento térmico: Precision quenching and tempering in inert atmosphere
- Edge finishing: Abertura, cuadrado, or round edges for safety and function
- Acabado superficial: Natural, azul, amarillo, blanco, o pulido, per application
Rango de tamaño:
- Espesor: 0.10 mm a 5.00 milímetros
- Ancho: 2 mm a 500 milímetros
- Dureza: 30–55 HRC
This meticulous process ensures the strip steel is not only dimensionally accurate but also mechanically consistent—an essential factor for critical components.
? Applications of Hardened & Tira de acero templado
These steel strips are widely used across industries where load-bearing, spring-back, or cutting properties are required:
- Resortes de obturador
- Band saw blades and knives
- Espátulas para masilla, paletas, scrapers
- Shoe insoles and toe caps
- Flat springs and clips
Especially in shutter springs, JiaxiaoMTC’s C67S, C75S, y C80 spring steel strips are praised for their resilience and flexibility—critical qualities that ensure the spring bends without breaking under repeated stress.
? Why Choose Hardened Steel Over Annealed?
| Propiedad | Curtido & Tempered Strip | Cold Rolled Annealed Strip |
|---|---|---|
| Dureza | Alto (30–55 HRC) | Low (máximo 180 alto voltaje) |
| Flexibilidad (Springback) | Excelente | Limited |
| Resistencia al desgaste | Superior | Moderado |
| Formabilidad | Moderado | Excelente |
| Use After Shaping | Sí | Needs post-forming treatment |
If your product needs high surface durability, resistance to deformation, o precise mechanical performance, hardened and tempered steel is the ideal solution.
