When it comes to components requiring high strength, долговечность, and spring-like properties, few materials perform as reliably as полосы из закаленной и отпущенной стали. 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.
В этой статье, 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?
Полоса из закаленной и отпущенной стали refers to steel that has undergone a two-stage heat treatment process:
- Закалка – Steel is heated above its critical temperature and then rapidly cooled (quenched), transforming its internal structure to become very hard but also brittle.
- Закалка – 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
В Jiaxiao Material Technology Co., ООО., 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
- Холодная прокатка: To achieve tight thickness and width tolerances
- Термическая обработка: Precision quenching and tempering in inert atmosphere
- Edge finishing: щель, квадрат, or round edges for safety and function
- Чистота поверхности: Natural, синий, желтый, белый, или полированный, per application
Size Range:
- Толщина: 0.10 mm to 5.00 мм
- Ширина: 2 mm to 500 мм
- Твердость: 30–55 HRС
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 & Полоса из закаленной стали
These steel strips are widely used across industries where load-bearing, spring-back, or cutting properties are required:
- Прокачивание затвора
- Band saw blades and knives
- Шпатели, мастерки, скребки
- Shoe insoles and toe caps
- Flat springs and clips
Especially in shutter springs, JiaxiaoMTC’s C67S, C75S, and 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?
| Property | Закаленный & Tempered Strip | Cold Rolled Annealed Strip |
|---|---|---|
| Твердость | Высокий (30–55 HRС) | Low (max 180 HV) |
| Гибкость (Springback) | Excellent | Limited |
| Wear Resistance | Superior | Moderate |
| Formability | Moderate | Excellent |
| Use After Shaping | Да | Needs post-forming treatment |
If your product needs high surface durability, resistance to deformation, или precise mechanical performance, hardened and tempered steel is the ideal solution.
