When it comes to components requiring high strength, độ bền, and spring-like properties, few materials perform as reliably as dải thép cứng và tôi luyện. From saw blades to shutter springs, this specialized steel undergoes a rigorous heat treatment process to achieve the perfect balance between Độ cứng và độ dẻo dai—a balance critical to performance in demanding environments.
Trong bài viết này, 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?
Dải thép cứng và tôi luyện refers to steel that has undergone a two-stage heat treatment process:
- Hardening – Steel is heated above its critical temperature and then rapidly cooled (dập tắt), transforming its internal structure to become Rất khó Nhưng cũng vậy brittle.
- Ủ – 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.
Kết quả? 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
Tại Jiaxiao Material Technology Co., Ltd., 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
- Cold rolling: To achieve tight thickness and width tolerances
- Xử lý nhiệt: Precision quenching and tempering in inert atmosphere
- Edge finishing: Khe hở, quảng trường, or round edges for safety and function
- Surface finish: Natural, màu xanh da trời, màu vàng, trắng, or polished, per application
Size Range:
- Độ dày: 0.10 mm to 5.00 mm
- Chiều rộng: 2 mm to 500 mm
- Độ cứng: 30–55 HRC
This meticulous process ensures the strip steel is not only dimensionally accurate Nhưng cũng vậy mechanically consistent—an essential factor for critical components.
? Applications of Hardened & Dải thép cường lực
These steel strips are widely used across industries where load-bearing, spring-back, or cutting properties are required:
- Rolling shutter springs
- Band saw blades and knives
- Putty knives, Trowels, scrapers
- Shoe insoles and toe caps
- Flat springs and clips
Especially in shutter springs, JiaxiaoMTC’s C67, 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?
| Tài sản | Cứng & Tempered Strip | Cold Rolled Annealed Strip |
|---|---|---|
| Độ cứng | Cao (30–55 HRC) | Thấp (max 180 HV) |
| Linh hoạt (Springback) | Xuất sắc | Limited |
| Wear Resistance | Superior | Vừa phải |
| Formability | Vừa phải | Xuất sắc |
| Use After Shaping | Yes | Needs post-forming treatment |
If your product needs high surface durability, resistance to deformation, or precise mechanical performance, hardened and tempered steel is the ideal solution.
