A Practical Guide for Engineers, Buyers, and Manufacturers
Steel strips are essential components in a wide range of industries—from cutting tools and automotive parts to springs, лезвия пилы, and measuring tools. Однако, with so many types of steel strips available on the market, selecting the right one can be a real challenge.
This guide will walk you through the key factors to consider when choosing a steel strip, helping you match the right material to your specific application.
? 1. Understand the Application First
The starting point is always the intended use. Ask yourself:
- Will the strip be used in high-stress environments (например, источники, лезвия пилы)?
- Is surface finish critical (например, decorative or visible parts)?
- Does the part need to be formed, bent, or deep drawn?
Your answers will help narrow down the choices between отожженный, cold-rolled, или закаленный и закаленный стальные полосы.
? 2. Material Type: Углеродистая сталь, Легированная сталь, or Stainless?
▸ High Carbon Steel Strip
- Excellent hardness and strength after heat treatment
- Common grades: 65Мин., СК5, C75S
- Used for cutting tools, источники, лезвия
▸ Alloy Steel Strip
- Offers improved wear resistance and fatigue strength
- Examples: 50КрВ4, 51CrMoV4
- Ideal for automotive and high-performance components
▸ Stainless Steel Strip
- Corrosion-resistant, excellent for harsh environments
- Grades like 301, 304, 420, и 430 available
- Perfect for kitchenware, medical tools, or humid settings
? 3. Heat Treatment Condition
Steel strips come in different conditions, mainly:
| Type | Характеристики | Приложения |
|---|---|---|
| Отожженный | Мягкий, easy to form and bend | Deep drawing, stamping, сварка |
| Закаленный & Закаленный | Высокая прочность и износостойкость | Лезвия, источники, измерительные инструменты |
If post-forming hardening is not an option, pre-hardened steel (ЧАС&Т) is your best bet.
? 4. Точность размеров & Толерантность
Precision matters. Define:
- Толщина (например, 0.2mm to 3.0mm)
- Ширина (например, 6mm to 450mm)
- Допуски (±0.01mm or tighter for precision applications)
Check whether your supplier can offer tight tolerance cold rolling или slit-edge quality that matches your requirements.
? 5. Surface Finish Requirements
Surface finish is more than aesthetics—it affects corrosion resistance and tooling compatibility.
- Bright finish: Smooth and reflective, often used in visible parts
- Blue/Yellow Tempered: Achieved through oxidation during tempering, offers added surface protection
- Matte or Dull Finish: For painting or coating applications
Some suppliers also offer oiled, dry, или plastic-film-covered surfaces based on usage conditions.
✅ 6. International Standards and Certifications
Make sure the steel strip complies with relevant standards:
- DIN EN 10132 – Cold rolled narrow steel strip for heat treatment
- АСТМ А684 – High carbon steel strip standards
- ИСО 683-17 – For quenched and tempered steels
And don’t forget to check for supplier certifications like ISO 9001 or IATF 16949.
