24 Tolok Keluli Tahan Karat Lembaran Logam
24 gauge stainless steel sheet metal has a nominal thickness of approximately 0.6 mm, but the actual thickness varies according to production tolerance standards. Dalam kebanyakan kes, the actual thickness range is approximately 0.55 mm ke 0.65 mm depending on manufacturing precision and international standards.
- Penerangan
24 gauge stainless steel sheet metal is a thin stainless steel material widely used in HVAC systems, peralatan dapur, panel hiasan, fabrikasi ketepatan, dan aplikasi industri ringan. Because stainless steel sheet thickness is affected by manufacturing tolerances and different gauge standards, the actual thickness may vary slightly from the nominal gauge value.
Understanding the tolerance range of 24 gauge stainless steel is important for fabrication accuracy, mengimpal, membengkok, and assembly applications.
1. Nominal Thickness of 24 Tolok Keluli Tahan Karat
Under common stainless steel gauge systems:
| Tolok | Ketebalan Nominal |
|---|---|
| 24 Tolok Keluli Tahan Karat | lebih kurang 0.6 mm (0.0239 inci) |
Namun begitu, the actual thickness may vary according to:
- ASTM tolerance standards
- Manufacturing process
- Cold rolling accuracy
- Surface finish type
- Gred bahan
2. Actual Thickness Tolerance Range
For cold rolled stainless steel sheets, thickness tolerance is generally controlled within a specified range.
Typical Actual Thickness Range for 24 Tolok Keluli Tahan Karat
| Ketebalan Nominal | Toleransi Biasa | Actual Thickness Range |
|---|---|---|
| 0.60 mm | ±0.03 mm to ±0.05 mm | 0.55 mm - 0.65 mm |
| 0.0239 inci | ±0.001–0.002 inch | 0.022–0.026 inch |
The exact tolerance depends on:
- International standards
- Production mill capability
- Sheet width and length
- Keperluan kemasan permukaan
3. Influence of Cold Rolling Process
24 gauge stainless steel is typically produced using cold rolling.
Characteristics of cold rolled stainless steel:
- Better thickness precision
- Improved surface smoothness
- More stable dimensional control
- Better flatness compared with hot rolled material
Because of the thin thickness, precision rolling control is especially important.
4. Thickness Difference by Stainless Steel Grade
Different stainless steel grades may have slight thickness variation due to rolling characteristics.
Common grades available in 24 tolok:
- 304 keluli tahan karat
- 304L keluli tahan karat
- 316 keluli tahan karat
- 430 keluli tahan karat
Austenitic grades such as 304 dan 316 generally maintain good thickness uniformity during cold rolling.
5. Why Actual Thickness Matters
Even small thickness variations can affect:
- CNC bending accuracy
- Welding performance
- Laser cutting settings
- Assembly fit-up
- Structural rigidity
- Weight calculations
Thin stainless steel sheets require accurate thickness control for precision fabrication.
6. Spesifikasi Lebar dan Panjang Biasa
24 gauge stainless steel sheet metal is commonly available in:
| Lebar | Panjang |
|---|---|
| 1000 mm | 2000 mm |
| 1219 mm | 2438 mm |
| 1500 mm | 3000 mm |
Custom cut sizes are also widely used in fabrication industries.
7. Processing Characteristics of 24 Tolok Keluli Tahan Karat
Because the material is relatively thin:
- Easy to bend and form
- Suitable for precision laser cutting
- Requires careful handling to prevent deformation
- Surface scratches are more visible
- Welding heat input must be controlled carefully
Kaedah pemprosesan biasa:
- Pemotongan laser
- lenturan CNC
- Kimpalan TIG
- Punching and perforation
- Penggilap permukaan
