3mm Harga Plat Keluli Tahan Karat
The difference between cold rolled and hot rolled 3mm plat keluli tahan karat directly affects both application and price.
- Cold rolled plates offer better surface quality and precision
- Hot rolled plates provide cost efficiency and structural strength
- Penerangan
3mm plat keluli tahan karat is a widely used thickness in industrial and architectural applications. It offers a balance between kekuatan, rintangan kakisan, dan kebolehkerjaan.
Apabila berbincang 3mm stainless steel plate price, one of the key influencing factors is the production process, mainly divided into:
- Cold rolled stainless steel plate (CR)
- Hot rolled stainless steel plate (HR)
These two types differ significantly in kualiti permukaan, sifat mekanikal, and application fields.
Cold Rolled 3mm Stainless Steel Plate
Manufacturing Characteristics
- Processed at room temperature after hot rolling
- Further rolling improves surface finish and dimensional accuracy
- Typically supplied with smooth finishes such as 2B, BA, atau cermin
Ciri-ciri Utama
- High surface quality and flatness
- Precise thickness tolerance
- Better appearance for decorative use
- Higher production cost compared to hot rolled
Aplikasi Biasa
1. Penggunaan Seni Bina dan Hiasan
- Panel lif
- Wall cladding and interior decoration
- Ceiling and facade panels
2. Precision Fabrication
- Peralatan dapur
- Jentera pemprosesan makanan
- Peralatan perubatan
3. Light Industrial Components
- Kandang dan kabinet
- Sheet metal fabrication parts
Cold rolled 3mm stainless steel plates are mainly used where surface quality and appearance are critical.
Hot Rolled 3mm Stainless Steel Plate
Manufacturing Characteristics
- Rolled at high temperature (above recrystallization temperature)
- Produced directly from slabs
- Surface is relatively rough, often requiring further processing
Ciri-ciri Utama
- Lower cost compared to cold rolled
- Kekuatan mekanikal yang baik
- Less strict dimensional tolerance
- Surface typically in No.1 finish
Aplikasi Biasa
1. Structural and Engineering Use
- Steel structures and frames
- Platform perindustrian
- Load-bearing components
2. Heavy Equipment Manufacturing
- Machinery parts
- Kapal tekanan
- Tangki simpanan
3. Fabrikasi Perindustrian
- Base plates and supports
- Welding structures
Hot rolled 3mm plates are preferred where strength and cost efficiency are more important than appearance.
Cold Rolled vs Hot Rolled – Comparison
| Ciri | Gulung Sejuk (CR) | Digulung Panas (HR) |
|---|---|---|
| Kemasan Permukaan | lancar, terang | Kasar, scaled |
| Thickness Accuracy | tinggi | Sederhana |
| kekuatan | Slightly higher due to work hardening | Good structural strength |
| kos | Lebih tinggi | Lebih rendah |
| Kegunaan Utama | hiasan, ketepatan | berstruktur, perindustrian |
Impact on Price
For 3mm stainless steel plates:
- Cold rolled plates → Higher price due to additional processing and better surface quality
