Lamiera spessa in acciaio inossidabile

Thick stainless steel sheets cover a wide range of specifications from medium plates around 3 mm to extra heavy plates above 100 spessore mm. These materials are widely used in heavy industrial and structural applications where strength, resistenza alla corrosione, and durability are required.

Common grades such as 304, 316, and duplex stainless steels are available in various thicknesses and dimensions, allowing stainless steel plates to meet diverse engineering and fabrication requirements.

Descrizione

Thick stainless steel sheet refers to medium and heavy gauge stainless steel plates used in structural engineering, attrezzature industriali, recipienti a pressione, costruzione navale, produzione di macchinari, and heavy fabrication industries. Compared with thin stainless steel sheets, thick plates provide higher strength, migliore capacità di carico, e una migliore stabilità strutturale.

The definition of “thick” stainless steel sheet varies by industry, but materials above approximately 3 mm thickness are generally classified as medium or thick stainless steel plates.

1. Common Thickness Range of Stainless Steel Sheets and Plates

Categoria	Intervallo di spessore	Applicazione tipica
Thin Stainless Steel Sheet	0.3 mm - 3 mm	Decorazione, attrezzatura da cucina, fabbricazione di precisione
Medium Thickness Plate	3 mm - 20 mm	Fabbricazione strutturale, serbatoi, macchinari
Thick Stainless Steel Plate	20 mm - 60 mm	Heavy industry, recipienti a pressione
Extra Thick Stainless Steel Plate	60 mm e oltre	Al largo, costruzione navale, heavy engineering

3. Specifiche comuni di larghezza e lunghezza

Thick stainless steel sheets are typically supplied in standard plate dimensions.

Larghezza	Lunghezza comune
1000 mm	2000 mm
1219 mm	2438 mm
1500 mm	3000 mm
1800 mm	6000 mm
2000 mm	6000 mm

Custom cutting and processing sizes are also common in industrial applications.

4. Hot Rolled vs Cold Rolled Thickness Range

Acciaio inossidabile laminato a freddo

Usually produced from 0.3 mm a 6 mm
Better surface finish and dimensional accuracy
Common surface finishes: 2B, BA, spazzolato

Acciaio inossidabile laminato a caldo

Commonly produced above 3 spessore mm
Suitable for heavy plates and structural applications
Typical surface finish: No.1 finish

Thicker stainless steel plates are generally manufactured using hot rolling processes.

5. Common Stainless Steel Grades for Thick Plates

Grado	Caratteristiche principali
304	Resistenza generale alla corrosione
304l	Migliore saldabilità
316	Improved chloride resistance
316l	Basso tenore di carbonio, chemical applications
310S	Resistenza alle alte temperature
2205 Duplex	Elevata robustezza e resistenza alla corrosione
