Lembaran Baja Tahan Karat Tebal

Thick stainless steel sheets cover a wide range of specifications from medium plates around 3 mm to extra heavy plates above 100 ketebalan mm. These materials are widely used in heavy industrial and structural applications where strength, ketahanan terhadap korosi, 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.

Keterangan

Thick stainless steel sheet refers to medium and heavy gauge stainless steel plates used in structural engineering, peralatan industri, bejana tekan, pembuatan kapal, manufaktur mesin, and heavy fabrication industries. Compared with thin stainless steel sheets, thick plates provide higher strength, kapasitas menahan beban yang lebih baik, dan meningkatkan stabilitas struktural.

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

Kategori	Kisaran Ketebalan	Aplikasi Khas
Thin Stainless Steel Sheet	0.3 mm – 3 mm	Dekorasi, perlengkapan dapur, fabrikasi presisi
Medium Thickness Plate	3 mm – 20 mm	Fabrikasi struktural, tank, mesin
Thick Stainless Steel Plate	20 mm – 60 mm	Heavy industry, bejana tekan
Extra Thick Stainless Steel Plate	60 mm ke atas	Di lepas pantai, pembuatan kapal, heavy engineering

4. Hot Rolled vs Cold Rolled Thickness Range

Baja Tahan Karat Canai Dingin

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

Baja Tahan Karat Canai Panas

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

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