5mm Lembaran Keluli Tahan Karat

5mm Lembaran Keluli Tahan Karat

Walaupun 5kepingan keluli tahan karat mm is relatively thick, it can still be processed using a combination of hot rolling and cold finishing techniques. Cold rolling at this thickness is mainly used for improving surface quality and dimensional precision rather than primary thickness reduction. Processing methods such as cutting, membengkok, and welding require stronger equipment and adjusted parameters, making 5mm stainless steel suitable for medium-to-heavy industrial applications requiring both strength and durability.

Penerangan

mm Lembaran Keluli Tahan Karat is considered a medium-thickness stainless steel material widely used in machinery structures, peralatan industri, support frames, and engineering fabrication. Although 5mm thickness is relatively thick for cold-rolled stainless steel, it can still be produced and processed through specialized cold rolling and finishing techniques.

Can Cold Rolled Stainless Steel Be Used for Medium Thickness Plates?

ya, but with limitations.

Cold rolling is typically used for thin sheets, but when producing medium-thickness stainless steel (such as 5mm), manufacturers often combine:

Hot rolling for primary thickness reduction
Cold rolling for surface finishing and dimensional accuracy

Oleh itu, 5mm stainless steel sheets are often hot-rolled base material with cold-finished surface treatment.

Production Process of 5mm Stainless Steel Sheet

1. Bergolek Panas (Primary Forming)

Steel slabs are heated above recrystallization temperature
Thickness is reduced through rolling mills
Produces basic 5mm plate structure

2. Pickling and Surface Cleaning

Removes oxide scale formed during hot rolling
Improves surface quality before further processing

3. Cold Rolling or Cold Finishing (Pilihan)

Meningkatkan kelicinan permukaan
Enhances dimensional accuracy
Meningkatkan kekuatan melalui pengerasan kerja

4. Annealing Treatment

Restores ductility after cold working
Improves internal stress distribution
Ensures stable mechanical properties

5. Meratakan dan Meluruskan

Ensures flatness of medium-thickness sheets
Removes deformation caused during rolling

Processing Methods for 5mm Stainless Steel Sheet

Berbanding dengan kepingan nipis, 5mm stainless steel requires stronger equipment and adjusted parameters.

1. Proses Pemotongan

Pemotongan Laser

High power required for 5mm thickness
Clean edge quality
Suitable for complex shapes

Pemotongan Plasma

Faster for structural parts
Slightly rough edge compared to laser

Pemotongan Waterjet

Tiada zon terjejas haba
Ideal for precision parts and thick sections

Pemotongan Mekanikal

Guillotine shearing possible but limited for complex shapes

2. Membengkok dan Membentuk

5mm stainless steel sheet requires:

High-tonnage press brake machines
Larger bending radius compared to thin sheets
Controlled bending speed to avoid cracking

Key Points:

Thicker material = higher bending force
Minimum bend radius increases with thickness
Tool wear is higher than thin sheet processing

3. Welding Process

Kaedah kimpalan biasa:

Kimpalan TIG (ketepatan tinggi)
kimpalan MIG (efficient for thicker plates)

Welding Characteristics:

Requires higher heat input
Preheating may be needed in some cases
Strong joint strength after proper welding

4. Rawatan Permukaan

Available surface finishes:

2B (cold rolled finish)
No.1 (hot rolled pickled surface)
Kemasan berus (No.4, HL)
Polished or mirror finish (after mechanical polishing)
