5mm 스테인레스 스틸 시트

5mm 스테인레스 스틸 시트

하지만 5mm 스테인레스 강판 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, 굽힘, and welding require stronger equipment and adjusted parameters, making 5mm stainless steel suitable for medium-to-heavy industrial applications requiring both strength and durability.

설명

mm 스테인레스 스틸 시트 is considered a medium-thickness stainless steel material widely used in machinery structures, 산업 장비, 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?

예, 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

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

Production Process of 5mm Stainless Steel Sheet

1. 열간압연 (Primary Forming)

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

2. 산 세척 및 표면 청소

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

3. Cold Rolling or Cold Finishing (선택 과목)

Improves surface smoothness
Enhances dimensional accuracy
Increases strength through work hardening

4. Annealing Treatment

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

5. 레벨링 및 교정

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

Processing Methods for 5mm Stainless Steel Sheet

얇은 시트에 비해, 5mm stainless steel requires stronger equipment and adjusted parameters.

1. 절단 공정

레이저 절단

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

플라즈마 절단

Faster for structural parts
Slightly rough edge compared to laser

워터젯 절단

열영향부 없음
Ideal for precision parts and thick sections

기계적 절단

Guillotine shearing possible but limited for complex shapes

2. 굽힘 및 성형

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

일반적인 용접 방법:

TIG 용접 (높은 정밀도)
미그 용접 (efficient for thicker plates)

Welding Characteristics:

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

4. 표면 처리

Available surface finishes:

2비 (cold rolled finish)
No.1 (hot rolled pickled surface)
브러시 마감 (4호, HL)
광택 또는 거울 마감 (after mechanical polishing)
