Introduction: Why Slitting Line Stainless Steel Is Different

Unlike mild steel & galvanized coil, stainless steel coils are:

• Harder & stronger
• More sensitive to surface scratches
• More expensive per ton

That's why processing them - especially slitting - requires more precision, better tension control, and surface protection systems.

 

 

What Is a Stainless Steel Slitting Line?

A stainless steel coil slitting line is a processing system that uncoils, slits and rewinds stainless steel coils into narrow coils with exact dimensions.

 

The key parts include:

• Decoiler
• Pinch roller + leveler
• Slitter
• Scrap winder
• Tension station
• Recoiler
• Optional: Film laminator; paper collector

Kinbenz machine supprt standard coil widths up to 1600mm, thickness from 0.3-3.0mm, and high line speed up to 220m/min.

 

 

Key Applications Across Industries

 

Industry	Application Examples
Home Appliances	Stainless steel back panels, casings
Automotive	Interior trim, exhaust parts, brackets
Construction	Roofing strips, decorative panels
Kitchenware	Sink raw material, stainless utensils
Energy	Solar frame materials, mounting hardware

 

 

Benefits of Using a Stainless Steel Slitting Line

 

Precision Tolerance

Cut to ±0.2mm for tight coil width requirements

 

Surface Protection

Film laminator protects mirror/satin finishes from scratches during processing

 

Burr Control

Well-aligned blade shaft and proper clearance reduce burr height and rework

 

Reduced Downtime

Auto tension & scrap winding system ensures clean operation without manual trimming

 

 

Stainless Steel Grades Commonly Processed

 

Grade	Property	Common Use
304	Corrosion-resistant, general purpose	Appliances, construction
316	Marine-grade, chemical resistant	Food & pharma, coastal structures
430	Ferritic, low cost	Kitchenware, back panels
201	High manganese, cost-effective	Consumer goods, decorative items

FQA:

Q: What makes slitting stainless steel harder that slitting carbon steel?

A: Stainless steel has higher tensile strength and work hardness easily, requiring stronger blades and more precise clearance.

 

Q: How do you prevent scratches on stainless steel coils during slitting?

Use felt tension pads, film laminators, and anti-friction conveyor rollers. 

 

Q: How many strips can be slit at once?

It depends on coil width and strip width. As 1250mm coil width, can slit 8-20 strips of stainless steel.

 

 

Stainless steel slitting requires more than just speed - it demands finese. With its high value, surface sensitivity, and application in critical industries, a dedicated stainless steel slitting line can protect your investment and deliver reliable, accurate results.
