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.

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.
Kinbenz's stainless slitting line is trusted by global clients for custom design, strong engineering, and full after-sales support.
