Product Description
430 Stainless Steel Coil — Precision Slitting & Custom Width
When standard coil widths do not meet your downstream processing requirements, our precision slitting service delivers 430 stainless steel coil in any width from 20mm to 1500mm with tight tolerances and burr-free edges. CNC-controlled carbide slitting lines ensure consistent quality across every slit coil.
Precision Slitting Capabilities
- Width Range: 20mm - 1500mm — From ultra-narrow 20mm strips for electronic components to 1500mm full-width coils for large panel stamping. Any intermediate width available.
- Tight Tolerance: ±0.05mm Width — CNC-controlled slitting with carbide circular blades ensures width tolerance within ±0.05mm and burr height below 0.03mm.
- Flexible Coil ID Options: Standard 508mm/610mm ID plus 300mm compact ID for narrow strips. Custom coil weight from 0.5 ton to 8 tons per coil.
- Multi-Strand Slitting: Simultaneous multi-strand slitting up to 30 strips from a single master coil. Maximum material yield with minimal waste.

Industries & Applications
- Electronics & Precision Components: Narrow 20-100mm strips for connectors, springs, shielding covers, and battery tabs. Consistent thickness across narrow width prevents die wear.
- Automotive Stampings: 100-500mm strips for exhaust flanges, heat shields, decorative trim, and seat belt components. Tight width tolerance eliminates edge trimming operations.
- Kitchenware Manufacturing: 300-600mm slit coils for sink bowls, cutlery blanks, and cookware rims. Ready-to-feed width for progressive stamping dies.
- Metal Stamping & Roll Forming: Customer-specified widths eliminate in-house slitting, reducing labor cost and material waste in high-volume production.
- Ducting & HVAC: 100-400mm strips for spiral duct fabrication, with consistent flatness across the slit width.
Quality Assurance in Slitting
Every slit coil undergoes 3-point width measurement (head, middle, tail) per strand. CNC tension control prevents camber and edge wave during the slitting process. For gauges above 1.5mm, a secondary deburring pass is applied. Third-party SGS inspection reports available upon request for critical tolerance applications.
