Precision Slit 304 Stainless Steel Strip

Precision Slit 304 Stainless Steel Strip offers balanced corrosion resistance, formability, and weldability for industrial and commercial applications. Produced via cold-rolling and precision leveling, this material maintains strict dimensional consistency and controlled mechanical properties.

Each coil and sheet undergoes automated surface inspection and thickness profiling to eliminate camber, edge wave, and oil-canning defects. Available in standard and custom slit-to-width dimensions, it integrates directly into automated stamping, laser cutting, and deep-drawing lines.

Strict Thickness Control: Rolling tolerances maintained within +/- 0.015 mm to +/- 0.03 mm, ensuring consistent feed rates in progressive die stamping.

Controlled Mechanical Properties: Stable yield and tensile strength ratios prevent spring-back variance during bending and forming operations.

Uniform Surface Integrity: Defect-free finishes processed via tension-leveling lines, eliminating residual internal stresses.

Traceable Chemical Composition: Controlled carbon (C <= 0.08%), chromium (18% - 20%), and nickel (8% - 10.5%) content delivering reliable pitting resistance.

Complete Mill Test Reports: Every shipment includes EN 10204 3.1 certified MTRs verifying physical and chemical test results.

AISI 304 / 304L: Standard low-carbon variant available for enhanced intergranular corrosion resistance after welding.

Surface Finishes:

2B: Cold-rolled, annealed, pickled, and skin-passed for a smooth, matte finish.

BA (Bright Annealed): Controlled atmosphere furnace-annealed for a reflective, mirror-like appearance.

No. 4 / Hairline (HL): Directional polished finish for architectural and appliance applications.

PVC Coating: Optional single or double-side laser-safe PE film (50 um - 100 um) for scratch protection during fabrication.

Standard off-the-shelf sheets do not always match complex engineering requirements. Mill operations support custom processing parameters:

Precision Slitting: Narrow widths down to 10 mm with burr-free edges.

Cut-to-Length: Sheets sheared or laser-cut to exact dimensional drawings (+/- 0.2 mm).

Special Tempers: Quarter-hard (1/4H), half-hard (1/2H), and full-hard conditions available for applications requiring higher rigidity without heat treatment.

Product reliability relies on rigorous in-house testing protocols before dispatch:

Spectrometer Analysis: Direct-reading optical emission spectrometry verifies exact alloy composition per melt batch.

Tensile Testing: Universal testing machines measure yield strength, tensile strength, and elongation parameters.

Surface Defect Detection: Automated optical inspection (AOI) lines screen for pinholes, scratches, inclusions, and roller marks.

Flatness Measurement: Laser-based flatness scanners monitor crown and edge wave parameters to ensure sheet planarity.

Export-grade packaging protects metal integrity during transoceanic transit and multi-modal logistics:

Layer Protection: Interleaving paper or PVC film applied between sheets to prevent friction scratching.

Skid Configuration: Fumigation-free wooden pallets or heavy-duty steel skids with waterproof inner wrapping and desiccant bags.

Edge Protection: Corner protectors and steel strapping secure bundles to prevent shifting during container loading.
