Precision Stainless Steel Sheet
Product Overview
Precision stainless steel sheet is cold-rolled to tight thickness tolerances, controlled flatness, and specific mechanical tempers. Designed for precision stamping, photo-chemical etching, laser cutting, and deep drawing, it maintains uniform dimensional stability and consistent metallurgical properties across the entire coil length and width. This minimizes downstream tooling wear, stamping springback variations, and production downtime.
Precision Thickness Control: Rolling tolerances maintained down to ±0.005 mm to ±0.01 mm based on specific gauges.
Tailored Tempers: Controlled mechanical states from fully annealed (soft) to 1/2H, 3/4H, and Full Hard (HV 150 to HV 550+).
Flatness & Low Stress: Multi-roller tension leveling eliminates coil set, edge camber, and internal residual stresses.
Clean Edge Specifications: Precision slit edges with tightly controlled burr height (guaranteed < 5% of material thickness).
Full Metallurgical Traceability: Tracked from melt shop to final slitting with distinct heat numbers.

Available Grades and Material Options
Austenitic Grades
AISI 304 / 304L: Balanced corrosion resistance, excellent cold formability, and superior weldability.
AISI 316 / 316L: Enhanced pitting and crevice corrosion resistance due to Molybdenum (Mo) alloying, suited for marine and chemical processing parts.
AISI 301: High work-hardening rate; achieves high tensile strength and spring properties after cold rolling.
Ferritic & Martensitic Grades
AISI 430: Cost-effective ferritic stainless steel with stable oxidation resistance at elevated operating temperatures.
AISI 420 / 440C: Hardenable grades utilized for precision blades, scrapers, and wear-resistant components.
Applications
New Energy Vehicles (NEVs)
Lithium-ion battery prismatic/cylindrical cell cases, current collectors, and battery pack explosion-proof safety valves.
Electronics & Telecommunications
Electromagnetic Interference (EMI) shielding cans, micro-connector spring contacts, and heat dissipation fins.
Medical & Healthcare
Surgical blades, lancet substrates, and diagnostic equipment internal shims.
Industrial Engineering

Custom Thickness and Dimensions
In addition to standard stock items in climate-controlled warehouses, in-house processing capabilities include:
Precision Slitting
Slitting narrow widths down to 5 mm with controlled straightness and minimum camber.
Blanking & Cut-to-Length
Flattening and shearing coils into precision sheets.
Surface Protection
Application of laser-safe or deep-drawing temporary PVC films (50 μm - 100 μm) upon request.
Manufacturing and processing follow rigid industrial quality protocols:
Real-time Dimensional Monitoring: Continuous online X-ray thickness measurement gauges during cold rolling.
Mechanical Testing: Lot-by-lot tensile strength, yield strength, elongation, and Vickers/Rockwell hardness testing.
Surface Defect Scanning: Optical surface inspection systems to detect pinholes, scratches, inclusions, and rolling oil stains.
Roughness Verification: Ra value checks via stylus profilometers to ensure coating and etching uniformity.
Packaging and Shipping
Engineered to withstand ocean freight and multi-modal transit without moisture or handling damage:
Inner Protection
Interleaved with neutral VCI (Volatile Corrosion Inhibitor) paper or sealed in moisture-barrier vacuum bags with desiccant.
Cushioning & Pallets
Securely mounted on fumigated wooden pallets or heavy-duty steel skeleton crates.
Edge Protection
Edge protectors and steel strapping to prevent transit collision and deformation.
