Technical Specification Matrix

Why 430 is the Strategic Choice for Your Project?

Stable Cost Efficiency (Nickel-Free): As a ferritic grade with 0% Nickel, 430 offers high price stability compared to the 300 series. It is the premier choice for high-volume production without sacrificing surface quality.
Superior Thermal Conductivity: 430 has better thermal conductivity than 304, making it ideal for heat exchangers, household appliance heating elements, and kitchenware.
Magnetic Functionality: Unlike 304/316, 430 is magnetic. This is essential for induction-compatible cookware, magnetic sensors, and electronic shielding components.
Exceptional Polishability (BA Finish): 430 is famous for achieving a deep, "blue-tone" mirror finish (BA), which is highly valued in automotive trim and decorative moldings.

Advanced In-House Processing Capabilities

Ultra-Narrow Slitting: Our factory specializes in precision slitting down to 3mm in width. We ensure zero-burr edges, crucial for high-speed automated stamping and fine-wire applications.
Surface Consistency: Our BA (Bright Annealed) coils undergo strict atmosphere-controlled annealing to ensure a clean, bright, and scale-free surface that requires no further polishing.
Visual Transparency: We provide HD "immersive" videos for every batch. You can witness the surface texture and gauge measurement as if you were in our Wuxi facility.

Global Compliance & B2B Service

Documentation: Fully traceable MTR (Mill Test Report) provided with every shipment. Compliance with EN 10204 3.1, ASTM A240, and JIS G4305.
Packaging: Export-grade reinforced packaging (Eye to Sky/Eye to Wall) with multi-layer moisture protection for long-distance maritime shipping.
Inspection: Cooperative with third-party inspection agencies (SGS, TUV, BV) to verify chemical composition and mechanical properties.
