Product Description
Induction Cookware Grade 430 Stainless Steel Coil
This magnetic ferritic stainless steel coil is specifically manufactured for the bonded bottom layer of induction-compatible cookware. The 430 ferritic stainless steel's magnetic properties allow discs punched from this coil to respond to induction hob alternating magnetic fields, generating heat that transfers through an aluminum diffusion layer to the cooking surface above. Cookware manufacturers utilize this grade to produce induction-ready frypans, saucepans, stockpots, griddles, and roasting pans while maintaining cost efficiency compared to clad austenitic solutions.
The coil is cold-rolled to precise gauge specifications with clean 2B or BA surfaces that ensure reliable bonding to aluminum impact-bonded or clad bases. Consistent hardness across coils guarantees identical deep-drawing behavior during concave pan bottom formation, while the low carbon ferritic chemistry minimizes delamination risk during high-pressure bonding processes. Each heat is traceable to Baosteel or TISCO base material and accompanied by a Mill Test Certificate confirming magnetic permeability, chemical composition, and mechanical properties required by kitchenware quality systems.
Key Features
- Magnetic Response: Ferritic microstructure provides the magnetic permeability required for induction hob heating
- Bonding Reliability: Clean and uniform surface guarantees strong adhesion to aluminum diffusion layers under high-pressure cladding
- Precise Gauge: Thickness tolerance of ±0.02mm supports consistent disc weight and flat bottom geometry
- Deep Drawing Stability: Annealed structure allows concave forming of pan bottoms without thinning or tearing
- Food Safe Chemistry: Chromium-rich passive layer delivers corrosion resistance for daily kitchen contact and dishwasher exposure
- Thermal Conductivity Support: Works with aluminum cores to spread heat evenly across the pan base and eliminate hot spots
- Traceable Supply: Baosteel or TISCO base coils with full Mill Test Certificate and batch traceability
