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 conducts through an aluminum diffusion layer into the stainless steel 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.
Key Features
Magnetic Response: Ferritic microstructure provides the magnetic permeability required for induction hob heating
Bonding Reliability: Clean, uniform surface ensures 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 distribute heat evenly across pan bases and eliminate hot spots
Traceable Supply: Baosteel or TISCO base coils with full Mill Test Certificate and batch traceability

Applications
This magnetic 430 coil serves as the standard material for induction-compatible cookware bases, including frypans, woks, saucepans, milk pans, griddle plates, roasting trays, casserole dishes, and induction pressure cooker bottoms. It is also utilized by cookware blanking suppliers who provide pre-punched magnetic discs to original equipment manufacturers. Additionally, this grade is suitable for magnetic heating plates in electric kettles, rice cookers, coffee percolators, and catering warming trays where ferromagnetic elements must efficiently and safely convert induction energy into heat over extended service periods.
Packaging & Quality Assurance
Coils are delivered with anti-rust oil protection, waterproof kraft wrapping, plastic film, and steel strapping on fumigated wooden pallets ready for sea freight. Documentation includes the Mill Test Certificate, magnetic permeability test report, and dimensional inspection sheet. The manufacturing facility operates under ISO 9001:2015 certification, and independent inspection by SGS or other third-party agencies can be arranged upon request. Our technical team provides guidance on disc blanking dimensions, bonding process parameters, and surface preparation to help cookware plants achieve consistent induction performance in every production batch.
