With the increasing demand for SUS430 stainless steel foil from industries such as electronics, automotive exhaust systems, kitchen appliances, gaskets, and heat-resistant components, it has become one of the most sought-after materials in the stainless steel market. If you are looking for readily available SUS430 stainless steel foil, GNEE offers a full range of thin-gauge ferritic 430 stainless steel foil with stable supply, quality certification, and highly competitive pricing.
Our 430 stainless steel foil features a magnetic ferritic structure, exhibiting excellent corrosion resistance in mildly corrosive environments, intermittently up to 815°C. It also boasts good dimensional stability, is suitable for deep drawing and stamping, and is ideal for food-grade equipment, decorative parts, heaters, and kitchen appliances, all at a lower cost than 304/316 stainless steel.

Is SUS430 stainless steel foil rust-proof?
Under dry or mildly corrosive environments, SUS430 shows strong corrosion resistance. Not recommended for marine or high-chloride environments (304/316 preferred).
What is the difference between SUS430 foil and 304 foil?
The main differences are that 304 foil has superior corrosion resistance and toughness due to its nickel content, while 430 foil is less expensive and more magnetic, making it suitable for applications where cost is a factor and high corrosion resistance is not critical, such as kitchen appliances and decorative trim. Grade 430 is a ferritic stainless steel, whereas 304 is an austenitic stainless steel, meaning 304 is more stable and has stronger toughness.
