Short answer: 430 is a ferritic stainless steel with 16–18% chromium and no nickel. It is magnetic, lower cost than 304, and well suited for indoor decorative, appliance, and automotive trim applications where extreme corrosion resistance is not required.
At a Glance
What Is 430 Stainless Steel?
430 stainless steel is a straight-chromium ferritic grade. Unlike austenitic 304, it contains no nickel and is magnetic. It offers good corrosion resistance in mild environments and is one of the most cost-effective stainless grades.
Common standards include ASTM A240, EN 10088-2, and JIS G4305. 430 스테인리스 강판 and sheet are widely used in appliances, automotive trim, and decorative panels.
주요 속성
- Magnetic: Yes, 430 is strongly magnetic because of its ferritic structure.
- 내식성: Good in dry indoor atmospheres; less resistant than 304 in chloride or acidic conditions.
- Formability: Moderate; can be formed and drawn but less ductile than 304.
- Heat resistance: Good oxidation resistance up to about 815 °C, making it useful for some heat-resistant parts.
430 vs 304: Cost and Performance
430 is typically 20–30% less expensive than 304 because it contains no nickel. It is the better choice when the part will not see salt, bleach, or acidic exposure and when magnetic properties are acceptable or required.
Choose 304 when corrosion resistance, weldability, or non-magnetic properties are important. Choose 430 for decorative, indoor, and cost-sensitive applications.

자주 묻는 질문
Yes. 430 is a ferritic grade and is strongly magnetic. This makes it useful for magnetic fixtures, appliances, and applications where magnets must stick.
It resists rust in dry indoor environments, but it is less resistant than 304 in humid, salty, or acidic conditions. Regular cleaning helps maintain its appearance.
430 is usually 20–30% cheaper because it contains no nickel.
It can be used for some food-contact applications, but 304 is preferred for food equipment because of its better corrosion resistance and formability.
Appliance panels, automotive trim, indoor decorative panels, and cost-sensitive parts where moderate corrosion resistance is sufficient.
