Ferritic Structure, Magnetic Response & Surface Control
Grade 430 is a chromium ferritic stainless steel often selected for formed and finished components in mild-service environments.
Ferritic microstructure gives 430 a magnetic response at room temperature. Specify your grade and delivery condition where magnetism matters.
Chromium supports corrosion resistance in selected indoor and mildly corrosive duties. Include your actual exposure and cleaning conditions in the RFQ.
Select the finish, flatness and forming requirements alongside the dimensions. We will confirm the product form available for your order.
