Product Overview
430 stainless steel square pipe offers excellent corrosion resistance, formability, and cost efficiency. As a ferritic stainless steel with 16-18% chromium and low nickel content, it provides a budget-friendly alternative to more expensive austenitic grades like 304 or 316. The square profile makes it especially popular for visible architectural applications, structural elements, and areas requiring both strength and a clean, modern aesthetic.
This type of stainless steel square pipe is particularly well-suited for use in automotive trim, kitchen equipment, commercial interiors, storage systems, and protective barriers. Its magnetic properties and moderate resistance to oxidation make it ideal for projects in indoor or mildly corrosive outdoor environments. We offer full customization for surface finishes, length, and wall thickness to meet specific engineering and design requirements.

Key Properties
-
Corrosion Resistance: High, especially in indoor and dry environments. Performs well in kitchens, bathrooms, and semi-sheltered areas.
-
Heat Resistance: Can withstand up to 815°C (intermittent use), suitable for exhaust systems or heated enclosures.
-
Formability: Excellent bendability and weldability, making it suitable for a variety of fabrication processes.
-
Magnetism: The ferritic nature of 430 makes it magnetic, which is ideal for cabinet doors, appliances, and industrial shelving.
-
Surface Aesthetics: Available in brushed, polished, or mirror finishes, great for visible installations.
Manufacturing Process
-
Forming: Each 430 stainless steel square pipe is cold-rolled for superior dimensional accuracy, straightness, and a smoother surface.
-
Welding: Seamless or near-seamless welds are achieved using TIG or laser welding methods, resulting in high-strength joints with minimal distortion.
-
Treatment: Pipes are annealed post-forming to relieve stress, reduce brittleness, and enhance ductility. For projects requiring higher strength, cold-worked versions are available.
