1 1/2" 430 Stainless steel square bar

Product Overview

430 Stainless Steel Square Bar offers excellent corrosion resistance, formability, and cost efficiency, making it a popular choice across a wide range of industries. As a ferritic stainless steel, it contains 16–18% chromium, delivering good corrosion performance in mildly corrosive environments. It is particularly well-suited for applications that do not require the high strength or extreme corrosion resistance of austenitic grades like 304 or 316.

Our 430 Stainless Steel Square Bar is ideal for both structural and decorative purposes. It is frequently used in automotive trim, architectural accents, kitchen fixtures, and framing systems. Available in various surface finishes, including annealed, brushed, or polished, it can be tailored to suit both functional and aesthetic needs.

We maintain a wide inventory of stainless steel square bar stock, ready for immediate shipment to global markets. Whether you need half-inch square bar sizes like 50x50mm or custom-cut dimensions, we provide solutions that meet your precise requirements.

Key Properties

  • Corrosion Resistance: The chromium content in 430 Stainless Steel Square Bar provides solid resistance against oxidation, moisture, and mild chemicals, making it suitable for both indoor and dry outdoor use.

  • Strength: With a yield strength suitable for structural and light-load-bearing applications, this material performs well under mechanical stress.

  • Workability: Easily weldable and formable using standard fabrication methods. It can be bent, machined, or cut without extensive preparation.

  • Magnetic Response: Slightly magnetic in nature, which is a key identifier of ferritic stainless grades like 430.

Manufacturing Process

  • Forming: Our 430 Stainless Steel Square Bar is precision-formed using cold rolling techniques, ensuring dimensional consistency and a clean surface profile.

  • Heat Treatment: The bars are annealed to relieve internal stress, increase ductility, and enhance ease of machining.

  • Surface Processing: Finishing options such as brushing and polishing are applied to improve surface quality and appearance, especially important in visible or decorative applications.
