3/4" 316/316L Stainless steel square bar

Product Overview

316/316L stainless steel square bar offers superior corrosion resistance, strength, and long-term durability for demanding environments such as marine construction, chemical processing, and heavy industrial use. As part of the austenitic stainless steel family, it contains molybdenum, giving it excellent performance in chloride-rich conditions like seawater, and superior resistance to pitting and crevice corrosion compared to 304 stainless steel.

Our offerings include standard 316 stainless steel square bar stock in a variety of sizes, as well as fully customizable 316 stainless steel square bar sizes to meet specific engineering or architectural requirements. Backed by years of metallurgical experience, our 316 stainless steel square bar factory ensures precision manufacturing, consistent mechanical properties, and global supply capacity. Whether you're looking for cut lengths, full bar stock, or export-ready bundles, we are your trusted stainless steel partner.

Key Properties

• Corrosion Resistance: Exceptional resistance to salt water, chlorides, acidic chemicals, and high-moisture environments. Perfect for coastal construction, chemical plants, and food processing.

• Strength & Durability: Higher tensile and yield strength compared to 304/304L, suitable for high-stress and load-bearing components.

• Non-Magnetic Nature: Ideal for electrical and sensitive environments where magnetic interference must be avoided.

• Weldability & Workability: Can be easily machined, bent, and welded using standard fabrication techniques. Ideal for both manual and automated assembly lines.

---

Manufacturing Process

• Forming: Produced using cold rolling for precision tolerances or hot pressing for heavy-duty bars, depending on your strength and dimensional needs.

• Heat Treatment: Annealed after forming to relieve internal stresses and ensure optimal mechanical performance. This also enhances its corrosion resistance in aggressive environments.

• Surface Processing: Choose from brushed matte, high-polish, or mirror finishes based on aesthetic or functional requirements. Polished surfaces are easier to clean, while brushed finishes offer subtle elegance for visible structural elements.
