1/4" 904L Stainless steel square bar

Product Overview

904L stainless steel square bar delivers unparalleled corrosion resistance, high strength, and excellent mechanical durability, even in the most demanding industrial conditions. Engineered for environments where standard stainless steel grades like 304 or 316 fall short, 904L stainless steel square bar is the preferred material for applications involving aggressive chemicals, high humidity, and elevated temperatures.

Thanks to its low carbon content and high alloy composition (including nickel, molybdenum, and copper), this material is extremely resistant to strong reducing acids such as sulfuric acid and environments with high chloride levels, like marine and offshore installations. We offer a wide range of dimensions including the in-demand 10mm stainless steel square bar, along with custom size manufacturing options.

Whether you are sourcing materials for a chemical plant, desalination project, power generation facility, or high-temperature manufacturing system, our stainless steel square bar stock is available for quick shipment and meets the highest international quality standards.

Key Properties

• Corrosion Resistance: With high levels of chromium, nickel, molybdenum, and copper, 904L stainless steel square bar exhibits exceptional resistance to sulfuric acid, phosphoric acid, and seawater corrosion. It’s the top choice in chemical processing plants and coastal infrastructure.

• Mechanical Strength: Offers superior tensile and yield strength compared to standard stainless grades like 304 and 316. Ideal for heavy-duty structures, load-bearing systems, and high-pressure environments.

• Weight Efficiency: The strength-to-weight ratio of 904L allows designers to reduce material usage while maintaining structural integrity, helping to cut costs without compromising safety.

• Thermal Stability: Performs well in both cryogenic and high-heat applications. It maintains strength and corrosion resistance up to 550°C, suitable for heat exchangers, furnaces, and pressure vessels.

Manufacturing Process

• Forming: The bars are precision cold-drawn to achieve accurate square cross-sections with excellent straightness and surface finish.

• Heat Treatment: All 904L stainless steel square bar products are solution annealed to relieve stress and enhance corrosion resistance, especially in chloride-heavy environments.

• Surface Processing: Available in multiple surface finishes. Polished bars are suited for decorative or exposed environments, while brushed finishes are preferred in industrial settings for their non-reflective appearance and improved grip.
