Overview|Specifications|Applications|Finish Options|How to Measure|Order Checklist

Type 304 is the most versatile austenitic stainless steel, containing 18% chromium and 8% nickel for superior resistance to corrosion in various environments. This bar is produced in an annealed condition, making it non-magnetic, highly ductile, and easily weldable by all common methods. Conforming to ASTM A276, it provides reliable mechanical properties for demanding structural and fabrication projects that require longevity and minimal maintenance.

As a large-format bar, the 6" width and 3/8" thickness make it exceptionally suited for applications requiring significant strength and surface area. Common uses include structural base plates for machinery, heavy-duty braces and gussets in construction, support frames for food processing equipment, and custom flanges where corrosion resistance is paramount.
