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

Type 304 is the most widely used austenitic chromium-nickel stainless steel, valued for its combination of strength, ductility, and corrosion resistance. Supplied in an annealed condition, it is non-magnetic and complies with ASTM A276 standards. Its balanced composition, often dual-certified as 304/304L for enhanced weldability, ensures reliable performance across a wide range of industrial and architectural applications.

As a medium-width 3" x 1/4" flat bar, this product is perfectly sized for manufacturing structural bracing, machine ways, wear strips, and support brackets. Its substantial width provides stability for base plates and gussets, while its thickness is suitable for general fabrication where both strength and formability are required.
