- Excellent Corrosion Resistance & Weldability
Type 304 stainless steel, also known as 18-8, is the most common austenitic chromium-nickel alloy, valued for its ductility, weldability, and corrosion resistance in a wide range of industrial and domestic environments. This flat bar, produced in an annealed condition to ASTM A276 standards, is non-magnetic and maintains its mechanical properties across a wide temperature range, making it a reliable material for fabrication.
As a large 6-inch wide flat bar, this product excels in applications requiring broad, stable surfaces and structural integrity. It is frequently specified for base plates for heavy machinery, structural gussets and braces in construction, wear strips, and support components in food processing equipment where both strength and cleanliness are essential.
