Type 304 stainless steel is the most common austenitic chromium-nickel alloy, valued for its exceptional durability and resistance to a wide range of corrosive environments. Supplied in an annealed condition, it is non-magnetic and combines excellent ductility and formability with good mechanical properties. Conforming to ASTM A276, this grade is easily welded using all standard fusion methods, making it a reliable choice for fabricated assemblies.

As a large 4-inch wide bar, this product provides substantial surface area and structural integrity. It is an excellent choice for base plates for columns and machinery, heavy-duty structural supports, gussets, and components for industrial dies and fixtures where rigidity and corrosion resistance are paramount.
