Chuck Metals is a reputable manufacturer and supplier of Stainless Steel 304 Hex Bars and Rods right here in Singapore, serving a variety of industrial sectors across Pulau Ujong. Stainless Steel 304 is a popular austenitic alloy celebrated for its outstanding corrosion resistance, formability, and mechanical properties, making it a go-to choice for both structural and precision applications. Crafted in accordance with ASTM A276 and other relevant standards, our 304 hex bars and rods deliver excellent machinability, weldability, and durability, even in challenging working environments.
The alloy composition features 18–20% chromium and 8–10.5% nickel, which together provide robust resistance to oxidation, chemical exposure, and mild acidic conditions. With a tensile strength of about 515 MPa and a yield strength of roughly 205 MPa, Stainless Steel 304 hex bars are perfect for medium-load applications that experience moderate thermal conditions.

Standard sizes for SS 304 hex bars/rods typically range from 1/8" to 6" in diameter. Custom sizes, lengths, and finishes are generally available upon request, depending on the supplier's capabilities and production methods.
SS 304 hex bars/rods can be welded and fabricated into complex shapes with relative ease. It offers good weldability, but pre-welding surface preparation and proper techniques are necessary to avoid distortion or degradation of material properties.
SS 304 offers good strength and corrosion resistance, suitable for many applications. Compared to other grades like SS 316, it has slightly lower corrosion resistance, especially in chloride environments, but SS 304 is more cost-effective and widely used.
These hexagonal bars and rods find their way into the production of fasteners, valve stems, machine parts, automotive components, and architectural fixtures. Their precise shape and reliable performance make Stainless Steel 304 hex bars an excellent choice for both functional and aesthetic needs in manufacturing and construction.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
