Hemi Metals is a renowned manufacturer and exporter of Stainless Steel 304 Hex Bars/Rods, recognized for their enhanced resistance to water-based environments. The inclusion of molybdenum and copper in SS 304 Hexagon Bars improves their ability to withstand reducing agents and acidic conditions. Grade 304 Hex Bars are highly resistant to localized attacks such as pitting and crevice corrosion. Additionally, Type 304 Hex Bars exhibit exceptional protection against the buildup of oxidizing agents, including nitric acid, nitrates. Stainless Steel UNS S30400 Hex Bars have remarkable protection against acid reduction and oxidation, to propagate crumbling fractures, and limited attack, for example, setting, hole use, in conditions Constraint mix of Stainless Steel Name 1.4301 Hexagon Bars in normal restricted use provides wide availability
SS 304 Hex Bars/Rods are primarily steel, containing about 18-20% chromium and 8-10.5% nickel, along with small amounts of carbon, manganese, silicon and molybdenum for increased strength These bars have excellent mechanical properties a it has a tensile strength of 515 MPa for, of 205 MPa Also sacrificial yield strength, which ensures when hardened under compression they exhibit excellent ductility with 40% elongation at cryogenic temperatures and remarkable toughness. The material also has a Brinell hardness of approximately 201 HBW, ensuring corrosion resistance and suitability for harsh applications.

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.
SS 304 Hex Bars/Rods are widely used in applications requiring high strength, corrosion resistance and durability. Typical applications include manufacturing processes for food processing equipment, pharmaceuticals, pharmaceuticals and the marine environment. It is also used in construction for parts such as bolts, nuts, shafts, valves and fittings, and in the automotive and aerospace industries. In addition, SS 304 Hex Bars are ideal for construction applications such as gloves, accessories, and kitchen appliances. Their resistance to oxidation and acids makes them suitable for harsh environments and high temperature applications.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
