Al Summan Metals, a premier manufacturer and supplier based in Dubai, UAE, is renowned for its high-grade Stainless Steel 321H Hex Bars and Rods. Engineered to deliver exceptional resistance to intergranular corrosion and oxidation, particularly under high temperatures, these products are a dependable option for demanding industrial environments. Al Summan Metals employs advanced manufacturing techniques and stringent quality control to guarantee compliance with international standards. Offered in various sizes and finishes, these Stainless Steel 321H Hex Bars and Rods are ideal for sectors such as chemical processing, petrochemicals, aerospace, and power generation, delivering durability, structural integrity, and lasting performance even under extreme heat and corrosive conditions.
Stainless Steel 321H Hex Bars and Rods are made up of chromium (17–19%), nickel (9–12%), carbon (0.08–0.10%), together with manganese, silicon, and titanium, the latter of which serves to stabilize the alloy against carbide precipitation. These bars deliver a tensile strength of roughly 515 MPa, a yield strength of approximately 205 MPa, and an elongation of 40%. They provide outstanding mechanical stability, creep resistance, and oxidation resistance, which makes them well suited for prolonged use in high-temperature and corrosive settings without compromising strength or durability.

SS 321H Hex Bars/Rods offer strong resistance to oxidation and intergranular corrosion thanks to titanium stabilization, which makes them well suited for high-temperature settings. They deliver outstanding strength, durability, and resistance to sulfur compounds, guaranteeing dependability under extreme conditions.
SS 321H Hex Bars/Rods find frequent application across the aerospace, chemical processing, power generation, petrochemical, and pharmaceutical industries. Thanks to their outstanding corrosion resistance, they are well suited for high-temperature uses like heat exchangers, pressure vessels, exhaust systems, and furnace components.
SS 321H Hex Bars/Rods weld with ease, owing to their titanium stabilization, which guards against sensitization and intergranular corrosion. That said, using low-carbon filler materials is critical to preserve the material's properties and avoid carbide precipitation. Pre-heating and post-weld heat treatment might be needed for the best outcomes.
Stainless Steel 321H Hex Bars and Rods are widely employed in industries requiring heat resistance, corrosion protection, and mechanical reliability. They are ideal for manufacturing heat exchangers, furnace components, pressure vessels, boiler tubes, and exhaust systems. These bars are extensively used in chemical plants, petrochemical facilities, power generation equipment, and aerospace sectors where high-temperature stability and lasting durability are essential. Moreover, Stainless Steel 321H Hex Bars and Rods are also well-suited for the food processing and pharmaceutical industries, where hygiene, oxidation resistance, and structural integrity are critical for safe and efficient operations.
We supply products accompanied by both mill test certificates and third-party test certificates, guaranteeing the highest standards of quality and compliance.
