Adinox Overseas is a prominent name in the stainless steel industry, offering a wide range of premium-grade Stainless Steel 321 Round Bars. Manufactured using top-quality raw materials and advanced technology, these round bars are engineered to perform under extreme environments. SS 321 is an austenitic stainless steel stabilized with titanium, which provides excellent resistance to intergranular corrosion even after exposure to temperatures in the chromium carbide precipitation range of 427°C to 816°C.
We supply ASTM A276 TP321 Round Bars and UNS S32100 Rods in various sizes, finishes, and lengths as per international standards. This alloy is well-suited for high-temperature service because of its good mechanical strength and oxidation resistance up to 900°C. These properties make it an ideal choice for heat exchangers, aircraft exhaust manifolds, furnace parts, and expansion joints. Our SS 321 round bars exhibit superior weldability and formability, which is especially beneficial in pressure vessel and heat treatment applications.
With exceptional quality control and adherence to global specifications, Adinox Overseas ensures that each Stainless Steel 321 Bar meets or exceeds industry standards. Our products comply with ASTM A276 and A479 specifications and are widely accepted across oil and gas, petrochemical, power generation, and marine industries. The addition of titanium in the 321 grade prevents carbide precipitation during welding, thereby increasing its stability and durability.
The UNS S32100 stainless steel round bars are known for their non-magnetic properties in the annealed condition, high tensile strength, and resistance to high-stress conditions. These bars also retain their strength and toughness even at sub-zero temperatures, making them a reliable material for cryogenic applications. The finish of our bars ranges from bright, black, rough turned, to polished, depending on client requirements.
