Stainless Steel 321H Round Bar is a heat-resistant and corrosion-resistant alloy bar manufactured to standards like ASTM A276 / ASME SA276 / A479, ideal for high-temperature and engineering applications. Grade 321H (UNS S32109) stainless steel is an austenitic alloy stabilized with titanium, which prevents intergranular corrosion and enhances performance in thermal environments. The higher carbon content compared to standard 321 improves strength at elevated temperatures.
These round bars are available in a wide range of diameters (e.g., ~4 mm to 500 mm) and finishes such as black, bright, polished, matt, NO.4, and can be supplied in custom lengths with annealed or normalized condition. They deliver consistent mechanical strength, good ductility, excellent weldability, and resistance to oxidation and corrosive media.
Common applications include chemical processing equipment, petrochemical plants, oil & gas systems, power generation components, industrial machinery, and heat-exposed structural parts.
