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.

The Stainless Steel 316L Round Bar (UNS S31603) is a premium-quality low-carbon austenitic stainless steel bar engineered for superior corrosion resistance, weldability, and durability in demanding industrial and marine environments. Manufactured in compliance with international standards and available in multiple diameters, lengths, and surface finishes (including black, bright, and polished), the 316L round bar delivers reliable performance for both structural and precision applications.

Duplex 2304 Stainless Steel Round Bar is a lean duplex stainless steel bar supplied under standards like ASTM A276 / A479 and ASME SA276 / SA479, with the designation UNS S32304 (EN 1.4362, DIN X2CrNiN23-4). It combines balanced ferritic-austenitic microstructure that delivers a high strength, corrosion-resistant, and cost-efficient alternative to conventional austenitic grades like 304L and 316L.
