Aung Metals is a trusted manufacturer, supplier, and exporter of Stainless Steel 317 Hex Bars, renowned for their superior corrosion resistance, stress-to-rupture performance, and exceptional durability at elevated temperatures. SS 317 Hex Bars are non-responsive to heat treatment and achieve enhanced strength through cold working. Stainless Steel 317 Hex Bars find extensive applications in handling sulfur compounds, corrosive dyestuffs, pulp liquors, acetylating and nitrating agents, petroleum and coal processing, bleaching solutions, and various other chemical mixtures. SS 317 Hex Bars are a high-chromium, nickel, and molybdenum variant of SS 316, designed primarily for improved strength and enhanced corrosion resistance.
SS 317 Hex Bars and rods are composed of high chromium (18–20%), nickel (11–15%), and molybdenum (3–4%) content, with balanced additions of manganese, silicon, and carbon. This composition ensures excellent corrosion resistance and durability. these bars offer a tensile strength of approximately 515 MPa and a yield strength of 205 MPa, with an elongation of 40%. Their high melting point (1400–1450°C) and superior toughness make them ideal for demanding applications in chemical and marine industries.

SS 321 hex bars/rods are highly suitable for high-temperature applications due to their excellent resistance to oxidation and scaling, particularly in environments above 900°C. The addition of titanium stabilizes the material, preventing carbide precipitation, and enhancing its resistance to intergranular corrosion, making it ideal for aerospace and industrial applications.
SS 321 hex bars/rods are commonly used in industries requiring high-temperature resistance, such as aerospace, chemical processing, and power generation. Applications include exhaust systems, heat exchangers, furnace components, and reactors. Their resistance to corrosion, oxidation, and scaling makes them ideal for environments with elevated temperatures and aggressive conditions.
SS 321 hex bars/rods can be welded easily, but special care is needed to prevent carbide precipitation. Preheating and post-weld heat treatment are recommended to avoid weld embrittlement. Using titanium-stabilized filler metals helps maintain the alloy’s resistance to intergranular corrosion, ensuring weld integrity in high-temperature applications.
SS 321 hex bars/rods are commonly used in applications requiring high resistance to heat and corrosion. Due to its resistance to oxidation and intergranular corrosion, it is ideal for applications in chemical processing, air space, and food processing These rods are used in heat exchangers, boilers and in the car’s interior. Their resistance to high temperatures makes them suitable for environments where heat cycles and harsh chemicals are used, allowing them to last longer and work in harsher conditions in addition to being used in buildings of welded and internal pipe manufacture.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
