Al Summan Metals is a reliable manufacturer, supplier, and exporter of Stainless Steel 317 Hex Bars, recognized for their outstanding corrosion resistance, stress-to-rupture performance, and remarkable durability under high temperatures. SS 317 Hex Bars do not respond to heat treatment and gain increased strength through cold working. Stainless Steel 317 Hex Bars are widely used in handling sulfur compounds, corrosive dyestuffs, pulp liquors, acetylating and nitrating agents, petroleum and coal processing, bleaching solutions, and numerous other chemical mixtures. SS 317 Hex Bars represent a high-chromium, nickel, and molybdenum version of SS 316, developed mainly for greater strength and improved corrosion resistance.
SS 317 Hex Barsare made up of high chromium (18–20%), nickel (11–15%), and molybdenum (3–4%) content, and rods with balanced additions of manganese, silicon, and carbon. This composition guarantees outstanding corrosion resistance and durability. these bars provide a tensile strength of roughly 515 MPa and a yield strength of 205 MPa, along with an elongation of 40%. Their elevated melting point (1400–1450°C) and exceptional toughness make them well suited for demanding uses in the chemical and marine industries.

SS 321 hex bars/rods are exceptionally well-suited for high-temperature applications thanks to their outstanding resistance to oxidation and scaling, especially in environments exceeding 900°C. Titanium is added to stabilize the material, which prevents carbide precipitation and improves its resistance to intergranular corrosion, making it perfect for aerospace and industrial applications.
SS 321 hex bars/rods are frequently applied in sectors that demand high-temperature resistance, including aerospace, chemical processing, and power generation. Uses include exhaust systems, heat exchangers, furnace components, and reactors. Because they resist corrosion, oxidation, and scaling, they are well suited for settings with high temperatures and harsh conditions.
SS 321 hex bars/rods lend themselves to easy welding, though extra caution must be taken to avoid carbide precipitation. To prevent weld embrittlement, preheating and post-weld heat treatment are advised. Employing titanium-stabilized filler metals preserves the alloy's resistance to intergranular corrosion, safeguarding weld integrity in high-temperature applications.
SS 321 hex bars/rodsare widely employed in applications that demand strong resistance to heat and corrosion. Thanks to its resistance to oxidation and intergranular corrosion, it works well for uses in chemical processing, air space, and food processing These rods are found in heat exchangers, boilers and in the car’s interior. Because they withstand high temperatures, they suit environments involving heat cycles and aggressive chemicals, letting them endure longer and operate under tougher conditions, as well as being used in the construction of welded and internal pipe manufacture.
Our offerings include both mill test certificates and third-party test certificates, guaranteeing the highest levels of quality and compliance.
