Stainless Steel 317 Hollow Bar is a high-molybdenum austenitic stainless steel that’s alloyed with chromium and nickel, providing enhanced protection against pitting and crevice corrosion. Its higher molybdenum content, compared to 316, boosts strength and performance in chloride-rich settings. This alloy showcases impressive tensile and yield strength, along with excellent ductility and toughness across a wide temperature range. It also offers good weldability, formability, and resistance to oxidation, making it ideal for challenging fabrication and service conditions.

SS 317 offers superior corrosion resistance compared to standard stainless steels like SS 304 and SS 316, especially in chloride-rich environments. It provides enhanced protection against pitting, crevice corrosion, and general corrosion, making it ideal for harsh chemical and marine applications.
SS 317 Hollow Bars typically contain 18-20% chromium, 3-4% molybdenum, 13-15% nickel, with small amounts of manganese, silicon, and carbon. This composition provides excellent corrosion resistance, particularly against chlorides, and enhances its strength at high temperatures.
These Stainless Steel 317 Hollow Bars find extensive use in applications where top-notch corrosion resistance and mechanical strength are crucial. Common applications include chemical processing equipment, heat exchangers, condensers, pressure vessels, and piping systems that handle corrosive fluids. They are widely utilized in industries such as oil and gas, petrochemical, marine, pulp and paper, and offshore sectors. Moreover, these hollow bars are also perfect for pharmaceutical and food processing equipment, ensuring a long service life, structural integrity, and lower maintenance costs.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
