Isis Metals is a reputable manufacturer and supplier in Manila, Philippines, that produces top-quality SS 317 Hollow Bars that are renowned for delivering top-notch performance in diverse industries. These hollow bars provide excellent corrosion resistance, strength, and weldability, making them suitable for high-demanding conditions. Used in pharmaceutical, food processing, construction, and marine industries, SS 317 Hollow Bars can perform under demanding conditions. Their higher resistance against pitting, crevice corrosion, and heat guarantees long-lasting stability and dependability. At Isis Metals, we integrate superior manufacturing techniques and high quality control measures to ensure products that surpass the highest industrial and engineering standards.
SS 317 Hollow Bars consist mainly of iron, with major alloying components consisting of chromium (19–22%), nickel (11–15%), and molybdenum (3–4%) that increase resistance against corrosion and toughness. This alloy offers superior durability even in extremely aggressive conditions. Mechanically, SS 317 has a tensile strength of 550–750 MPa, yield strength of 215 MPa, and elongation of approximately 40%. These characteristics make it suitable for applications requiring high performance. It also shows superior formability, weldability, and resistance to pitting and crevice corrosion, providing assured performance in harsh temperature and chemical environments.

SS 317 Hollow Bars are commonly used in industries requiring high corrosion resistance, such as chemical processing, pharmaceuticals, food processing, and marine environments. They are ideal for manufacturing pipes, heat exchangers, pressure vessels, and other equipment exposed to harsh 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.
SS 317 Hollow Bars by Isis Metals are used by industries that require high corrosion resistance and higher strength. They are used in high frequencies by pharmaceutical and food processing industries, where reliability and hygiene are of prime importance. Their high chemical resistance and heat resistance make them perfect for use in chemical processing, power generation, and sea environments. Moreover, they find application in construction, heat exchangers, condensers, and other high-stress machinery that is exposed to harsh or corrosive conditions. With superior weldability and extended service life, SS 317 Hollow Bars offer reliable performance in severe industrial applications, with reliability and efficiency in all applications.
