Serving clients around the globe, Semih Metals blends cutting-edge manufacturing techniques with dependable customer service, making them a go-to choice for industries that demand high-performance materials for tough applications, from chemical processing to marine environments.
Stainless Steel 317 Hollow Bars boast a robust composition of chromium, nickel, and molybdenum, which significantly boosts their resistance to corrosion, especially in chloride and acidic conditions. Their typical makeup includes about 18–20% chromium, 12–15% nickel, 3–4% molybdenum, and low carbon content to enhance weldability. On the mechanical side, these bars deliver impressive tensile strength, yield strength, and ductility, maintaining stability even at high temperatures. These characteristics make them highly resistant to pitting, crevice corrosion, and stress corrosion cracking. The hollow bar design strikes a balance between strength and reduced weight, ensuring efficient material usage while preserving structural integrity, making them perfect for high-stress and corrosive environments.

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.
Stainless Steel 317 Hollow Bars find extensive applications in the chemical and petrochemical sectors, food processing equipment, marine uses, and pharmaceutical manufacturing. Their outstanding corrosion resistance guarantees long-lasting performance in acidic and chloride-heavy environments. These hollow bars are also favored in scenarios where weight reduction is crucial without sacrificing strength, such as in fluid handling systems, shafts, and structural components. Additionally, they are utilized in heat exchangers and desalination plants, showcasing their versatility across various industries.
We provide products that come with both mill test certificates and third-party test certificates, ensuring the highest standards of quality and compliance.
