Aung Metals is a prominent manufacturer, trader, and exporter of Stainless Steel 317L Hex Bars and rods, known for their enhanced creep resistance, stress-to-rupture strength, and tensile strength at elevated temperatures. SS 317 Hex Bars remain unaffected by heat treatment and can be further strengthened through cold working. Stainless Steel 317L Hex Bars are widely used in applications involving sulfur, acid dyestuffs, pulp liquor, acetylating and nitrating mixtures, as well as harsh environments such as coal, oil, and bleaching solutions, and various chemical compounds. SS 317 Hex Bars offer superior corrosion resistance and strength, being a higher chromium, nickel, and molybdenum version of SS 316. However, it is important to note that SS 317L Hex Bars are vulnerable to corrosion when exposed to hydrochloric acid concentrations above 5%. For welding, low-carbon austenitic filler metals with a higher molybdenum content than Alloy 317 Hex Bars, or a nickel-based filler metal with sufficient chromium and molybdenum, should be used to ensure corrosion resistance.
Stainless Steel 317L Hex Bars/Rods are composed primarily of 18-20% chromium, 11-15% nickel, and 3-4% molybdenum, with trace amounts of carbon, silicon, manganese, and phosphorus. This composition provides enhanced resistance to corrosion and high strength at elevated temperatures. Mechanical properties include a tensile strength of 620 MPa, yield strength of 290 MPa, and elongation of 40% in 50 mm. The material exhibits excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, making it ideal for harsh environments, including chemical processing and marine applications.

SS 317L Hex Bars/Rods are commonly used in chemical processing, marine environments, pharmaceuticals, and food processing due to their excellent corrosion resistance and high strength. They are ideal for handling aggressive chemicals, including sulfuric acid, bleaching solutions, and pulp liquor. In construction, they are used for structural components and fittings.
SS 317L Hex Bars/Rods typically range from 6 mm to 100 mm in diameter, with lengths up to 6 meters. Tolerances generally conform to ±0.5 mm for diameter. These dimensions and tolerances ensure precision for machining, making them ideal for applications requiring high strength, corrosion resistance, and tight fit.
The high chromium (18-20%) and molybdenum (3-4%) content in SS 317L enhances its resistance to pitting and crevice corrosion by forming a passive oxide layer that protects against chloride-induced degradation. The low carbon content further reduces the risk of stress corrosion cracking, ensuring durability in harsh chloride environments.
SS 317L hex bars/rods are commonly used in applications requiring high corrosion resistance and durability. Due to their low carbon content they offer high weldability and strength, making them ideal for chemical processing, marine and medical applications and are commonly used in the manufacture of fasteners, valves, pumps and fittings. Their resistance to pitting, crack corrosion and high temperatures make the SS 317L hexbar suitable for harsh environments, including acidic and chloride-rich conditions, ensuring durability and reliability at in an important role.
