317 round bars, a high-molybdenum austenitic stainless steel (UNS S31700), excel in resisting pitting, crevice corrosion, and stress corrosion cracking in aggressive media. With 3-4% molybdenum and increased chromium content, this alloy outperforms 316 in chloride-rich environments, making it suitable for seawater systems, pulp mills, and chemical processing. Newstar Hardware’s 317 round bars offer a minimum tensile strength of 515MPa and yield strength of 205MPa, with elongation over 40% for formability in machining and welding. Manufactured to ASTM A276 and A479, these bars come in diameters from 10mm to 200mm, with options for hot-rolled, cold-drawn, or annealed finishes. The alloy’s resistance to sulfuric acid (up to 50% concentration at room temperature) and chlorides (such as seawater) extends service life in offshore platforms, desalination plants, and wastewater treatment facilities. Its austenitic structure ensures non-magnetic properties, while high-temperature stability (up to 870°C) allows use in heat exchangers and furnace components. Rigorous testing for intergranular corrosion (ASTM A262 Practice E) guarantees reliability in critical applications.
