Chung Metal distributes corrosion-proof Stainless Steel 317L Square Bars and Rods, a low-carbon, high-molybdenum austenitic stainless steel alloy intended to have outstanding resistance to chemical attack and pitting in chloride and acid environments. SS 317L is extensively employed in aggressive chemical processing, marine, and pollution control applications. The square shape provides rigidity and equal strength, which is suitable for structural components, frames, and custom-machined pieces. Chung Metal offers 317L bars with exceptional dimensional accuracy and a range of surface finishes to satisfy critical demands in high-performance applications.
SS 317L has a composition of 18–20% chromium, 11–15% nickel, 3–4% molybdenum, and ≤0.03% carbon. It delivers tensile strength between 480–700 MPa, yield strength of 170–300 MPa, and elongation of 35–45%. Non-magnetic, weldable, and resistant to corrosion, it suits acidic and chloride environments. Mechanical stability in structural use is improved with the square profile.
