Louis Metals, a reputable stainless steel manufacturer and supplier located in Houston, USA, proudly offers top-quality Stainless Steel 317L Round Bars and Rods. These products are renowned for their exceptional corrosion resistance and strength, especially in harsh chemical environments. SS 317L is a low-carbon, high-molybdenum austenitic stainless steel specifically engineered to combat pitting, crevice corrosion, and stress corrosion cracking in acidic and chloride-heavy conditions. Our 317L round bars and rods are meticulously crafted to meet the stringent demands of industries such as chemical, pharmaceutical, marine, and pulp & paper. At Louis Metals, we guarantee high-performance materials with a flawless finish, precise tolerances, and quick delivery for even the most challenging industrial applications.
Stainless Steel 317L Round Bars and Rods are composed of 18–20% chromium, 11–15% nickel, and 3–4% molybdenum, with a maximum carbon content of 0.03% to avoid sensitization during welding. This alloy boasts a tensile strength ranging from 515 to 760 MPa and a yield strength of approximately 205 MPa, along with impressive elongation and ductility. It excels in resisting chemical attacks, particularly from sulfurous, acetic, formic, and citric acids. Additionally, 317L performs admirably in high-chloride environments, providing superior corrosion resistance compared to 316L. Its low carbon content not only enhances weldability but also reduces the risk of intergranular corrosion after welding or exposure to heat.
