Harsh Metalloys is a reputed manufacturer and supplier of Stainless Steel 317L Bars in Mumbai, India. Known for their outstanding corrosion resistance and excellent mechanical properties, these bars are widely used in demanding industrial applications. Made from low carbon, molybdenum-enriched austenitic stainless steel, our 317L bars comply with international standards such as ASTM A276 and ASTM A479. Available in various sizes and finishes, these bars are ideal for fabricating components that require high strength and durability in aggressive chemical environments, including chemical processing, marine, and pharmaceutical industries.
Stainless Steel 317L Bars feature a chemical composition with 17–20% chromium, 11–15% nickel, 3–4% molybdenum, and a maximum of 0.03% carbon. The low carbon content prevents carbide precipitation during welding, enhancing corrosion resistance in harsh environments. These bars have a typical tensile strength of around 515 MPa and a yield strength near 205 MPa, offering excellent ductility and toughness. Their molybdenum content significantly improves resistance to pitting and crevice corrosion, making them highly reliable for critical applications in acidic and chloride-rich atmospheres.
