Aditya Stainless stands out as a leading manufacturer and supplier of Stainless Steel 317 Bars, proudly based in Kolkata, India. SS 317 is a high-alloy austenitic stainless steel that’s rich in molybdenum, giving it remarkable resistance to chemical attacks and pitting, especially in chloride-rich environments. These bars are celebrated for their impressive strength, excellent formability, and superior corrosion resistance compared to more common stainless steels like 304 or 316. Offered in various shapes—round, hex, square, and flat—our SS 317 bars meet global standards such as ASTM A276, A479, and ASME SA276, making them perfect for tough industrial applications that face aggressive chemicals and high temperatures.
Stainless Steel 317 Bars are made up of chromium (18–20%), nickel (11–15%), molybdenum (3–4%), with minimal carbon content (≤0.08%), along with trace amounts of manganese and silicon. These bars boast a tensile strength of around 515 MPa, a yield strength of 205 MPa, and an elongation of about 35%. The added molybdenum enhances their resistance to pitting and crevice corrosion, ensuring they remain durable even in challenging environments. SS 317 not only offers excellent mechanical properties but also retains its structural integrity under high temperatures and acidic conditions.
