Premium-grade stainless steel 317 bars designed for extremely corrosive and high-stress industrial settings are available from Vinit Stainless, a well-known manufacturer and supplier with headquarters in Chennai, India. Compared to standard 304 and 316 grades, SS 317, an austenitic stainless steel that contains molybdenum, exhibits superior corrosion resistance, particularly in environments that are acidic and chloride-rich. Vinit Stainless uses sophisticated equipment and stringent quality control to produce these bars in order to satisfy both client and international standards. Our SS 317 bars, which come in a variety of sizes and finishes, are perfect for the paper, chemical, petrochemical, and marine industries where dependability and durability are crucial.
18–20% chromium, 11–15% nickel, and 3–4% molybdenum make up stainless steel 317 bars. Manganese, silicon, and up to 0.08% carbon are also added. The resistance to pitting and crevice corrosion is greatly increased by the high molybdenum content. SS 317 bars normally have a yield strength of about 205 MPa and a tensile strength of 515–760 MPa. The alloy offers outstanding formability, weldability, and ductility. It works effectively in harsh chemical and mechanical environments, providing stability and resistance to corrosion in high-temperature and reducing media such as phosphoric and sulphuric acids.

Stainless Steel 317 T-Bars are typically available in sizes like 10mm x 10mm to 100mm x 100mm. These bars provide high resistance to corrosion and are used in structural supports and frameworks exposed to aggressive conditions.
Industries that need to withstand harsh chemicals, high pressure, and high temperatures frequently use stainless steel 317 bars. Equipment used in the food processing, textile dyeing, pulp and paper, and chemical processing industries are examples of common applications. These bars are perfect for piping systems, heat exchangers, tanks, and evaporators that are subjected to strong corrosive substances like phosphoric acid, sulphuric acid, and chlorides. They are also appropriate for pollution control systems and marine environments due to their exceptional resistance to oxidation and corrosion. Because of their mechanical strength and resistance to stress corrosion cracking, SS 317 bars are preferred in welded and fabricated structures.
