Stainless Steel 317L Flanges
Stainless Steel 317L Flanges Manufacturer and Supplier in India
Stainless steel 317L flanges are a high alloy austenitic stainless steel material composed of chromium, molybdenum and carbon, which have high resistance to corrosion, crevice corrosion and pitting corrosion, and resistant to harsh chemical environment. The flanges are produced to various international grades (ASTM A182 F317) and several different types including Weld Neck, Slip-On, Blind, Socket Weld and Threaded. The quality and material are kept consistent with the minimum tensile strength at 515 MPa and minimum yield strength at 205 MPa, for various industries. On the other hand, 317L has a higher molybdenum content than Stainless Steel 316L Flanges and can be used in more corrosive chemical and chloride-rich environments. Solitaire Overseas is a top stainless steel 317l flanges manufacturer and supplier in India, offering precision-engineered flanges that meet international quality and dimensional standards.

Frequently Asked Questions
Stainless Steel 317L Flanges offer excellent corrosion resistance, high strength, and reliable performance in aggressive chemical environments.
317L contains higher molybdenum content than 316L, providing improved resistance to pitting and crevice corrosion.
Yes, 317L Flanges have excellent resistance to chloride-induced corrosion and are suitable for harsh environments.
Yes, they perform well in many acidic and chemical processing applications due to their enhanced corrosion resistance.
Stainless Steel 317L typically contains approximately 3% to 4% molybdenum, which helps improve corrosion resistance.
SS 317L has a lower carbon content (0.030% max vs 0.08% max for 317), which improves weldability and reduces the risk of sensitisation and intergranular corrosion in welded assemblies.
