Stainless Steel 310S Flanges
Stainless Steel 310S Flanges Manufacturer and Supplier in India
The Stainless Steel 310S Flanges are high chromium, high nickel austenitic steel flanges used for high temperature and corrosive service applications. These flanges are manufactured in accordance to ASTM A182 F310S requirements and provide excellent oxidation resistance up to 1100°C with intermittent service and good mechanical strength at high temperatures. They come in Weld Neck, Slip-On, Blind, Socket Weld, Threaded, Lap Joint and RTJ types and are used in heat treatment equipment, furnaces, petrochemical plants and chemical processing systems etc. The 310S low carbon content allows for better weldability and reduces carbide precipitation in the production process. These flanges also offer excellent toughness, ease of machining and resistance to scaling in challenging applications. Solitaire Overseas is a leading manufacturer and supplier of stainless steel 310s flanges in India, providing precision engineered flanges with different sizes, pressure class and specification, which are capable of delivering reliable performance and meet international quality standards.
