Stainless Steel 316L Flanges
Stainless Steel 316L Flanges Manufacturer and Supplier in India
Stainless Steel 316L Flanges are pipe connection elements manufactured from the low carbon austenitic stainless steel for leak-proof and reliable connections in piping systems exposed to corrosive environments. These flanges are made of ASTM A182 F316L material, and can be processed by accurate machining, dimensional inspection and heat treatment/forging to ensure the dimensional accuracy and function. Stainless steel 316L material has a minimum tensile strength of 485MPa and is highly resistant to chlorides, chemical and pitting corrosion. Lower carbon content of the 316L flanges makes them highly corrosion resistant, as there are no carbides formed when welded unlike other stainless steel flanges such as 304. Solitaire Overseas, known as the Stainless Steel 316L Flanges Manufacturer & Supplier in India, delivers premium quality flanges meeting international standards for use in the industries where toughness is an important factor.
