Ninthore Overseas is one of the Leading Manufacturer And Exporter Stainless Steel 316 Flanges, which performs well in boiling 20 % phosphoric acid. Our Stainless Steel 316 Slip On Flanges can also be used in the food and pharmaceutical process industries where it is utilized to handle hot organic and fatty acids in an effort to minimize product contamination. These Stainless Steel 316L Threaded Flanges performs well in fresh water service even with high levels of chlorides. In most instances, the corrosion resistance of our Stainless Steel 316 Weld Neck Flanges will be roughly equal in most corrosive environments.

However, in environments that are sufficiently corrosive to cause intergranular corrosion of welds and heat – affected zones, these Stainless Steel UNS S31600 / S31603 Blind Flanges should be used for the reason that of its low carbon content. Our Stainless Steel 316 Socket Weld Flanges can be easily welded and processed by standard shop fabrication practices. Forming working temperatures of 1700 Degree F – 2200 Degree F (927 Degree – 1204 Degree C) are recommended in these Stainless Steel 316L Lap Joint Flanges for most hot working processes.

Our Stainless Steel 316 Ring Joint Type Flanges is quite ductile and forms easily, which is subject to work hardening during deformation and is subject to chip breaking. Cold working operations will increase the strength and hardness of these Stainless Steel 316L Spectacle Blind Flanges and might leave it slightly magnetic.
