National India. Co (India) is one of the well-established Suppliers for SS 316 / 316L Flanges, which performs well in boiling 20 % phosphoric acid. Our Stainless Steel 316 Slip On Flanges can likewise be used in the food and pharmaceutical process sectors where it is used to deal with 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 cases, the corrosion resistance of our Stainless Steel 316 Weld Neck Flanges will be generally equivalent in most corrosive environments. In any cases, in environments that are adequately corrosive to cause intergranular corrosion of welds and heat – affected zones, these Stainless Steel UNS S31600 / S31603 Blind Flanges ought be utilized for the reason that of its low carbon content. Our Stainless Steel 316 Socket Weld Flanges can be effectively welded and handled by standard shop fabrication practices. Forming working temperatures of 1700 Degree F – 2200 Degree F (927 Degree – 1204 Degree C) are prescribed in these Stainless Steel 316L Lap Joint Flanges for most hot working procedures. Alloy Stainless Steel 316 Ring Joint Type Flanges is quite ductile and forms easily, which is liable to work hardening during deformation and is subject to chip breaking. Cold working activities will increase the strength and hardness of these Stainless Steel 316L Spectacle Blind Flanges and might abandon it slightly magnetic.
