Sachiya Steel International offers a wide range of Hastelloy C276 Flanges, which has some excellent features to offer such as dimensional accuracy, durable finish standards, corrosion resistant and more. The low carbon content in these Hastelloy C276 Threaded Flanges (UNS N10276) minimizes carbide precipitation during welding to maintain corrosion resistance in as – welded structures. Hastelloy C276 Slip On Flanges can be cold worked by all conventional methods.
These Hastelloy C276 Spectacle Blind Flanges withstands the corrosive effects of wet chlorine gas, hypochlorite and chlorine dioxide. Hastelloy C276 Weld Neck Flanges should be considered for use in environments where resistance to hot contaminated mineral acids, organic and inorganic chloride – contaminated media, chlorine, formic and acetic acids, acetic, acetic anhydride, sea water and brine solutions is desired. Meanwhile, these Hastelloy C276 Lap Joint Flanges are also being offered in customized sizes and shapes to our customers.
Similar properties of Hastelloy C276 Ring Joint Type Flanges are found in silicon – chromium steels, in chromium steels of high nickel – content, in chromium – tungsten steels, and in the high – chromium steels, the last mentioned being called stainless steel. When liquid quenching is impractical (because of the danger of cracking or distortion, or because of cost), various low – carbon nickel or nickel – molybdenum steels such as these Hastelloy C276 Socket Weld Flanges in the normalized – and – tempered condition can be used for low – temperature service.
