21 Alloys offers a wide range of Nickel Alloy 200 Flanges, which has some excellent quality of features such as fine finish, durable, dimensionally stable, and more. Nickel 200 Slip On Flanges (UNS N02200) offer corrosion resistance in reducing and neutral media as well as in oxidizing atmospheres provided that the oxidizing media allows the formation of a passive oxide film. Because the alloy displays good corrosion resistance, Nickel 200 Threaded Flanges has been used in food handling equipment, caustic solution, and general corrosion-resistant parts and structures. Nickel 200 Weld Neck Flanges has a low annealed hardness and very low work – hardening rate that is desirable for cold forming operations such as deep drawing, spinning, coining, etc. Meanwhile, these Nickel 200 Blind Flanges are also being offered in different sizes and shapes to our customers. Nickel 200 Socket Weld Flanges brings a new dimension to the well-known versatility of Ni – Cr – Mo alloys in resisting corrosion under widely varying conditions. Nickel 200 Lap Joint Flanges combines outstanding resistance to oxidizing media with superior resistance to reducing environments. Nickel 200 Ring Joint Type Flanges has pitting and crevice corrosion resistance superior to other alloys and resistance to H2SO4 up to 65 %. Nickel 200 Spectacle Blind Flanges resist all acids (especially hydrochloric, sulfuric, and hydrofluoric) over large temperature ranges. Nickel 200 Nippo Flanges also resist the insidious types of attack induced by chlorides and other halide solutions, specifically pitting, crevice attack, and stress corrosion cracking.
