21 Alloys is one of the well-established exporter and trading house of quality Nickel Alloy 201 Flanges, which is used as a catalyst for hydrogenating vegetable oils. These Nickel 201 Slip On Flanges is found naturally in both food and water, and may be increased by human pollution. Nickel – plated faucets such as Nickel 201 Threaded Flanges may contaminate water and soil; mining and smelting may dump nickel into waste – water; nickel – steel alloy cookware and nickel – pigmented dishes may release nickel into food. A less – common form of chronic exposure in these Nickel 201 Weld Neck Flanges is through haemodialysis as traces of nickel ions may be absorbed into the plasma from the chelating action of albumin. Nickel 201 Blind Flanges resists corrosion and is used to plate other metals to protect them. These Nickel 201 Socket Weld Flanges cannot be avoided completely and is, however, mainly used in making alloys such as stainless steel. 

Nickel 201 Lap Joint Flanges is an alloy of nickel and chromium with small amounts of silicon, manganese and iron. These Nickel 201 Ring Joint Type Flanges resists corrosion, even when red hot, so is used in toasters and electric ovens. Nickel 201 Spectacle Blind Flanges is commonly used in desalination plants, which convert seawater into fresh water. These Nickel 201 Nippo Flanges is used for armour plating, and also in boat propeller shafts and turbine blades.
