Nickel 200 / 201 Pipe Fittings & Flanges

Commercially pure Nickel 200 contains excellent mechanical properties as well as exceptional corrosion resistance to corrosives, specifically hydroxides. In addition to the resistance to the corrosion in acids and alkalis, Nickel 200 also comprises notable electrical, thermal and magneto-strictive properties. It is most convenient to use under reducing conditions.
Alloy 200 offers good corrosion resistance to reducing and neutral environments. However, corrosion resistance is considerably low I marine and rural medias. Nickel alloy 200 can only be used in temperature lower than 600° F, at temperatures higher than 600° F alloy 200 products can experience graphitization which may result in affecting other important characteristics.

Properties of Nickel 200.
• Great resistance to most reducing chemicals
• Good resistance to caustic alkalies
• Exceptional corrosion resistance to distilled and natural water
• Ability to oppose neutral and alkaline salt solutions
• Good immunity to dry fluorine
• Satisfactory thermal, electrical and magnetostrictive properties
• Provides resistance to hydrochloric and sulfuric acids in normal temperatures

Just like alloy 200, Nickel 201 is commercially wrought Nickel with similar characteristics but has lower concentration of carbon. This is to resist embrittlement (which is the loss of ductility of a material making it brittle), by inter-powdered carbon at raised temperature.
Alloy 201 comes with the ability to resist reducing and neutral atmospheres. Also, due to the presence of nickel content, corrosion resistance by distilled and natural water is superb.

Properties of Nickel 201
• Corrosion resistant in acids and alkalis and highly useful in reducing conditions.
• Nickel 201 resists caustic alkalies to a great level until the molten state is reached.
• Resistance is notable in acid, alkaline and neutral salt solutions. However, in oxidizing salt solutions severe attacks will occur.
