What is Hastelloy C

Hastelloy 100 is a nickel-based corrosion-resistant alloy, which is mainly divided into nickel-chromium alloy and nickel-chromium-molybdenum alloy. Hastelloy has good corrosion resistance and thermal stability, and is mostly used in aviation and chemical fields.

Hastelloy Machining sheet is suitable for all kinds of chemical industries containing oxidizing and reducing media. The higher molybdenum and chromium content makes the alloy resistant to chloride ion corrosion, and the tungsten element further improves the corrosion resistance. At the same time, C-276 Hastelloy tube is one of the only materials known to be resistant to corrosion by wet chlorine gas, hypochlorite and chlorine dioxide solutions. It is suitable for high concentration chloride salt solutions such as ferric chloride and chlorination Copper has significant corrosion resistance.

Hastelloy characteristics:

  1. In the two atmospheres of oxidation and reduction, it has excellent internal corrosion resistance to most corrosive media.
  2. It has excellent resistance to pitting corrosion, crevice corrosion and stress cracking corrosion.

Hastelloy alloy machining is mainly divided into three series of B, C, G, it is mainly used for iron-based Cr-Ni or Cr-Ni-Mo stainless steel, non-metallic materials and other strong corrosive media occasions can not be used.

HASTELLOY C-4 has better thermal stability, 650-1040 degrees Celsius has better toughness and corrosion resistance.

HASTELLOY C-22 has better uniform corrosion resistance in oxidizing media than C-4 and C-276, and excellent local corrosion resistance. HASTELLOY C-276 has good resistance to oxidizing and moderately reducing corrosion, and excellent stress resistance Corrosion ability. HASTELLOY C-2000 is the most comprehensive corrosion-resistant alloy with excellent resistance to uniform corrosion in both oxidizing and reducing environments.

HASTELLOY G-35 G-30 is an upgraded product with better corrosion resistance and thermal stability. HASTELLOY G-30 is a nickel-based alloy machining with high chromium content. It is excellent in phosphoric acid and other strong oxidizing mixed acid media.
