Hastelloy is a series of materials, high temperature and corrosion resistance, nickel-based alloy .
The main grades are Hastelloy C-276, Hastelloy C22 , Hastelloy C-4, Hastelloy C-2000, Hastelloy B-2, Hastelloy B-2, Hastelloy G-30 and so on.
The most commonly used Hastelloy C276 pipe is introduced below.
Hastelloy C-276 Hastelloy, nickel-chromium-molybdenum alloy, high temperature and corrosion resistance.
Overview of Hastelloy C-276 Characteristics and Applications:The alloy has excellent corrosion resistance to most corrosive media in both oxidized and reduced states. Excellent resistance to pitting corrosion, crevice corrosion and stress corrosion cracking. The alloy is suitable for a variety of chemical process industries containing oxidizing and reducing media. The high molybdenum and chromium content makes the alloy resistant to chloride ions, and the tungsten element further enhances its corrosion resistance.Hastelloy C-276 is one of only a few materials resistant to corrosion by moist chlorine, hypochlorite, and chlorine dioxide solutions, and the alloy exhibits significant corrosion resistance to high concentrations of chlorinated salts (e.g., ferric and copper chlorides).Hastelloy C-276 is also a very good corrosion resistant alloy. 276 similar grades: W.Nr.2.4819?NiMo16Cr15W?(Germany)?NC17D?(France)

Hastelloy C-276?Metallurgical organization: the alloy is for the face-centered cubic Lattice structure. Hastelloy C-276 process performance and requirements: 1, the lower the sulfur content in the hot processing fuel the better, the sulfur content in natural gas should be less than 0.1%, the sulfur content in heavy oil should be less than 0.5%. 2, the alloy's hot processing temperature range of 1200 ℃ ~ 950 ℃, the cooling mode of water-cooled or fast air-cooled. 3, suitable for welding using any conventional welding process, such as tungsten Electrode inert gas shielded welding, plasma arc welding, manual sub arc welding, metal pole inert gas shielded welding, fusion pole inert gas shielded welding.
