Hastelloy B Nickel base alloy

Extremely low silicon content of carbon, nickel molybdenum alloy Hastelloy B, reduces the welding heat affected zone of precipitation of carbon and other impurity phases, so the weld also has anti corrosive enough. Hastelloy B alloy has good corrosion resistance in reducing media, such as a variety of temperature and concentration of hydrochloric acid solution. In sulfuric acid medium concentration (or contain a certain amount of chloride ion) also has the advantages of corrosion resistance is very good. At the same time, can also be used for acetic acid and phosphoric acid environment. Alloy materials are only in metallographic suitable and pure crystal structure has the best corrosion resistance.
Hastelloy B Nickel alloy similar material are : UNS N10001
Hastelloy B Nickel alloy application :
Alloy Hastelloy B is widely used in the field of energy production and pollution control, chemical, petrochemical, especially in the sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid industry.
