Description
Hastelloy B2 Round Bars
Hastelloy B2 Round Bars is an corrosion resistant alloy (Nickel-Molydenum-mixed crystal) with an checked minimum content of iron and chrome excellent resistance against reducing substances, also against various organic acids good resistance against hydrochloric acid in a wide range of concentrations and temperatures
Hastelloy B2 Round Bar shows good resistance against corrosion due to tension and fissures due to a low carbon and silicium content (which lowers carbide secretion in heated areas of weld seams) this material shows sufficient resistance against corrosion even in a welded state.
Hastelloy B2 also known as Alloy B2 is Nickel Molybdenum Solution Hardened Alloy for increase strength at elevated temperatures. Having molybdenus as an alloying element, it provide excellent resistance to reducing agents & formation of grain boundry precipitating the carbide at heat affected zone.
Hastelloy® B2 is a grade of Hastelloy which is a nickel-molybdenum alloy. There are many different grades of Hastelloy, which includes B2. Grades of Hastelloy have each been optimized for a specific purpose. Molybdenum makes Hastelloy harder and stronger at high temperatures. This alloying element and the characteristics it imbues into the material also makes it great for welding applications. These nickel alloys are easily fabricated and formed. They also exhibit good ductility and are able to be cold worked.
All grades of Hastelloy are considered to be a corrosion resistant alloy because each grade exhibits superior resistance to various corrosive environments. Hastelloy has outstanding resistance to highly oxidizing corrosives such as oxidizing salts and reducing agents, making it a great alloy to specify for applications used in moderate to severe corrosive environments.
