Hastelloy B3 alloy, UNS N10675, is made specifically to withstand extremely hostile hydrochloric acid (HCl), hydrobromic acid (HBr), sulfuric acid (H2SO4), as well as acetic, formic, and phosphoric acids. Hastelloy B3 also has greater structural integrity than B2 and is more corrosion resistant. Hastelloy B3 Flanges shouldn’t be used with oxidising media when there are salts present since it contains a small amount of chromium.
Strong resistance to knife-line and heat-affected zone assault exists in Hastelloy B3 Threaded Flanges (UNS N10675). When compared to B-2 alloy, Hastelloy B3 Slip On Flanges have improved thermal stability because of the unique chemistry that makes production simpler. Blind flanges made of Hastelloy B3 that are optically clear exhibit good oxidation and creep resistance. Because these salts can result in premature failure, it is not advised to use Hastelloy B3 Weld Neck Flanges in the presence of ferric or cupric salts. Hastelloy B3 Lap Joint Flanges have unique chemistry created to attain a level of thermal stability far above that of its predecessors, such as B2 alloy.
These B3 Flanges are incredibly high corrosion-resistant flanges intended for applications in a variety of acidic conditions. In comparison to other alloy flanges of comparable composition, these flanges have increased structural stability. They may therefore be made and welded with ease. Due to their ductility and resistance to stress corrosion cracking in high-chloride solutions, these B3 Flanges are a good choice. Additionally, they can survive sulfuric acid concentrations and other fluoride-bearing environments. These B3 Flanges provide great thermal stability in addition to having good corrosion and pitting resistance. Even after being exposed to temperatures in the middle, they are known to keep their ductility.
The Hastelloy B-3 alloy is a great choice for producing components when using cold-working processes. The instantaneous hardening of alloy B3 material during cold working necessitates additional cold working and annealing processes. The stress corrosion cracking resistance of alloy B3 can be further diminished by cold working.
Applications of Hastelloy B3 Flanges
These B3 Flanges are trustworthy for use in a variety of reducing conditions that contain pure hydrochloric, hydro-bromic, and sulfuric acids. Additionally, they are very resistant to non-oxidizing media like phosphoric, acetic, and formic acids. In piping systems in non-oxidizing settings, these B3 Flanges are frequently used. Chemical manufacture, speciality chemical, and gas processing are a few of the industries that use These B3 Flanges in their applications. In addition, they are employed in the production of herbicides and insecticides in several sectors. The industries that are engaged in producing ethylene glycol, ethylbenzene, and high-octane gasoline are home to some of the other applications.
