2. More information about Hastelloy B2 flange:
| Name | Hastelloy B2 Flange |
| Grade | Hastelloy |
| Featuers | Hastelloy B-2 has outstanding resistance to hydrochloric acid at all concentrations and temperatures. It also has significant resistance to reducing environments like sulfuric, phosphoric, acetic acids and other nonoxidizing media. Hastelloy B-2 has excellent resistance to pitting corrosion, stress corrosion cracking, and knife line and weld heat-affected zone attack. Hastelloy B-2 has poor resistance to oxidizing environments, therefore, it should not be used where ferric or cupric salts are present as these salts may cause rapid corrosion failure. |
| Application | Chemical processing involving acetic acid, acetic anhydride and complex acid mixture; pickling operations; cellophane manufacture; chlorination systems; electro-galvanizing rolls, expansion bellows; flue gas scrubber systems; geothermal wells; HF furnace scrubbers; incineration scrubbers; nuclear fuel reprocessing; pesticide production; phosphoric acid production; heat exchangers; selective leaching systems; sulfur dioxide cooling towers; sulphonation systems; and weld overlay. |
