Product Overview –Hastelloy B2 Pipes
Hastelloy B2 Pipes, are high-performance nickel-molybdenum alloy pipes specially engineered for highly corrosive reducing environments. With excellent resistance to hydrochloric acid across a wide range of concentrations and temperatures, Hastelloy B2 is one of the preferred materials for chemical processing equipment handling aggressive reducing chemicals. The alloy also provides outstanding protection against sulfuric acid, phosphoric acid, acetic acid, and other non-oxidizing media, making it suitable for demanding industrial process systems.
Unlike many conventional stainless steels and nickel alloys, Hastelloy B2 offers exceptional resistance to pitting, stress corrosion cracking, and localized corrosion in reducing conditions. However, it is generally not recommended for strongly oxidizing environments because such media can affect the alloy's corrosion performance. When used in its intended service conditions, Hastelloy B2 delivers outstanding durability, reliability, and long operational life.
