Nickel alloy B3 is a high-performance material meticulously designed to address the challenges of previous-generation B alloys. It offers superior resistance to general corrosion, pitting, crevice corrosion, and stress corrosion cracking in strongly reducing environments (particularly hydrochloric and sulfuric acids). Its optimized chemical composition significantly enhances thermal stability and post-weld intergranular corrosion resistance. This makes B3 an ideal choice for handling the most demanding corrosive media in the chemical, petrochemical, energy, and environmental protection sectors, ensuring longer equipment life and greater operational reliability. In applications requiring resistance to strong reducing acid corrosion, B3 is generally considered a more reliable and advanced alternative to B2.
Key considerations for selecting B3: It is primarily intended for applications operating in medium- to high-temperature environments with strong reducing acids (particularly HCl and H₂SO₄), where weldability, post-weld corrosion resistance, and long-term thermal stability are of particular concern.
