1. What is Alloy B3 Steel Plate?

Alloy B3(UNS N10675), or Hastelloy B-3, is a wrought nickel-molybdenum alloy developed by Haynes International, designed for superior corrosion resistance in reducing acids like hydrochloric and sulfuric acids. With improved thermal stability over Alloy C276, B3 material resists pitting and stress corrosion cracking, and its low carbon content enhances weldability, making Alloy B3 plate ideal for chemical reactors and piping systems.

How Does Alloy B3 Compare to Alloy C2000?

Alloy B3(UNS N10675) has higher molybdenum (28.5% vs. 15-17%) than Alloy C2000, offering better resistance to reducing acids like hydrochloric acid, while Alloy C2000 excels in mixed acid environments due to its copper content. Alloy B3 is preferred for applications requiring thermal stability during welding.
