1. What is Alloy 400?

Alloy 400(UNS N04400), or Monel 400, is a wrought nickel-copper alloy developed by the International Nickel Company, known for its resistance to seawater, acids, and alkalis. With high strength and toughness, Alloy 400 material resists stress corrosion cracking and pitting, making Alloy 400 plate ideal for marine and chemical applications. Its single-phase solid-solution structure ensures good weldability, outperforming Alloy 625 in marine environments.

How Does Alloy 400 Compare to Alloy K500?

Alloy 400(UNS N04400) offers excellent corrosion resistance in marine environments, while Alloy K500 provides higher strength due to age-hardening but is less resistant to certain acids. Both are weldable, but Alloy 400 is preferred for general corrosion resistance.
