Titanium Palladium Hex Socket Head Cap Screws (Special Item)

About Titanium Palladium

It is a material in which palladium is added to pure titanium, and is also called corrosion-resistant titanium.
Titanium already has excellent corrosion resistance, but by adding palladium, a passive film that is stable even in reducing corrosive environments is formed, demonstrating even higher corrosion resistance.

Characteristics

  • The specific gravity is approximately 60% that of stainless steel.
  • Non-magnetic.
  • Excellent chemical resistance / seawater resistance.
  • Excellent nitrohydrochloric acid and crevice corrosion resistance.
