Hart b.v. is a stockholder and supplier of Alloy 625 products:

  • Pipe (seamless and welded in random lengths and cut to size)
  • Fittings (BW and forged fittings)
  • Flanges (ANSI, DIN, EN, JIS)
  • Bar (round, square and hexagonal in random lengths and cut to size)

Applications Alloy 625:
Alloy 625 is a nickel-chromium-molybdenum alloy with niobium added. This provides high strength without a strengthening heat treatment. The alloy resists a wide range of severely corrosive environments and is especially resistant to pitting and crevice corrosion. Used in chemical processing, aerospace and marine engineering, pollution-control equipment, and nuclear reactors.
