Duplex Stainless Steel

Duplex Stainless Steel investment castings for industrial applications.

Duplex stainless steel castings for high strength and corrosion resistance

Duplex Stainless Steel

Duplex stainless steels combine the beneficial properties of both austenitic and ferritic phases, resulting in higher strength and better corrosion resistance than standard austenitic grades. They are particularly suited for chloride-containing environments, seawater, and chemical processing.

  • 2x strength of austenitic grades
  • Superior chloride stress corrosion cracking resistance
  • Excellent erosion-corrosion resistance
  • Good weldability with proper procedures
  • Operating temperature: -50°C to 300°C
Duplex grades for seawater, desalination, and chloride service
