Corrosion Testing Excellent corrosion resistance to integranular corrosion. Good mechanical characteristics aligned with high corrosione resistance.
The main applications are for details with special requirements for high corrosion resistance. UNS S32760 is characterized by:
• High resistance to stress corrosion cracking in halide containing environments.
• High resistance to pitting and crevice corrosion.
• High resistance to general corrosion.
• High mechanical strength.
• High resistance to erosion corrosion and corrosion fatigue.
Very good
