Custom UNS S17400 Stainless Steel Forging Rings for Aerospace Applications

UNS S17400 precipitation-hardening stainless steel delivers exceptional corrosion resistance, mechanical performance, and heat-treatability. It features superior chloride stress corrosion cracking resistance, particularly in chloride environments. The alloy's composition (Fe-Cr-Ni-Cu-Mo base with controlled C/Nb additions) ensures stable performance in high-temperature and highly corrosive conditions.

• High Strength: Achieves ~1100 MPa tensile strength (H1150 condition: solution treatment + low-temperature aging)
• Corrosion Resistance: Exceeds standard stainless steels in aggressive chemical/climatic environments
• Heat Treatability: Tunable properties via solution treatment/aging for optimized strength/corrosion balance
• Surface Integrity: Maintains post-HT grindability for precision applications
• Weldability: Good performance with controlled heat treatment and proper welding procedures

Critical components in aerospace structural elements, petrochemical processing equipment, medical implant devices, and high-stress corrosion-resistant systems.
