Produced by vacuum induction melting and consumable vacuum arc re-melting, R30035 contains 35% nickel, 35% cobalt, 20% chromium, and 10% molybdenum. Strengthened by work hardening and aging to levels of 260 to 300 ksi (1790 to 2070 MPa), R30035 has good ductility with greater than 40% reduction in area, and good toughness. R30035 can be effectively utilized at cryogenic temperatures without embrittlement and up to 600°F without loss in performance.
The high strength and corrosion resistance, high modulus, ease of fabrication, and other mechanical properties make R30035 an ideal candidate for high performance products,
Typical applications:
- Orthodontic and Prosthetic devices
- Oil & Gas Industry, Chemical and Marine equipment – Valve components, springs, high pressure door dogs
- Aircraft and Aerospace components – Springs, leading edge strips
- High Pulse Magnet Research
