followed by ASTM F899, specification for wrought stainless steels for surgical instruments
Stainless UNS S46500 alloy was designed to have excellent notch tensile strength and fracture
toughness in this condition.
Overaging to the H1000 condition provides a superior combination of strength, toughness,
and stress-corrosion cracking resistance compared with other high-strength precipitation hardenable
stainless alloys such as Custom 455 or 17-4PH.
Characteristics
- High tensile strength and toughness
- H950 condition, ulitimate tensile strength 1724Mpa
- H1000 condition, the toughness increased, aimed to improve the alloy's combination work performance
- Excellent corrosion resistance
The general corrosion resistance of Custom 465 approaches that of 304 stainless.
Exposure to 5% neutral salt spray at 95°F (35°C) (per ASTM B117) caused little or no rusting after 200 hours
regardless of condition (i.e., annealed or H950, H1100 conditions).
Double-cantilever-beam tests conducted in 3.5% NaCI (pH 6) show Custom 465 to possess inherently good
resistance to stress corrosion cracking that improves with increasing aging temperature.
Applications
