BÖHLER N701AMS
BÖHLER N701 AMS is a premium, aerospace-quality corrosion-resistant steel available in bars, wire, and forgings with diameters/thicknesses up to 203 mm in the solution-annealed condition, as well as pre-forging stock of any size.
It is a martensitic, precipitation-hardenable chromium-nickel-copper steel with high strength and toughness. Further strength increases can be achieved through cold working and subsequent precipitation hardening.
These products are typically used for parts requiring corrosion resistance and high strength up to 316 °C and must exhibit good transverse toughness and strength in large dimensions. However, their use is not limited to such applications.
Certain processing methods and operating conditions can make these products susceptible to stress corrosion cracking.
