BÖHLER N700

BÖHLER N700 is a high-quality corrosion-resistant steel in aerospace quality, in the form of bars, wire and forgings with a diameter/thickness of up to 203 mm in the solution-annealed condition, as well as starting material of any size for forging purposes.
It is a martensitic, precipitation-hardenable chromium-nickel-copper steel with high strength and toughness. Further increases in strength can be achieved by cold forming and subsequent precipitation hardening.
These products are typically used for parts requiring corrosion resistance and high strength up to 316°C. However, their use is not limited to such applications. However, use is not limited to such applications.
Certain processing methods and operating conditions can cause these products to become susceptible to stress corrosion cracking.
For applications such as bolting where stress corrosion cracking is possible, the product should be aged for a minimum of 4 hours at the highest temperature compatible with the strength requirements, but in no case lower than 552°C.
