BÖHLER N700SA

BÖHLER N700 SA 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 starting material of any size for forging purposes.
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, but their use is not limited to such applications.

Certain processing methods and operating conditions can make these products susceptible to stress corrosion cracking.

For applications such as bolted joints where stress corrosion is possible, the product should be aged for at least 4 hours at the highest temperature compatible with the strength requirements, but in no case lower than 552 °C.
