BÖHLER N700 GBW

BÖHLER N700 is a corrosion resistant steel in the form of bars, wire, forgings in the solution annealed condition. It is a martensitic, precipitation hardenable chromium-nickel-copper steel with high strength and toughness. Further increases in strength can be achieved by cold working followed by precipitation hardening.

These products are typically used for parts that require corrosion resistance and high strength. Improved corrosion resistance compared to the 13% or 17% chromium steels. Various remelting processes are used to improve steel purity and homogeneity. (ESU, DESU, VLBO). Certain processing methods and operating conditions can make these products susceptible to stress corrosion cracking. For applications such as threaded fasteners where stress corrosion is possible, the product should be age-hardened at a minimum of 4 hours at the highest temperature consistent with the strength requirements, but in no case lower than 552°C.

Typical applications for engineering are instruments in the field of surgery and dentistry but also e.g. components for aerospace, reactor construction, highly stressed pump parts, springs, ship shafts, and many more.
