BÖHLER N701

BÖHLER N701 is a corrosion-resistant steel available in the form of bars, wire, and forgings in the solution-annealed condition.

It is a martensitic, precipitation-hardenable chromium-nickel-copper steel with high strength and toughness. Further strength enhancements can be achieved through cold working and subsequent precipitation hardening.

These products are typically used for parts that require higher corrosion resistance than conventional 13% or 17% chromium steels and high strength up to 316°C. However, their use is not limited to such applications. The vacuum melting process is used to improve steel purity and homogeneity.

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

Typical applications include reactor construction, highly stressed pump parts, springs, ship shafts, plastic injection molds and compression molds, and medical instruments.
