Product Description

BÖHLER N701 is a high quality, vacuum remelted, corrosion resistant steel for aerospace applications in the form of bars for machining up to 200 mm in diameter.

It is a martensitic, precipitation hardenable chromium-nickel-copper steel with high strength and toughness.

These products are typically used for parts that require corrosion resistance, high strength up to 600 °F, and exhibit good toughness & strength in the transverse direction of large dimensions. 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.
