BÖHLER N695 is a corrosion-resistant steel with 17%Cr and Mo-addition in the form of bars, wire, forgings, and forging stock. These products have been used typically for parts in general engineering and cutting and non cutting, medical applications , e.g. chisels, knives, osteotomes, scalpels drills, retractors, spreaders, tongs, balls, rollers, needles and rings for corrosion resistant bearings requiring hardness from 58 up to 60 HRC and resistance to wear, corrosion, and oxidation depending on parts design and application but usage is not limited to such applications.

BÖHLER N700 is a martensitic, corrosion-resistant, 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 that require higher corrosion resistance than the usual 13% or 17% chromium steels and high strength. Various remelting processes are used to improve steel purity and homogeneity. (ESR, PESR, VAR). Certain processing methods and operating conditions can make these products susceptible to stress corrosion cracking. For applications such as bolting where stress corrosion cracking 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. Typical engineering applications include surgical and dental instruments as well as aerospace components, reactor construction, highly stressed pump parts, springs and ship shafts.
