BÖHLER N700 is a high-quality corrosion-resistant steel in aerospace quality, in the form of bars, wire and forgings with a diameter/thickness of 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 increases in strength can be achieved by cold forming and subsequent precipitation hardening. These products are typically used for parts requiring corrosion resistance and high strength up to 316°C. However, their use is not limited to such applications. 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. For applications such as bolting where stress corrosion cracking is possible, the product should be aged for a minimum of 4 hours at the highest temperature compatible with the strength requirements, but in no case lower than 552°C.

Uddeholm Vanadis 4 Extra SuperClean is the most versatile pm tool steel on the market today, combining high wear resistance with very good ductility and resistance to chipping of edges. Excellent machinability in both soft and hard condition ensures advantages in both tool making and tool maintenance. Uddeholm Vanadis 4 Extra SuperClean is also available as powder for processing by electron beam melting technology (EBM). This powder has the same chemical composition as the PM material. Benefits Reliable production with low risk of edge chipping Best combination of high hardness, wear resistance and chipping resistance High compressive strength Best stock standard program of all PM grades Standard specification AISI D2 / AFNOR de type Z136 CDV 5.4
