N690
The cobalt-alloyed N690 by Böhler (not to be confused with the lower-grade N695!) is a very reliable upper middle-grade steel we use at our Solingen manufacture for a wide variety of projects. The fine-grained N690, which ranks above 440C, offers convincing performance data in all areas. It is often sold as N690Co – the "Co" stands for cobalt and describes the exact same steel.
