This low carbon martensitic steel is hardenable (maraging steel) and presents a very high tensile strength. In the delivered tempers, Durinox can be hardened in order to reach a tensile strength of approximately 2000 N/mm2. This high performance steel allows an easy cold working of parts; Durinox has a very high fatigue strength limit and the cutting edges, often critical in mechanical clock industry, for example, remain smooth. The hardening of parts (typically at 480°C 3h under vacuum or under inert atmosphere) results in a high degree of hardening without perceptible dimensional change.

Typical uses
Springs, pallet forks, wheels, bridges, connectors, various parts subjected to high stresses, etc.
