Advantages
- No heat treatment required in the precipitation hardened condition of supply
- high hardness of up to 44 HRC after precipitation hardened
- isotropic mechanical properties
- good machinability in the precipitation hardened condition of supply
- excellent electrical discharge machinability
- excellent polishability
- excellent weldability
- suited for gas and bath nitriding treatments serving to improve surface wear resistance; no hardness decrease during bath nitriding thanks to high retention of hardness at temperatures up to 570°C (low over ageing tendency); in the solution annealed condition, nitriding and precipitation hardening can be carried out in one step
- suited for chromium plating and for any other type of surface coating
- simple heat treatment in the solution annealed condition of supply (for order please inquire)
- minimum dimensional changes during precipitation hardening
