Machinability
Forgeability
The grade can be hot forged in the 900/1250°C temperature range. Resolving will be necessary to achieve maximum hardness.
Weldability
The grade can be welded using most processes. Welding should preferably be done before ageing to avoid embrittlement of the heat affected zone.
Corrosion resistance
The grade is very corrosion resistant but must be passivated. The microstructure contains little or no chromium carbides, which makes it less susceptible to intergranular corrosion.
