Description

The matrix structure consists of a highly tough, age-hardenable nickel martensite. The chromium content of 13.5 % provides good corrosion resistance. Finish-machining is performed in the solution-annealed, as- delivered condition. Subsequent age-hardening takes place at a relatively low temperature of 480 °C and can be conducted, for example, in a convection air furnace or an electrically heated chamber furnace.
