    Description

    25Х17Н2 steel is used: for the manufacture methods of hot and cold deformation and machining of various parts with high ductility for aircraft and instrumentation, exposed to shock loads and working temperatures up to +500−530 °C; products exposed to slightly aggressive media at room temperature.

    Note

    Steel corrosion-resistant martensitic class.
