Applications
Carbon steel EN 10293 GE300 is used for cast gears, rollers, cranks and striking plates, with other documented applications including liners and hammer components. Other cast components used in this material family include housings, supports, brackets, frames and connecting parts. Typical settings include industrial, agricultural, construction and railway equipment, as well as machinery replacement and maintenance.
Pressure-retaining, low-temperature or lifting duties require their own component specification.
