... of forging press required, at least 450 MN. These facilities are limited to preheat temperatures of approximately 1200 °C (2200 °F) typical of gas-fired furnaces, so the forging process imparts a significant amount of work to the forging billet, raising the strength of the forged part substantially. Smaller...
