Method for in-die shaping and quenching of martensitic tubular body |
摘要 |
A process that combines tubular body pressure induced shaping at elevated temperatures with a controlled rapid quenching operation using a gaseous quenching medium in a common unit. The achievable cooling rate permits the in-die shaping and quenching of tubular structural components of martensitic steels without requiring the use of a separate discrete quenching.
