A hot press forming process consists of forming at the elevated temperature and rapid quenching, which induces phase transformation and results in the press hardening of steel parts. In this study, the hot press forming process of boron steel tube was analyzed by applying different heat transfer coefficients which had been experimentally measured and numerically backward traced.
