5. Conclusions
- The reduction of reheating temperature to 1200 °C led the steel ISO 5832-9 to have better mechanical and corrosion properties than when soaked at 1250 °C.
- Processing loads were not significantly increased with the reduction of the reheating temperature. This fact indicates that existing processing equipment can continue to be used.
- The decrease of interpass times and reduction of reheating temperature shorten the processing time, causing production costs to be reduced, which would help to reduce the price of prosthesis’ implantation greatly.
