Document Type and Number:
WIPO Patent Application WO/2016/053612
Kind Code:
A3
Abstract:
A method for forming and treating a steel article of a high strength and ductile alloy. The method includes the steps of providing a starting steel composition for the steel article, preheating the composition, heating the starting material to a peak temperature range in less than forty seconds, holding the heated steel composition at the peak temperature range for between two and sixty seconds, quenching the heated steel composition from the peak temperature range to below 177 °C (350 °F) at a temperature rate reduction of 200 to 3000 °C/sec (360 and 5400 °F/sec), removing residual quench media from the surface of the quenched steel composition, tempering the quenched steel composition at a temperature of 100 to 704 °C (212 to 1300 °F); and air cooling the tempered steel composition to less than 100 °C (212 °F) to form a steel having desired mechanical properties.
