Up to what temperatures are high alloy steels heated before treating them by oxygen cutting?

Up to what temperatures are high alloy steels heated before treating them by oxygen cutting? Correct Answer 675°C

In oxygen cutting process, not all steels can be treated by this method. Only high alloy steels can be treated by this method. These steels need to be preheated before oxygen cutting. The temperature range up to which these steels are preheated is about 650°C to 700°C.
