hi
why isn't allowed heat treating in the range(590+/- 10) for TM (THERMO MECHANICAL) STEEAL?

These steels are produced with accelerated/controlled cooling to get
the improved mechanical properties, particularly toughness. due to
this inherent charecterstic of TMCP process, these can't be formed at
elevated temperatures.
check the link for more info about the process.

ASME SA 841 is TMCP steel
