Under the condition of adequate intensity for 20MnMo steel forgings,using the method of sub-temperature quenching+high-temperature tempering heat treatment process can obviously improve the low-temperature impact toughness for forgings.

There are vast amounts of research published on weldability of low—alloy steels but until now there is little reported work on that of 20MnMo steel.
