Flame cutting Manganese steel?

Flame cutting Manganese steel?

Flame cutting Manganese steel?

(OP)
We have received an inquiry asking if we can flame cut Manganese steel plate, up to 2".  We usually don't cut anything more exotic than 4140 plate.  Are there any problems/limitations?  I found a couple supplier sites discussing flame cutting, with seemingly contradictory statements.

(States you can cut with Tensamang with standard torch equipment).

RE: Flame cutting Manganese steel?

Gas cutting should be possible as we gas cut runners and risers/feeders in our high Mn steel castings. However,this is followed by heat treatment of the casting i.e heating to 1025-1050 C soaking,followed by water quenching.

I have seen users of plates upto 12 mm using these after gas cutting,without any heat treatment. However, the carbon in these plates is about 0.6%.
