Jul 16, 2019 · To the OP:4140HT (Heat treated) and 4140 QT (Quenched and tempered) and 4140 HTSR (Heat treated & stress relieved) and 4140 Pre-Hard are all basically the same thing. They are generally in the range 0f 26-32 HRc. Movement during/after machining may or may not be problematic, depending on the amount and configuration of material to be removed
