Thanks for the reply
I know that this steel is not designed for heat treatment, but when it is heat treated, it hardens to a certain value. As far as I looked in all internet researches, it does not show the copper content. This is what I really want to ask how much it would be if it were.
For example, what is the effect of %0.268. Copper ?
With so little C this material will not respond to HT.
While some martensite will form it will be very lean in composition and therefore not very hard at all.
Cu will behave similar to Ni and reduce hardenability.
