Glenn Posted May 12, 2013 Share Posted May 12, 2013 Why not ask the place where you got the steel or the supplier of that type steel? If they are using or selling the stuff they should also have the HT information. Link to comment Share on other sites More sharing options...
forgemaster Posted May 13, 2013 Share Posted May 13, 2013 The supplier should be able to supply you a chart/graff showing tempering lines incorporating izod, uts, hardness etc. Link to comment Share on other sites More sharing options...
DClaville Posted May 15, 2013 Share Posted May 15, 2013 it is a non hardenable steel so it can't really be HT'ed much Link to comment Share on other sites More sharing options...
