Hello Dave. The idea is to achieve a maximum hardness 25 HRc after cold forging with heat treatment. Before the forging I would like the less hardness possible of course.
These values are arbitrary and are subject to change, but to start the idea is that. 2018-07-10 13:15 GMT-03:00 Dave Cole <[email protected]>: > So these need to be hardened after cold forging ? > > You want them to have a max 25 HRc after forging and prior to heat > treatment? > > Dave > > > > On 7/10/2018 11:54 AM, Leonardo Marsaglia wrote: > >> Hello to all. >> >> I'm trying to figure out wich is the best material for making cold formed >> bolts wich need to have 25 HRc of maximum hardness. >> >> I was thinking about using 1022 steel wich is suitable for cold forging >> but >> I'm afraid the hardness process will be much more complicated than just >> quenching and tempering. >> >> Then I was thinking about 1045 steel but I'm not sure how good it would be >> for the cold forging process. >> >> Do you have any hints or advices about this? >> >> Thank you as always! >> >> Leonardo. >> ------------------------------------------------------------ >> ------------------ >> Check out the vibrant tech community on one of the world's most >> engaging tech sites, Slashdot.org! http://sdm.link/slashdot >> _______________________________________________ >> Emc-users mailing list >> [email protected] >> https://lists.sourceforge.net/lists/listinfo/emc-users >> > > ------------------------------------------------------------ > ------------------ > Check out the vibrant tech community on one of the world's most > engaging tech sites, Slashdot.org! http://sdm.link/slashdot > _______________________________________________ > Emc-users mailing list > [email protected] > https://lists.sourceforge.net/lists/listinfo/emc-users > ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
