J1: Danfaraba jumɛn bɛ nɛgɛ 4140 ni 4340 cɛ?
A1: Nickel. 4340 contains ~1.8% nickel, while 4140 contains none. This nickel gives 4340 much higher toughness and allows it to harden deeper in thick sections. If your part is thick (>100 mm) ani a mago bɛ core fanga caman na, aw bɛ 4340 sugandi.
J2: Yala 34CrNiMo6 ni 4340 ye kelen ye wa?
A2: U bɔlen don ɲɔgɔn fɛ kosɛbɛ nka u tɛ kelen ye. 34CrNiMo6 (1.6582) ye Erɔpu (DIN) sariya ye, min ka teli ka kɛ ni karɔbɔni ka dɔgɔn dɔɔnin nka a ka chrome ka ca ni AISI 4340. Nka, baara gɛlɛn fanba la, u bɛ jate baarakɛcogo ɲɔgɔndanw ye minnu bɛ se ka ɲɔgɔn falen.
