I-AISI 4140 SCM440 DIN 42CrMo4 1.7225 Forged Alloy Steel Round Bar
Imininingwane Yomkhiqizo
I-AISI 4140 ichazwa njengensimbi ephansi ye-alloy ene-1% Cr-Mo njengezinto eziqinisa ingxubevange. Uma iqhathaniswa ne-AISI 4130, inokuqukethwe kwekhabhoni ephezulu okunokulinganisela okuhle kwamandla, ukuqina, ukuhuzuka kanye nokumelana nomthelela namandla okwelapha ukushisa, kodwa impofu ezicini zekhono lokushisela.I-AISI 4140 ngokuvamile ihlinzekwa esimweni esicishiwe nesithambile esinobunzima obungu-28-32HRC.
I-4140 inamandla aphezulu, ikhono eliqinile, ukuqina, kanye nokuguqulwa ngesikhathi sokucisha.Inamandla aphezulu okukhasa kanye namandla okubekezela emazingeni okushisa aphezulu.Isetshenziselwa ukukhiqiza ama-forging adinga amandla aphezulu kanye nezingxenye ezinkulu ezicishiwe neziqinile kunensimbi engu-4135, njengamagiya amakhulu okudonsa kwesitimela, amagiya okudlulisa amandla, ama-asi angemuva, izinduku zokuxhuma neziqeshana zasentwasahlobo ezilayishwe kakhulu.
