Kulesi sihloko se-SEO, i-sakysteel inikeza umbono ophelele we-Insimbi engu-4140, okuhlanganisa ukwakheka kwayo kwamakhemikhali, izakhiwo zemishini, izinqubo zokwelapha ukushisa, kanye nokusetshenziswa okuvamile.
Ukuhlukaniswa kwensimbi engu-4140
I-4140 iyinsimbi ephansi ye-alloy ewela ngaphansi kohlelo lokuhlukaniswa kwe-SAE-AISI. Yaziwa nangokuthiI-AISI 4140, EN19 (eYurophu), futhiI-SCM440 (eJapane)Isiqu esithi “4140” sibhekisela kokuqukethwe kwe-alloy ethile:
-
“41” isho insimbi ye-chromium-molybdenum
-
“40” imele okuqukethwe kwekhabhoni okulinganiselwe (0.40%)
Insimbi engu-4140 ayiyona insimbi engagqwali, njengoba ingenayo i-chromium eyanele ukunikeza ukumelana nokugqwala. Esikhundleni salokho, iyaziswa ngamandla ayo okusebenza kanye nokuqina ngemva kokwelashwa ngokushisa.
Ukwakheka Kwamakhemikhali Kwensimbi engu-4140
Ukwakheka kwamakhemikhali kwe-4140 yikho okwenza kube nezakhiwo zayo ezithuthukisiwe zemishini. Izinhlobo ezijwayelekile zifaka:
-
Ikhabhoni (C):0.38% – 0.43%
-
I-Chromium (Cr):0.80% – 1.10%
-
I-Manganese (Mn):0.75% – 1.00%
-
I-Molybdenum (Mo):0.15% – 0.25%
-
I-Silicon (Si):0.15% – 0.35%
-
I-Phosphorus (P):≤ 0.035%
-
I-Sulfur (S):≤ 0.040%
Lezi zinto zisebenza ndawonye ukuthuthukisa ukuqina, ukumelana nokuguguleka, kanye nokuqina okuphelele, okwenza i-4140 ibe yinto esetshenziswa kakhulu ezingxenyeni zemishini ezidinga amandla.
