Iyini i-AISI 5140 steel?
I-ASTM grade 5140 iyizinga elilodwa lensimbi ye-structural alloy ku-ASTM A29 okujwayelekile ukuze kusetshenziswe okuvamile. Ipuleti yensimbi engu-5140 isetshenziswa kabanzi ezingxenyeni eziphansi nezicindezelwe ngokusesilinganisweni zezimoto, izinjini nemishini lapho kudingeka khona indawo eqinile, eqinile yokumelana nokugqoka. I-Gnee ingumphakeli ochwepheshile wepuleti le-5140 & ibha eyindilinga futhi sigcina ububanzi bosayizi wepuleti elingu-5140 esitokweni ukuze lithunyelwe ngokushesha. Xhumana nathi nganoma yisiphi isicelo se-AISI 5140 sempahla yepuleti kanye nenani lensimbi elingcono kakhulu le-5140 grade.
Inzuzo Yokuncintisana ye-AISI 5140 ipuleti lensimbi lensimbi e-Otai:
- Itholakala esitokweni ukuze ithunyelwe ngokushesha
- Amandla aphezulu,
- Ukuqina okuphezulu
- Ukuqina okuhle
- Ukumelana okuphezulu nezakhiwo ezishisayo.
- Intengo yokuncintisana
1. Ububanzi Bokunikezela be-AISI/ASTM 5140
Ibha Eyindilinga: ububanzi 20mm - 300mm
Steel Plate kanye Steel Block: ukujiya 10-200mm x ububanzi 300-2000mm
- 10-80mm ukujiya 5140 plate ayatholakala ngaso sonke isikhathi esitokisini,
- Ipuleti lokujiya elingu-90-200mm lizoba ukukhiqizwa okusha ezinsukwini eziyi-15-30 zokuhola.
I-Surface Finish: Indawo Emnyama, Indawo Eyimilled noma Indawo Epholile ngokwezidingo ezinikeziwe.

5. Ukwenziwa kwe-5140 Alloy Steel
Izinga lokushisa elishisayo lokubumba: 1050-850 ℃.
6. ASTM 5140 Steel Heat Treat
Shisisa ufike ku-680-720 ℃, uphole kancane. Lokhu kuzokhiqiza ubulukhuni obungu-5140 obungu-241HB (ukuqina kweBrinell).
- Noramlizing of steel grade 5140
Izinga lokushisa: 840-880 ℃.
- Ukwenziwa lukhuni kwensimbi engu-5140
Yenza lukhuni kusuka ekushiseni okungu-820-850, 830-860℃ okulandelwa amanzi noma ukucisha uwoyela.
- Ukushisa kwempahla ye-SAE 5140
Izinga lokushisa: 540-680 ℃.
7. Izicelo ze-AISI Grade 5140
Insimbi ye-AISI 5140 ingasetshenziselwa izingxenye eziphansi nezicindezelwe ngokumaphakathi zezimoto, izinjini nemishini lapho kudingeka khona indawo eqinile, evikelayo. Ukuqina njengobuso kuqina cishe ngama-54 HRC. Izinsimbi ze-SAE 5140 zingaphinde zibe ezemboni yobunjiniyela basolwandle, izimboni zokucubungula amakhemikhali, imikhumbi ebhayela nokucindezela, izitshalo zamandla enuzi njll.
Uma unemibuzo mayelana nokucaciswa kwe-5140, nanoma yimiphi imibuzo mayelana ne-5140 vs 4130, 5140 vs 4340 njll, sicela usithinte ukuze uthole ukwesekwa kobuchwepheshe noma nini.
