I-SAE4340 40CrNiMoA Ingxubevange yepayipi lensimbi engenamthungo

I-SAE4340 40CrNiMoA Alloy Ipayipi Lensimbi Elingenamthungo Isithombe Esifakiwe

Incazelo emfushane:

I-40CrNiMoA ingxubevange yepayipi yensimbi engenamthungo iwukuqina okuphezulu, ipayipi lensimbi yesakhiwo esiqinile.Ukwakheka kwayo ikakhulukazi kuhlanganisa i-chromium, i-nickel, i-molybdenum kanye nenani elincane lekhabhoni, i-silicon, i-manganese nezinye izakhi, ngokusebenzisa izilinganiso ezithile kanye nezinqubo zokwelashwa kokushisa, inokumelana nokugqwala okuhle nokusebenza okuphezulu kwezinga lokushisa.Ngenxa yezakhiwo zayo ezinhle kakhulu zemishini kanye nohlu olubanzi lwezinkambu zohlelo lokusebenza, isetshenziswe kabanzi ezimbonini eziningi.

Inkambu yohlelo lokusebenza

1. Embonini ye-petrochemical, ingasetshenziswa ukwenza imishini ebalulekile njengemikhumbi ephezulu yokucindezela, ama-reactors, ama-heater exchangers, njll, engakwazi ukumelana nemiphumela yokushisa okuphezulu, ukucindezela okuphezulu kanye nemidiya edlayo.

2. Embonini yamandla kagesi, ingasetshenziswa ukwenza izingxenye zamasethi e-generator, ama-boilers, ama-steam turbines nezinye izinto zokusebenza, ezingakwazi ukumelana nomthwalo ophezulu kanye nezimo zokusebenza eziphezulu zokushisa.

3. Emkhakheni we-aerospace, ingasetshenziswa ukwenza izingxenye ezibalulekile ezifana nemishini yokuhlala yendiza kanye nezakhiwo ze-fuselage ukuze kuthuthukiswe ukuphepha nokusebenza kwendiza.

Ngaphezu kwalokho, amapayipi ensimbi e-40CrNiMoA angasetshenziswa futhi ukwenza izingxenye ezibalulekile ezimotweni, emikhunjini, ezitimeleni nakwezinye izimboni ukuthuthukisa ikhwalithi yomkhiqizo nokuthembeka.

Ukucaciswa Kokwelashwa Kokushisa

Ukushisa kokucisha: 850 ºC;ukupholisa: amafutha;izinga lokushisa lokushisa: 600 ºC;okupholisayo: amanzi, amafutha.

Isimo Sokulethwa

Ukulethwa ekwelapheni ukushisa (okujwayelekile, ukuthuthwa kwe-anneal noma ukushisa okuphezulu) noma kungekho isimo sokwelashwa kokushisa, isimo sokulethwa sizoboniswa kwinkontileka.
