I-4340 Steel Bar UT Test :
Imigoqo yethu eyi-4340 alloy steel flat ihlolwa ngokuqinile nge-ultrasonic (UT) ukuze kuqinisekiswe ukuzwakala kwangaphakathi kanye nesakhiwo esingenasici. Le ndlela yokuhlola engonakalisi ithola ukungaqhubeki kwangaphakathi okufana nokuqhekeka, i-voids, nokufakiwe okungabonakali ngeso lenyama. Ukuhlolwa kwe-UT kwenziwa ngokuhambisana namazinga emboni, kuqinisekiswe ukuthi ibha ngayinye ihlangabezana nezidingo zokusebenza okuphezulu kwe-aerospace, yezimoto, kanye nezinhlelo zokusebenza zobunjiniyela ezisindayo. Ukulawulwa kwekhwalithi okuthembekile kuqinisekisa ukumelana nokukhathala okuthuthukisiwe, ubuqotho besakhiwo, kanye nokuzethemba kwekhasimende.
I-4340 Alloy Bar PMI Test :
Ukuqinisekisa ukulandeleka kwezinto ezibonakalayo nokuhambisana nokucaciswa kwamakhasimende, ukuhlolwa kwe-PMI (Positive Material Identification) kwenziwa kuma-AISI 4340 Alloy Steel Flat Bars kusetshenziswa ama-spectrometer athuthukile noma ama-X-ray fluorescence (XRF) analyzer. Le ndlela yokuhlola engabhubhisi iqinisekisa ukwakheka kwamakhemikhali kwenombolo ngayinye yokushisa, iqinisekisa ukuthi ifinyelela ububanzi obudingekayo be-alloying efana ne-Ni, Cr, ne-Mo.
Ukuhlolwa Kokuqina Kwebha ye-4340 :
Ukuqinisekisa isimo sokwelashwa kokushisa nokuqinisekisa ukusebenza kwemishini, ukuhlolwa kokuqina kwenziwa kuma-AISI 4340 Alloy Steel Flat Bars kusetshenziswa izindlela ze-Rockwell noma ze-Brinell. Kumabha acishiwe napholile, ububanzi obujwayelekile bokuqina bungu-24 kuya ku-38 HRC. Amanani okuqina arekhodwa ezindaweni eziningi endaweni yonke kanye nasezingxenyeni ezihlukene ukuze kuqinisekiswe ukufana. Imiphumela isiza ukuqinisekisa ukufaneleka kwensimbi ekusetshenzisweni okufunayo okubandakanya ukucindezeleka okukhulu nomthelela.
