Ukuhlolwa kwe-UT yensimbi engu-4340:
Imigoqo yethu eyisicaba yensimbi engu-4340 ihlolwa nge-ultrasonic eqinile (UT) ukuqinisekisa ukuthi iphilile ngaphakathi kanye nesakhiwo esingenamaphutha. Le ndlela yokuhlola engonakalisi ithola ukungaqhubeki kwangaphakathi njengokuqhekeka, izikhala, kanye nokufakwa okungabonakali ngeso lenyama. Ukuhlolwa kwe-UT kwenziwa ngokuhambisana nezindinganiso zemboni, ukuqinisekisa ukuthi ibha ngayinye ihlangabezana nezidingo zokusebenza okuphezulu zezinhlelo zokusebenza zezindiza, izimoto, kanye nobunjiniyela obukhulu. Ukulawulwa kwekhwalithi okuthembekile kuqinisekisa ukumelana nokukhathala okuthuthukisiwe, ubuqotho besakhiwo, kanye nokuzethemba kwamakhasimende.
Ukuhlolwa kwe-PMI ye-4340 Alloy Bar:
Ukuqinisekisa ukulandeleka kwezinto kanye nokuhambisana nemininingwane yamakhasimende, ukuhlolwa kwe-PMI (Positive Material Identification) kwenziwa kuma-AISI 4340 Alloy Steel Flat Bars kusetshenziswa ama-spectrometer athuthukisiwe noma ama-X-ray fluorescence (XRF) analyzers. Le ndlela yokuhlola engonakalisi iqinisekisa ukwakheka kwamakhemikhali kwenombolo ngayinye yokushisa, iqinisekisa ukuthi ihlangabezana nobubanzi bezinto ezidingekayo njenge-Ni, Cr, kanye ne-Mo.
Ukuhlolwa Kokuqina Kwebha 4340:
Ukuqinisekisa isimo sokwelashwa kokushisa nokuqinisekisa ukusebenza komshini, ukuhlolwa kobulukhuni kwenziwa kuma-AISI 4340 Alloy Steel Flat Bars kusetshenziswa izindlela zeRockwell noma zeBrinell. Kuma-clocked and tempered bars, ububanzi obujwayelekile bobulukhuni bungu-24 kuya ku-38 HRC. Amanani obulukhuni aqoshwa ezindaweni eziningi ebusweni nasezingxenyeni ezihlukene ukuqinisekisa ukufana. Imiphumela isiza ukuqinisekisa ukufaneleka kwensimbi ekusetshenzisweni okudinga ukucindezeleka okukhulu kanye nomthelela.
Umbiko Wokuhlola Ibha Yensimbi Eyisicaba engu-4340:
Ngokusho kwe-: Standard ASTM A370-24a.
