4340 Uvavanyo lwe-Steel Bar UT :
Imivalo yethu yentsimbi eyi-4340 yealloy iphantsi kovavanyo olungqongqo lwe-ultrasonic (UT) ukuqinisekisa ukuvakala kwesandi sangaphakathi kunye nolwakhiwo olungenasiphako. Le ndlela yokuvavanya engonakalisiyo ibona ukungaqhubeki kwangaphakathi njengokuqhekeka, i-voids, kunye ne-inclusions engabonakaliyo ngeso lenyama. Ukuhlolwa kwe-UT kuqhutywa ngokuhambelana nemigangatho yoshishino, ukuqinisekisa ukuba ibha nganye ihlangabezana neemfuno eziphezulu zokusebenza kwi-aerospace, i-automotive, kunye nezicelo zobunjineli ezinzima. Ulawulo lomgangatho oluthembekileyo luqinisekisa ukuxhathisa ukudinwa, ukuthembeka kwesakhiwo, kunye nokuzithemba kwabathengi.
Uvavanyo lwe-PMI ye-Alloy 4340 :
Ukuqinisekisa ukulandelwa kwezinto eziphathekayo kunye nokuthotyelwa kwenkcazo yabathengi, uvavanyo lwe-PMI (i-Positive Material Identification) luqhutywa kwi-AISI 4340 Alloy Steel Flat Bars usebenzisa i-spectrometers ephezulu okanye i-X-ray fluorescence (XRF) analyzers. Le ndlela yokuvavanya engonakalisiyo iqinisekisa ukubunjwa kweekhemikhali zenombolo yobushushu nganye, iqinisekisa ukuba idibana noluhlu olufunekayo lwe-alloying efana ne-Ni, Cr, kunye ne-Mo.
4340 Uvavanyo loBulukhuni beBar :
Ukuqinisekisa imeko yonyango lokushisa kunye nokuqinisekisa ukusebenza komatshini, uvavanyo lobunzima luqhutyelwa kwi-AISI 4340 Alloy Steel Flat Bars usebenzisa iindlela ze-Rockwell okanye zeBrinell. Kwimivalo ecinyiweyo kunye nenomsindo, uluhlu oluqhelekileyo lobunzima luyi-24 ukuya kwi-38 HRC. Amaxabiso obunzima arekhodwa kwiindawo ezininzi kuwo wonke umhlaba kunye necandelo elinqamlezayo ukuqinisekisa ukufana. Iziphumo zinceda ukuqinisekisa ukufaneleka kwentsimbi kwizicelo ezifunwayo ezibandakanya uxinzelelo oluphezulu kunye nefuthe.
