Ingxubevange C-4 Ukwenziwa kwemichiza:

Ingxubevange yeC-4 yingxubevange yenickel-chromium-molybdenum ebalaseleyo.
Uzinzo oluphezulu lobushushu njengoko kungqinwa yi-ductility ephezulu kunye nokumelana nomhlwa nokuba
emva kokuguga kwi-1200 ukuya kwi-1900 F (649 ukuya kwi-1038 C) uluhlu. Le ngxubevange imelana nokwakheka
ye-grain-boundary precipitates kwindawo echatshazelwe bubushushu be-weld, ngaloo ndlela iyenza ifaneleke
kwizicelo ezininzi zenkqubo yeekhemikhali kwimeko ene-welded. C-4 ingxubevange kwakhona
inokumelana okugqwesileyo kuxinzelelo lwe-corrosion cracking kunye ne-oxidizing atmospheres ukuya kuthi ga
1900 F (1038 C).

I-alloy ye-C-4 i-alloy inokumelana okukhethekileyo kwiintlobo ezininzi zenkqubo yemichiza
iindawo ezingqongileyo. Ezi ziquka i-acids yamaminerali eshushu, i-solvents, i-chlorine
kunye ne-chlorine engcolileyo yemidiya (i-organic and inorganic), i-chlorine eyomileyo, i-formic kunye
iiacetic acids, iacetic anhydride, kunye namanzi olwandle kunye nezisombululo zebrine.
Ingxubevange ye-C-4 ingxubevange inokubunjwa, ishushu, kunye nefuthe eligqithisiweyo. Nangona i
Ingxubevange ithande ukusebenza nzima, inokutsalwa ngokunzulu ngempumelelo, ijikelezwe, icofe yenziwe okanye
kubethelwa ngenqindi. Zonke iindlela eziqhelekileyo ze-welding zingasetyenziselwa ukudibanisa i-alloy C-4
i-alloy, nangona i-oxy-acetylene kunye neenkqubo ze-arc eziphantsi kwamanzi azikhuthazwa
xa into eyenziweyo yenzelwe ukusetyenziswa kwinkonzo yokubola. Izilumkiso ezikhethekileyo
kufuneka kuthathwe ukuphepha igalelo lobushushu obugqithisileyo.
