303 icyuma kitagira umuyonga 303 icyuma kibisi
Ibisobanuro bigufi:
Surface irangiza 303 nicyuma gikata kubusa ibyuma birimo sulfure na seleniyumu, kubisabwa aho gukenera kubuntu bisabwa mbere na mbere kurangiza ni hejuru.303 ibyuma bidafite ingese bitezimbere gukata no guhangana nubushyuhe bwo hejuru.Byinshi bikwiranye nubwiherero bwikora, bolts na nuts.
303 ibyuma bitagira umuyonga ni austenitike yubusa-gukata ibyuma bitagira umwanda, kugirango ubashe kunoza imikorere yicyuma, urashobora kongerwaho bitarenze 0.60 Mo mubyuma, birashobora kurwanya gukuraho, ibicuruzwa byiza gukata no kurwanya umuriro.Kurwanya ruswa.Imiterere yubukanishi bwa 303 ibyuma bitagira umuyonga bifatanye kandi bitesha umutwe, imbaraga zingana ni 515 MPA, umusaruro ni 205 MPA, naho kurambura ni 40%.Ubukomere busanzwe HRB 90-100, HRC 20-25 kubyuma bitagira umwanda 303 Icyitonderwa: HRB100 = HRC20
