Uhereye ku bipimo fatizo byerekana imikorere, imbaraga za nominal zingana zingana na 10.9 zo mu rwego rwo hejuru zifite imbaraga zingana na 1000MPa, mugihe imbaraga zumusaruro zibarwa nka 900MPa binyuze mubipimo byimbaraga (0.9). Ibi bivuze ko iyo bikorewe imbaraga zingutu, imbaraga ntarengwa zishobora gukomera ni hafi ya 90% yimbaraga zavunitse. Ibinyuranye, imbaraga za nominal tensile zingana na 12.9 zo mucyiciro cyongerewe kugera kuri 1200MPa, kandi imbaraga zumusaruro zingana na 1080MPa, byerekana uburakari bukabije kandi butanga umusaruro. Ariko, mubihe byose, urwego rwohejuru rushobora gusimbuza urwego rwo hasi rutarobanuye. Hariho ibitekerezo byinshi birimo inyuma yibi:
1. Gukora neza: Nubwo imbaraga-zohejuru zifite imikorere isumba iyindi, ibiciro byo gukora nabyo byiyongera bikwiranye. Mubihe aho imbaraga zikenewe zidakenewe, ukoresheje urwego rwo hasi rushobora kuba ubukungu kandi bushyize mu gaciro.
2. Kurinda ibice byunganira: Mugihe cyo gushushanya, akenshi habaho itandukaniro nkana ryimbaraga hagati ya bolts nimbuto kugirango ubuzima burambye kandi amafaranga make yo kubungabunga mugihe cyo gusenya no kuyasimbuza. Niba bisimbuwe uko bishakiye, birashobora guhungabanya iyi mpirimbanyi kandi byihutisha kwangiza ibikoresho nkibinyomoro.
3. Ingaruka zidasanzwe zikorwa: Uburyo bwo kuvura hejuru nka galvanizing bushobora kugira ingaruka mbi kumashanyarazi akomeye, nka hydrogen embrittlement, bisaba gusuzuma neza mugihe uhisemo ubundi buryo.
4. Ibisabwa gukomera kubintu: Mubidukikije bimwe na bimwe bifite imitwaro isimburana, gukomera kwa bolts biba ngombwa cyane. Kuri iyi ngingo, gusimbuza buhumyi imbaraga-zohejuru zishobora gutera kuvunika hakiri kare kubera gukomera kwibikoresho bidahagije, ari nako bigabanya kwizerwa kwimiterere rusange.
5. Uburyo bwo gutabaza umutekano: Mubisabwa bimwe bidasanzwe, nkibikoresho bya feri, bolts igomba gucika mubihe bimwe na bimwe kugirango habeho uburyo bwo kurinda. Muri iki gihe, gusimburwa kwose bishobora gutuma kunanirwa imikorere yumutekano.
Muncamake, hari itandukaniro rikomeye mumiterere yubukanishi hagati yingufu zikomeye zo mu cyiciro cya 10.9 nicyiciro 12.9. Ariko, mubikorwa bifatika, guhitamo kwabo bigomba gusuzumwa neza hashingiwe kubikenewe byihariye. Guhuma buhumyi ubukana bwinshi ntibishobora kongera ibiciro bitari ngombwa gusa, ariko kandi bizana umutekano muke. Birakenewe gusobanukirwa byimazeyo ibiranga imikorere nimbogamizi zikoreshwa za bolts zitandukanye, kugirango tumenye neza ko ibyatoranijwe byatoranijwe bishobora kuzuza ibisabwa kugirango habeho umutekano no kwizerwa byimiterere.
