Yego, ifite ubushobozi bwo kurwanya ingese kandi ishobora gukoreshwa hanze. Gusiga irangi cyangwa gusiga irangi bishobora kongera igihe cyayo cyo kuramba.
6. Ni ubuhe bunini n'ingano bihari?
Amasahani ya ASTM A572 aboneka mu bunini, ubugari, n'uburebure butandukanye, bitewe n'umutanga. Ubunini busanzwe buri hagati ya mm 3 na mm 200 cyangwa zirenga.
7. Ni gute wahitamo urwego rukwiye rw'icyuma cya ASTM A572?
Koresha Icyiciro cya 42 mu miterere rusange y'imiterere
Icyiciro cya 50 ni cyo gikoreshwa cyane ku biraro n'inyubako
Icyiciro cya 55, 60, 65 kibereye imishinga iremereye cyangwa ikomeye cyane
