(1) Intangiriro y'ibikoresho by'imiyoboro idafite ibyuma:
GB / T8162-2008 (umuyoboro w'icyuma udafite icyerekezo cyo gukoresha imiterere). Ahanini ikoreshwa muburyo rusange nuburyo bwubukanishi. Ibikoresho bihagarariye (amanota): ibyuma bya karubone No 20, No 45 ibyuma; ibyuma bivangwa na Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, nibindi.
GB / T8163-1999 (umuyoboro wicyuma utagira amazi wo gutwara amazi). Ahanini ikoreshwa mugutanga imiyoboro y'amazi mubukorikori nibikoresho binini. Ibikoresho byerekana (amanota) ni 20, Q345, nibindi
GB3087-2008 (umuyoboro w'icyuma udafite icyerekezo cyo gutekesha ingufu ziciriritse). Ahanini ikoreshwa mumiyoboro yo kugeza amazi mabi kandi aringaniye mumashanyarazi no mumashanyarazi. Ibikoresho bihagarariye ni No 10 na No 20 ibyuma.
GB / T17396-2009 (umuyoboro ushyushye utagira ibyuma bya hydraulic). Ikoreshwa cyane cyane mugukora hydraulic, silinderi ninkingi mumabuye yamakara, kimwe nandi mashanyarazi ya hydraulic hamwe ninkingi. Ibikoresho byayihagarariye ni 20, 45, 27SiMn, nibindi
. . Amashanyarazi: imiyoboro ya gazi, imiyoboro y'amazi itanga amazi. 4. Imiyoboro irwanya static yinganda zumuyaga, nibindi.
