Imibhobho yentsimbi engenamthungo yoxinzelelo oluphantsi noluphakathiiibhoyilazisetyenziswa ikakhulu kwimibhobho ethutha ulwelo oluphantsi noluphakathi loxinzelelo kwiibhoyila zemizi-mveliso kunye neebhoyila zasekhaya. Izinto ezimele ziyi-10 kunye ne-20 yentsimbi.

Imibhobho yentsimbi engenamthungo yeiibhoyili zoxinzelelo oluphezuluzisetyenziselwa ubukhulu becala ubushushu obuphezulu kunye noxinzelelo oluphezulu lwentloko yothutho lolwelo kunye nemibhobho kwiziko lombane kunye nezibiyile zeplanti yamandla enyukliya. Izinto ezimele i-20G, i-12Cr1MoVG, i-15CrMoG, njl.

Imibhobho yentsimbi engenamthungo yeisichumisi soxinzelelo oluphezuluizixhobo zisetyenziswa ikakhulu ukuthutha ubushushu obuphezulu kunye noxinzelelo oluphezulu lwemibhobho yolwelo kwizixhobo zesichumiso. Izinto ezimele ziyi-20, 16Mn,12CrMo, 12Cr2Mo, njl.

Imibhobho yentsimbi engenamthungo yokuqhekeka kwepetroleum isetyenziswa ikakhulu kwiibhoyila, ukutshintshiselana ngobushushu kunye nemibhobho yokuthutha ulwelo kwizityalo zokunyibilikisa i-petroleum. Izinto zayo ezimele ziyi-15mog, i-15CrMoG, i-12crmog, njl.

Imibhobho yentsimbi engenamthungo yeesilinda zegesi isetyenziswa ikakhulu ukwenza iisilinda ezahlukeneyo zerhasi kunye nehydraulic. Izinto zayo ezimele ziyi-37Mn, 34Mn2V, 35CrMo, njl.

Imibhobho yentsimbi engenamthungo eshushu eqengqelekayo isetyenziselwa iipropu zehydraulic, ezisetyenziswa ikakhulu ukwenza izixhaso zehydraulic, iisilinda kunye neentsika kwimigodi yamalahle, kunye nezinye iisilinda zehydraulic kunye neentsika. Izinto zayo ezimele ziyi-20, 45, 27SiMn, njl.

Imibhobho yentsimbi engenamthungo epholileyo okanye ebandayo eqengqelekayo isetyenziswa ikakhulu kwizakhiwo zoomatshini kunye nezixhobo zokucinezela ikhabhoni, ezifuna ukuchaneka komgangatho ophezulu kunye nokugqiba kakuhle komphezulu. Izinto zayo ezimeleyo ziquka i-20, i-45 yensimbi, njl.

Imibhobho yentsimbi engenamthungo etsalwa ngokubanda kunye nemibhobho yentsimbi enokwakheka okukhethekileyo isetyenziswa ikakhulu ukwenza iindawo ezahlukeneyo zesakhiwo kunye neenxalenye. Zenziwe ngentsimbi ye-carbon structural high quality kunye ne-low-alloy structural steel.

Imibhobho yentsimbi engenamthungo engaphakathi kwidayamitha echanekileyo ye-hydraulic kunye ne-pneumatic cylinders isetyenziswa ikakhulu ukwenza imibhobho yentsimbi etsalwa ngokubanda okanye eqengqelekayo nengenamthungo eneidayamitha ezichanekileyo zangaphakathi kwi-hydraulic kunye ne-pneumatic cylinders.
