O fa'ailoga fa'apisinisi o lo'o gaosia i foliga eseese ma tulaga fa'apitoa. O fa'ameamea u'amea o lo'o i ai se tulaga maualuga tele e fa'agata ai fa'amamafa maualuga tele i lalo o le fa'aalumaga o togafitiga vevela, e o'o atu ai i le filifiliga o lenei fa'ameamea pe a gaosia fa'amau u'amea fa'aaogaina i fausaga tau alamanuia. maualuga carbon anotusi ma mea e sili atu le maualuga nai lo le uʻamea mama, lea e matua vaivai.O le mea moni, i le faaopoopo atu i le carbon, faʻamautu mea faʻapipiʻi e pei o le manganese, silicon, sulfur, phosphorus, ma o nisi taimi e oʻo lava i le vanadium (ua faʻaopoopoina le vanadium i le uʻamea uʻamea e manaʻomia ai le elasticity) o lo'o maua i totonu o u'amea.
I totonu o fale faufale, faʻapipiʻi faʻapipiʻi ma nati e faʻaaogaina lautele i le gaosiga o fale, alalaupapa, dams ma power plant. faʻaaogaina electrodes, faʻalagolago i le manaʻoga e faʻapipiʻi le ipu uʻamea ma le beam.O auala faʻafesoʻotaʻi taʻitasi e iai ona lava lelei ma mea le lelei, lea o le a tatou iloiloina i lalo.
Sikuli fausaga faʻaaogaina i le fausiaina o fesoʻotaʻiga o loʻo faia i le sila maualuga, e masani lava vasega 10.9.Grade 10.9 o lona uiga o le malosi o le malosi o le faʻailoga faʻapipiʻi e tusa ma le 1040 N / mm2, ma e mafai ona tumau i le 90% o le mamafa atoa. faʻaaogaina i le tino sikuli i totonu o le itulagi elastic e aunoa ma le deformation tumau.Faatusatusa i le 4.8 uʻamea, 5.6 uʻamea, 8.8 mago uʻamea, sikulima fausaga e maualuga atu le malosi tensile ma e sili atu ona faigata togafitiga vevela i le gaosiga.
E ese mai le tulaga masani o le hexagon bolts ma nati, o le hexagon bolts ma nati masani e gaosia e tusa ai ma le DIN931 faʻataʻitaʻiga e pei o le afa afa, e tusa ai ma le DIN933 faʻataʻitaʻiga e pei o ni mea faʻapipiʻi atoa, ma faʻamau hexagonal e faigofie, e masani ona gaosia e tusa ai ma le DIN6914 standard.Coupling nuts on sikulima fausaga e sili atu foi aano ma le maualuga nai lo nati hex masani gaosia i le DIN934, faʻaalia le maualuga o le faʻalavelave faʻalavelave, gaosia i le DIN6915. O faʻailoga o lenei fausaga o loʻo faʻailogaina 10HV ma e masani lava matt black phosphating mo le faʻaleleia atili o le siosiomaga ele tetee poʻo le vevela vevela galvanized poʻo le loloto. chrome matt siliva, e lua uma ma se uʻamea faʻauma. Latou te faʻaaogaina i le zinc ma e lelei le teteʻeina o le siosiomaga.
