Ukuthwala isinyithi kunokuqina okuphezulu, amandla oqinileyo, amandla okudibana kunye nokudinwa, kunye nokuqina okukhulu, okuhlangabezana neemfuno zokumelana nokubola kunye nokumelana nobushushu obuphezulu phantsi kweemeko ezithile.
Isinyithi esine-carbon chromium enesinyithi esinomxholo ophezulu wekhabhoni (0.95-1.05%), ubunzima obufanayo nobufanayo bunokufunyanwa emva kokucima, kunye nobomi obude bokudinwa. Ukungancedi kukuba kuncinci ukunganyangeki kwimithwalo emikhulu kunye nefuthe lokuqina.
I-khabhoni ephezulu yentsimbi ephethe i-chromium isetyenziswa ikakhulu njengamakhonkco kunye nezinto zokuqengqeleka kweebheringi ezijikelezayo phantsi kweemeko ngokubanzi zokusetyenziswa.
Ukuthwala iibhola zentsimbi, njengenxalenye ebalulekileyo yokuthwala, kudlala indima ebaluleke kakhulu.
Ke ngoko, isiphumo sokusetyenziswa kunye nobomi benkonzo yokuthwala zihambelana kakhulu nokuchaneka kunye nobulukhuni bebhola yentsimbi ethweleyo. Yobulukhuni ukuzala ibhola sentsimbi inxulumene nexabiso umthwalo umthwalo kwibhola yentsimbi.

Emva kokuhlanjwa ngokuchanekileyo, ukuthambisa ioyile nangaphambi kokupakisha iibhola zesampulu kwibhetshi zithunyelwa ukuphicothwa okokugqibela ukujonga uburhabaxa bomhlaba, ukujikeleza, ukuvuka, umahluko wobungakanani beqashiso nobulukhuni kwilabhoratri ephucukileyo, ngokweendlela zokulawula ezichaziweyo kunye neenkqubo zophicotho lwedokodo. Nje ukuba zonke iimfuno zifezekiswe, isatifikethi sovavanyo siyalungiselelwa umthengi. Ilabhoratri yethu ephucukileyo ixhotyiswe ngokuchaneka okuphezulu, oomatshini abahlonitshwayo kwihlabathi liphela kunye nezixhobo kwaye ilawulwa ngabasebenzi abaqeqeshiweyo nabafanelekileyo.
