I-Carbon Stebon Stebon Steets inomxholo wekhabhoni phakathi kwe-0.60- 1.25%. I-Storbon Stebon Steels ye-allows inomxholo we-manganese kuluhlu lwe-0.30 - 0.90%. Kuwo onke amabakala amathathu, i-carbon yekhabhoni ephezulu yentsimbi inobuqili kunye nobunzima obuphezulu ngelixa bubonisa eyona nto iphantsi. Ukungaxhathisi okuphezulu kuvela kwinto yokuba ezi zikrikhi ziphantse zalukhuni kwaye zinomvuzo.
I-bolts ye-carbon ye-carbon, i-anchor bolts, isikali, izitya, amantongomane kunye ne-screlling kunye ne-0.25-0.65% ye-manganese ngobunzima. Iipropathi zoomatshini kwezi ziqwenga ziphuculwe ngonyango lobushushu.
Akukho zinto zahlukeneyo-zisetyenziswe njengearhente yolwabiwo, hayi ezinye iintlobo zensimbi, eyenza amandongomane awaziwa njengee-bolts zexabiso eliphantsi. I-carbon ye-carbon steel kunye namanqanaba e-bolt zahlulwe zangamacandelo amathathu ahlukeneyo ngokusekwe kumxholo wekhabhoni we-carbon ye-Cild, ephakathi kunye nekhabhoni ephezulu.
