A Isimbuku sezi elementi zintlanu masingabi ngaphezu kwe-1.00%.

B Ngayo yonke i-0.01% yehla kwi-carbon content, umxholo we-manganese ophezulu uvumelekile ukuba unyuke ngo-0.06%, kodwa ubuninzi abukwazi ukudlula i-1.35%.

C Ukuncipha ngakunye kwe-0.01% kowona mxholo wekhabhoni uphezulu kuya kuvumela owona mxholo uphezulu wemanganese ukuba unyuke nge-0.06%, kodwa ubuninzi bungagqithi kwi-1.65%.
