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 wemanganese ukuba unyuke nge-0.06%, kodwa ubuninzi bungagqithi kwi-1.65%.

A Ubuncinane bobude begeyiji yobude obuyi-2in. (50mm) iya kumiselwa ngale fomula ilandelayo:
e=625000(1940)A0.2/U0.9
e = ubuncinane bobude begeyiji 2in. (50mm), ipesenti isondezwe kweyona 0.5% ikufutshane;
A = Kubalwa ngokwe-diameter yangaphandle echaziweyo yetyhubhu yegama okanye ububanzi begama lesampulu ye-tensile kunye nobukhulu bayo obuchaziweyo bodonga, kwaye ijikelezwe kwindawo ekufutshane ye-cross-sectional ye-tensile yesampuli ye-0.01 in.2 (1 mm2), kwaye Ithelekiswa ne-0.75in.2 (500mm2), nokuba yeyiphi encinci.
U = ubuncinci bamandla okuqina, i-psi (MPa).
B Kwiindibaniselwano ezahlukeneyo zobukhulu obahlukeneyo besampulu zovavanyo lwe-tensile kunye namandla amiselweyo amiselweyo, ubuncinane bobude obufunekayo buboniswa kwiTheyibhile X4.1 okanye kwiTheyibhile X4.2, ngokokusebenza kwayo.
Imfuneko yoVavanyo
Uvavanyo lwe-tensile, uvavanyo lokugoba, uvavanyo lwe-hydrostatic, uvavanyo lombane olungonakalisiyo lwe-welds.
