Ib qho kev cuam tshuam cov khoom raug txheeb xyuas tsuas yog tias kev xaiv 1.3 tau teev tseg.
b Rau thickness > 3 hli thiab hla-sectional qhov ntev D / T < 15 (round) thiab (B + H) / 2T < 12.5 (square thiab rectangular), qhov tsawg kawg nkaus elongation yog txo los ntawm 2. Rau thickness <3 hli, lub Qhov tsawg kawg nkaus elongation yog 17%.
d Rau thickness <3 hli, saib 9.2.2.
Qhov kev ntsuam xyuas cuam tshuam yuav tsum ua raws li cov cai ntawm EN 10045-1.
Txawm li cas los xij, S235JRH cov raj zoo tsis tas yuav tsum tau kuaj xyuas tus kheej tshwj tsis yog tias muaj cov cai tshwj xeeb.

e Rau kev cuam tshuam cov khoom rau qhov txo qis cov ntawv xeem saib 6.7.2.
TS EN 10219 S235JRH yuav tsum tau xa tuaj rau hauv daim ntawv txias uas tsis muaj kev kho cua sov tom qab, tab sis cov welds yuav nyob rau hauv qhov zoo li-welded lossis kub-kho.
Cold forming yog txheej txheem ntawm kev sib sau mus rau qhov kawg zoo ntawm chav tsev kub.
Rau SAW hollow seem nrog rau sab nraud txoj kab uas hla tshaj 508 hli, yuav tsum tau ua haujlwm kub kub, uas tsis cuam tshuam rau cov khoom siv kho tshuab, kom ua tau raws li qhov yuav tsum tau ua kom ntev ntev.
