A671GrCC60Cl32 welded yeeb nkab yog ib hom hluav taws xob tsis kam welded steel yeeb nkab. Cov kav dej welded feem ntau siv cov pa roj carbon steel ua cov khoom siv hauv paus thiab tsim los ntawm cov txheej txheem vuam tshwj xeeb. Thaum lub sij hawm tsim cov txheej txheem, steel daim hlau yog curled thiab ces longitudinally welded siv cov hluav taws xob arc vuam txoj kev los tsim ib tug kaw tubular qauv. Piv nrog rau qee cov kav dej welded, cov txheej txheem tsim khoom ntawm cov khoom siv no tseem ceeb rau kev tswj cov vuam zoo thiab cov khoom siv sib xws los xyuas kom muaj kev ruaj ntseg tag nrho.

| Kev txhais thiab tus qauv kev koom tes | A671 yog ib qho tshwj xeeb ntawm American Society for Testing and Materials (ASTM) rau hluav taws xob tsis kam welded steel kav. GrCC60 qhia cov yam ntxwv ntawm cov hlau cov tshuaj muaj pes tsawg leeg thiab tensile zog. Cl32 sawv cev rau qhov kev ntsuam xyuas cuam tshuam ntawm -32℃thiab ua tiav ntawm cov kev xav tau nruj sib xws. | Tsis tas li ntawd poob raws li ASTM A671 tus qauv rau hluav taws xob tsis kam welded steel kav. GrCC60 zoo ib yam txhais cov yam ntxwv ntawm cov hlau. Cl22 qhia txog qhov kev ntsuam xyuas cuam tshuam ntawm -22℃F (kwv yees li -30 degree, qhov sib txawv ntawm Cl32) thiab ua raws li cov qauv toughness. |
| Impact test kub | -32 degree | -22 ° F (kwv yees -30 ° F) |
| Qhov sib txawv ntawm qhov muaj feem tsawg - qhov kub thiab txias ib puag ncig | Haum rau qhov kub thiab txias (-32 degree) ib puag ncig, tswj kom zoo toughness ntawm tsis tshua muaj kub thiab txo qhov kev pheej hmoo ntawm nkig puas. | Haum rau qhov qis dua - qhov kub thiab txias (ib puag ncig -30 degree) ib puag ncig, kom ntseeg tau qhov kev ua tau zoo ntawm cov yeeb nkab steel hauv qhov ntsuas kub sib xws. |
| Ua kom pom tseeb ntawm daim ntawv thov scenarios | Muaj feem xyuam rau cov xwm txheej uas muaj kev nruj dua qis- qhov yuav tsum tau muaj qhov kub thiab txias, xws li cov cheeb tsam qaum teb thiab cov chaw txhawb nqa rau ultra- qis- qhov kub thiab txias cia. | Muaj feem xyuam rau qhov tsis tshua muaj - qhov kub thiab txias ib puag ncig, xws li roj thiab roj kis tau tus mob nyob rau hauv cov pa qis - qhov kub thiab txias nyob rau sab qaum teb lub caij ntuj no. |
