Cov kav hlau tsis muaj qhov txuas ua lub luag haujlwm tseem ceeb hauv kev siv hauv kev lag luam, thiabEN 10210thiab EN 10216 yog ob qho lus qhia dav dav hauv cov qauv European, tsom mus rau cov kav hlau tsis muaj seamless rau kev siv hauv kev tsim kho thiab kev siv siab.

EN 10210 Tus Qauv
Cov khoom siv thiab cov khoom sib xyaw:
LubEN 10210tus qauv siv rau cov kav hlau tsis muaj qhov kub thiab txias rau cov qauv. Cov ntaub ntawv siv feem ntau suav nrog S235JRH, S275J0H,S355J2H, thiab lwm yam. Cov khoom sib xyaw tseem ceeb ntawm cov ntaub ntawv no suav nrog carbon (C), manganese (Mn), silicon (Si), thiab lwm yam. Cov khoom sib xyaw tshwj xeeb sib txawv raws li qib sib txawv. Piv txwv li, cov ntsiab lus carbon ntawm S355J2H tsis pub tshaj 0.22%, thiab cov ntsiab lus manganese yog li 1.6%.

Kev tshuaj xyuas thiab cov khoom tiav lawm:
EN 10210Cov kav hlau yuav tsum tau dhau qhov kev sim khoom siv kho tshuab hnyav, suav nrog lub zog tensile, lub zog tawm thiab kev sim elongation. Tsis tas li ntawd, kev sim kev cuam tshuam toughness yog qhov yuav tsum tau ua kom ntseeg tau tias ua tau zoo hauv qhov chaw kub qis. Cov khoom tiav lawm yuav tsum ua tau raws li qhov kev kam rau siab thiab qhov zoo ntawm qhov chaw teev tseg hauv tus qauv, thiab qhov chaw feem ntau yog xeb-pov thawj.

EN 10216 Tus Qauv
Cov khoom siv thiab cov khoom sib xyaw:
Tus qauv EN 10216 siv rau cov kav hlau tsis muaj qhov sib txuas rau kev siv siab. Cov ntaub ntawv feem ntau suav nrog P235GH, P265GH, 16Mo3, thiab lwm yam. Cov ntaub ntawv no muaj cov khoom sib xyaw sib txawv. Piv txwv li, P235GH muaj cov ntsiab lus carbon tsis pub ntau tshaj 0.16% thiab muaj manganese thiab silicon; 16Mo3 muaj molybdenum (Mo) thiab manganese, thiab muaj kev tiv taus cua sov siab dua.

Kev tshuaj xyuas thiab cov khoom tiav lawm:
Cov kav hlau EN 10216 yuav tsum dhau ntau cov txheej txheem tshuaj xyuas nruj, suav nrog kev tshuaj xyuas cov tshuaj lom neeg, kev sim khoom siv kho tshuab thiab kev sim tsis puas tsuaj (xws li kev sim ultrasonic thiab kev sim X-ray). Cov kav hlau tiav lawm yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm qhov tseeb ntawm qhov ntev thiab kev kam rau siab ntawm phab ntsa, thiab feem ntau xav tau kev sim hydrostatic kom ntseeg tau tias nws muaj kev ntseeg siab hauv qhov chaw siab.

Kev Txheeb Xyuas
LubEN 10210thiab EN 10216 cov qauv rau cov kav hlau tsis muaj qhov sib txuas yog rau cov kav hlau tsim thiab cov kav hlau siab, uas suav nrog cov khoom siv sib txawv thiab cov kev xav tau sib xyaw. Los ntawm kev tshuaj xyuas nruj thiab cov txheej txheem sim, cov khoom siv kho tshuab thiab kev ntseeg tau ntawm cov kav hlau tau ua kom ntseeg tau. Cov qauv no muab lub hauv paus txhim khu kev qha rau kev xaiv cov kav hlau hauv ntau yam kev siv hauv kev lag luam, kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm qhov project.
