Cov khoom sib npaug: Cov tshuaj muaj pes tsawg leeg thiab cov khoom siv kho tshuab ntawm ST37-2 yog qhov tseem ceeb tib yam li S235JR, ua rau lawv hloov pauv tau rau cov hom phiaj siv tau feem ntau [citation: 1, citation: 3].
Weldability: ST37-2/S235JR muaj qhov zoo tshaj plaws weldability vim nws cov ntsiab lus qis, ua rau nws tsim nyog rau kev siv vuam xws li submerged arc vuam (SAW), uas yog cov txheej txheem siv rau LSAW yeeb nkab tsim [citation: 1, citation: 3].
Cov ntsiab lus
Hauv kev xaus,DIN 17100 ST37-2 LSAW yeeb nkabyog ib qho zoo- tsim cov khoom lag luam uas sib txuas cov khoom txhim khu kev qha ntawm ST37-2 cov qauv hlau nrog cov txheej txheem tsim khoom LSAW. Thaum tus qauv German qub tau raug tshem tawm thiab hloov los ntawmTS EN 10025-2 S235JR, ST37-2 tseem yog qib lees paub dav hauv kev lag luam [citation:1, citation:3]. Cov kav dej no feem ntau yog siv rau kev siv cov qauv siv dav dav, lub tsev thav duab, cov hauv paus hauv paus, thiab kev xa cov kua dej tsis zoo [citation: 2, citation: 4]. Rau cov haujlwm tshiab, nws yog qhov zoo tshaj plaws los qhia qhov sib npaug niaj hnub:EN 10025-2 S235JR LSAW yeeb nkab .
