P355N steel hlau

P335N siab nkoj steel phaj muaj qhov tsawg kawg nkaus taw tes ntawm 355 Mpa rau lub thickness hauv qab no 16 hli. Gnee steel muaj peev xwm muab P355N steel phaj thickness ntawm 6mm-300mm rau lav cov cuab yeej steel hauv tshuaj muaj pes tsawg leeg thiab cov cuab yeej siv tshuab. Rau lub sijhawm xa khoom ntawm 1000 tons xaj p355n steel daim hlau, peb lub sijhawm dov dav dav yuav tsum tsis pub dhau 30 hnub.
