P235GH thiab P355GH yog European tus qauv (EN 10028) normalized, zoo -grain steels siv rau siab hlab ntsha thiab boilers, sib txawv feem ntau nyob rau hauv lub zog.: P235GHmuaj qhov tsawg kawg nkaus lub zog ntawm 235 MPa (rau cov seem thinner), thaum P355GHmuaj zog dua, nrog lub zog tawm los ntawm 315-355 MPa, ua rau nws haum rau siab dua - cov ntawv thov siab uas yuav tsum tau ua kom zoo dua ntawm qhov kub thiab txias. Ob leeg yog carbon / low-alloy steels nrog zoo weldability thiab formability, tab sis P355GH muab cov cuab yeej kho kom zoo rau kev xav tau kev lag luam.
