StE355 steel phaj yog cov khoom siv hlau siv rau boiler thiab cov hlab ntsha siab. DIN17102 StE355 siab hlab ntsha steel phaj muaj zoo lis thiab txhua yam khoom. DIN17102 StE355 steel phaj yog tus yam ntxwv los ntawm qhov tsawg kawg nkaus lub zog ntawm 295-335 MPa thiab zoo weldability. Yog li ntawd, StE355 steel phaj yog tsuas yog siv nyob rau hauv kev tsim cov boilers, siab hlab ntsha thiab kav rau thauj cov kua kub.
