Classification ntawm carbon steel qib qhia txoj kev
Nws muaj Q + tus lej + cim qib zoo + deoxidation txoj kev cim. Nws tus lej steel yog prefixed nrog "Q", uas sawv cev rau lub ntsiab lus ntawm cov hlau. Cov lej hauv qab no sawv cev rau tus nqi taw tes tawm hauv MPa. Piv txwv li, Q235 sawv cev rau carbon structural steel nrog rau qhov taw tes tawm (σs) ntawm 235 MPa.
Yog tias tsim nyog, cov cim qhia txog qib zoo thiab deoxidation txoj kev tuaj yeem raug cim tom qab tus lej hlau. Cov cim qib zoo yog A, B, C, thiab D raws. Deoxidation txoj kev cim: F sawv cev rau cov hlau boiling; b sawv cev rau semi-tua steel; Z sawv cev rau cov hlau tua; TZ sawv cev tshwj xeeb tua hlau. Cov hlau tua tsis tuaj yeem raug cim nrog cov cim, uas yog, Z thiab TZ yuav tsis raug cim. Piv txwv li, Q235-AF sawv cev rau qib A boiling steel.
Tshwj xeeb-lub hom phiaj carbon steel, xws li choj hlau, marine steel, thiab lwm yam, yeej siv cov qauv sawv cev ntawm cov qauv steel, tab sis ib tsab ntawv qhia lub hom phiaj yog ntxiv rau qhov kawg ntawm cov hlau tooj.
