China Material Grades bakeng sa Grey Iron le Ductile Iron

Cast iron ke motsoako oa tšepe oa carbon o nang le karoloana e boima ea carbon e fetang 2.11%. Cast iron e fumanoa ka ho qhibilihisa tšepe ea kolobe ka seboping, ho eketsa ferroalloy, scrap steel, le ho khutlela seboping ho lokisa sebopeho.Tšepe e bohlooho e entsoeng ka tšepe'me tšepe ea ductile ke litšepe tse peli tse sebelisoang ka ho fetisisa bakeng sa ho hlahisa li-castings.

Likarolo tsa tšepe tsa China li hlahisoa haholo ebile li khetholloa ka thepa ea mochini. Sehlopha sa pele sa linomoro sehlopheng se bonts'a matla a fokolang (ho MPa), 'me sehlopha sa bobeli sa linomoro (haeba se le teng) se bontša bolelele bo fokolang nakong ea khefu (%). Lihlopha tse peli tsa linomoro li arotsoe ka dash "-".

Khoutu ea lengolo la Senyesemane ea tšepe e bohlooho ke HT, moo H e leng tlhaku ea pele ea Pinyin ea Sechaena (Hui Se) e bolelang bohlooho; T ke lengolo la pele la Chinese Pinyin (Tie) ea tšepe. Linomoro tsa mephato ea China ea tšepe e putsoa li bonts'a matla a tlase a tensile (MPa). Mohlala, HT250 e emela tšepe e bohlooho e nang le matla a fokolang a 250 MPa.
