ASTM A514 Tsawg-alloy Tus Hlau Qauv Hlau Qib B
Taw qhia
Alloy steels yog tsim los ntawm AISI plaub-lej lej. Lawv suav ntau hom kev sib txawv ntawm cov hlau uas dhau ntawm cov kev txwv ntawm Mn, C, Mo, Si, Ni, Va, thiab B teeb rau cov hlau tsis xwm yeem. Lawv teb tau sai dua rau kev kho tshuab thiab kev kho kub dua li cov pa roj carbon hlau.
Cov ntaub ntawv hauv qab no yuav tham txog txhua yam txog AISI A514 qib B alloy steel, uas muaj cov khoom muaj zog siab.
