ASTM A691 EFW Carbon thiab Alloy Steel Yeeb Nkab Thov Cov Khoom Siv Tau thiab Qhov Yooj Yim
▔▔▔▔
Cov Ntawv Thov:Tsim los rau high - kub, siab {{{}}}}}}}} cov tshuab hluav taws xob thermal thiab tshuab thauj khoom.
Cov yeeb nkab cov khoom tshwj xeeb:
A.) Kev pab txheem txheem them cov yeeb nkab nrog cov kab txaij sab nraud ntau dua lossis sib luag rau 16 ntiv tes (405 hli tuab tsawg dua lossis sib luag rau 3 nti (75 hli). Lwm qhov ntau thiab tsawg yuav tsum tau ua tiav cov kev xav tau sib npaug.
B.) Cov ntaub ntawv suav nrog cov hlau thiab chromium- molybdenum alloy steel (tsim los ntawm hluav taws xob vuam nrog qhov sib ntxiv ntawm cov muab tubtiv hlau.
Cov txheej txheem yooj yim: Kev kho cua sov thaum lub sijhawm tsim khoom yog xaiv tau tab sis yuav tsum txiav txim siab raws li lub hom phiaj cov khoom siv lossis cov lus qhia tshwj xeeb.
