ASTM A514 qib A steel phaj

ASTM A514 qib A yog ib hom ASTM A514 steel. Cov khoom suav hais tias tsim nyog rau qhov quenched thiab tempered mob. Daim duab tuav ntawm cov khoom siv daim npav hauv qab no piv ASTM A514 qib A rau: wrought alloy steels nyob rau hauv tib qeb (sab saum toj), tag nrho cov hlau alloys (nruab nrab), thiab tag nrho cov ntaub ntawv (hauv qab).

Steel phaj A514 Qib A yog nyob rau hauv steel qauv specification rau siab yield zog ASTM A514/A514M.A514GrA yog alloy steel phaj nrog quenching thiab tempering tshav kub kev kho mob thaum dov.A514 Qib A yog lub siab zog steel phaj nrog tsawg kawg nkaus yield zog ntawm 690Mpa rau lub thickness hauv qab 65 hli, thiab 620 Mpa rau lub thickness saum toj no 65 hli, lub zog tensile yuav tsum nyob rau hauv 760-895 Mpa. Cov chaw tsim khoom tuaj yeem rov kho cov phiaj xwm uas ua tsis tau raws li cov cuab yeej cuab tam ntawm qhov kev qhia tshwj xeeb no thaum dov ntawm siab nruj steel phaj A514GrA.Tag nrho cov cuab yeej cuab tam yuav tsum tau rov ua dua thaum cov khoom raug xa rov qab rau kev tshuaj xyuas.

Cov cuab yeej cuab tam rau A514GrA alloy steel:
Tshuaj muaj pes tsawg leeg rau A514GrA alloy steel (Kub ntsuas Max%)
