ASTM A514 qib P 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 P 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). Ib daim ntawv qhia tag nrho txhais tau tias qhov no yog tus nqi siab tshaj plaws hauv cov teeb meem cuam tshuam. Ib nrab-tag nrho bar txhais tau tias nws yog 50% ntawm qhov siab tshaj, thiab lwm yam.
Steel phaj A514 Qib P yog nyob rau hauv steel qauv specification rau siab yield zog ASTM A514/A514M.A514GrP yog alloy steel phaj nrog quenching thiab tempering kub kho thaum dov.Muaj cov qib steel zoo li SA514 Qib P hauv steel qauv ASME SA 514 / SA 514M.Thaum xa khoom steel cov ntaub ntawv ASTM A514Gr.P, steel zeb yuav muab daim ntawv pov thawj zeb xeem, kuj luv luv raws li MTC uas qhia txog qhov tseem ceeb ntawm cov tshuaj muaj pes tsawg leeg, cov cuab yeej cuab tam, tag nrho cov txiaj ntsig thaum dov ntawm steel A514 Qib P.
