HC420LA hlau

HC420LA steel yog lub zog muaj zog qis-alloy steel nrog cov cuab yeej tshwj xeeb thiab kev siv. Txhawm rau kom nkag siab zoo dua nws cov yam ntxwv thiab kev siv tau zoo, kev sib piv nrog lwm cov qib steel tuaj yeem pab tau zoo.

Ib qho ntawm feem ntau piv cov qib steel yog HC340LA. Piv rau HC340LA, HC420LA feem ntau muaj zog tensile ntau dua. Piv txwv li, thaum HC340LA tuaj yeem muaj lub zog tensile nyob rau hauv thaj tsam ntawm 340 txog 500 MPa, HC420LA tuaj yeem ncav cuag lub zog tensile ntawm 420 txog 560 MPa. Qhov kev muaj zog ntxiv no ua rau HC420LA tsim nyog rau cov ntawv thov ntau dua qhov yuav tsum muaj peev xwm thauj khoom ntau dua.

Lwm qib steel rau kev sib piv yog HC260LA. HC420LA muaj zog ntau dua li HC260LA. HC260LA feem ntau muaj lub zog tensile ntawm ib ncig ntawm 260 txog 380 MPa. Nyob rau hauv cov nqe lus ntawm yield zog ib yam nkaus, HC420LA outperforms HC260LA. Lub zog muaj zog ntau dua ntawm HC420LA txhais tau tias nws tuaj yeem tiv taus kev ntxhov siab ntau dua ua ntej deformation mus tas li.

Thaum piv rau cov hlau me me, qhov sib txawv yog qhov ntau tshaj. Cov hlau me me feem ntau muaj lub zog tensile qis dua, feem ntau nyob rau hauv thaj tsam ntawm 200 txog 400 MPa. HC420LA lub zog siab tso cai rau nws siv rau hauv cov ntawv thov uas cov hlau me me yuav tsis txaus.

Nyob rau hauv cov nqe lus ntawm ductility, HC420LA tseem tuav ib theem tsim nyog txawm tias nws lub zog siab. Nws muaj qhov elongation ntawm kev tawg uas yog piv rau lwm cov hlau tsis tshua muaj hlau. Piv txwv li, nws yuav muaj elongation ntawm ib ncig ntawm 10% mus rau 15%, uas yog txaus rau ntau txoj kev tsim thiab fabrication txheej txheem.

Hais txog kev siv, HC420LA feem ntau siv hauv kev lag luam tsheb rau cov khoom siv uas yuav tsum muaj zog tsis tau hnyav. Nws tuaj yeem pom nyob rau hauv qhov chaw xws li chassis Cheebtsam, lub cev panels, thiab kev txhawb nqa. Hauv qhov sib piv, cov hlau me me feem ntau yog siv rau kev siv dav dav uas yuav tsum muaj lub zog tsis siab.

HC260LA kuj tseem siv rau hauv kev lag luam tsheb, tab sis rau cov ntawv thov tsis tshua muaj txiaj ntsig lossis qhov kev txuag qhov hnyav tsis yog qhov tseem ceeb. HC340LA, ntawm qhov tod tes, yuav siv tau rau hauv cov ntawv thov uas xav tau qhov sib npaug ntawm lub zog thiab kev tsim.

Hauv kev xaus, kev sib piv ntawm HC420LA nrog rau lwm qib steel xws li HC340LA, HC260LA, thiab cov hlau me me qhia nws cov khoom tshwj xeeb thiab qhov zoo. Kev nkag siab txog qhov sib txawv no tuaj yeem pab cov engineers thiab cov neeg tsim qauv xaiv cov qib steel uas tsim nyog tshaj plaws rau lawv cov kev siv tshwj xeeb, xav txog yam xws li lub zog, ductility, qhov hnyav, thiab tus nqi.
