Thaum nws los txog rau kev tsim thiab kev siv cov qauv, kev xaiv cov khoom siv yog ib qho tseem ceeb los xyuas kom muaj kev ruaj ntseg, durability, thiab kev ua tau zoo. Ib yam khoom uas muaj kev hwm heev hauv kev lag luam yog ASTM A252 Qib 3 steel. Qhov kev qhia tshwj xeeb no yog qhov tseem ceeb tshwj xeeb rau kev tsim cov yeeb nkab piles siv hauv cov hauv paus tob, ua rau lawv yog ib qho tseem ceeb hauv ntau yam kev tsim kho.
ASTM A252 yog tus qauv kev qhia tshwj xeeb tsim los ntawm American Society for Testing and Materials (ASTM) uas qhia txog qhov yuav tsum tau ua rau welded thiab seamlesscev steelpawg. Qib 3 yog qib siab tshaj plaws nyob rau hauv qhov kev qhia tshwj xeeb no, nrog qhov tsawg kawg nkaus tawm lub zog ntawm 50,000 psi (345 MPa). Qhov no ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum tau muaj peev xwm ua haujlwm siab thiab ua haujlwm rau deformation.
Ib qho ntawm qhov zoo ntawm ASTM A252 Qib 3 yog nws cov weldability zoo heev, uas tso cai rau kev tsim khoom thiab kev teeb tsa zoo. Cov tshuaj muaj pes tsawg leeg ntawm cov hlau no suav nrog cov ntsiab lus xws li carbon, manganese, thiab silicon, uas ua rau nws lub zog thiab tawv. Tsis tas li ntawd, cov khoom siv tuaj yeem tiv taus ib puag ncig hnyav, ua rau nws tsim nyog siv rau hauv marine thiab lwm qhov chaw nyuaj.
Qhov tseeb, ASTM A252 Qib 3 feem ntau yog siv rau hauv kev tsim cov choj, cov tsev, thiab lwm yam kev tsim kho vaj tse uas yuav tsum muaj kev sib sib zog nqus. Nws lub peev xwm los txhawb nqa cov khoom hnyav thaum tuav cov txheej txheem kev ncaj ncees yog qhov tseem ceeb rau lub neej ntev thiab kev nyab xeeb ntawm cov qauv no.
Hauv cov ntsiab lus,ASTM A252 Qib 3steel yog cov khoom siv tseem ceeb rau kev tsim kho kev lag luam, muab lub zog thiab kav ntev uas yuav tsum tau siv rau kev siv lub hauv paus tob. Kev nkag siab txog nws cov yam ntxwv thiab cov txiaj ntsig tuaj yeem pab cov engineers thiab cov neeg cog lus paub txog kev txiav txim siab thaum xaiv cov khoom siv rau lawv cov haujlwm, thaum kawg ua rau muaj kev nyab xeeb thiab txhim khu kev qha.
