Khoom Description
A516 Qib 70 phaj yog nplua-cov hlau uas muaj cov pa roj carbon (C), manganese (Mn), silicon (Si), phosphorus (P), sulfur (S), thiab trace grain-refining ntsiab xws li niobium (Nb) thiab vanadium (V). Piv nrog rau lwm cov pa roj carbon steel, nws muaj cov ntsiab lus ntawm cov pa roj carbon monoxide thiab cov ntsiab lus siab manganese. Qhov no muaj pes tsawg leeg muab siab zog thiab toughness thaum tuav zoo weldability.
A516 Qib 70 nthuav tawm qhov tsawg kawg nkaus lub zog ntawm kwv yees li 260 MPa thiab lub zog tensile yam tsawg kawg nkaus ntawm 485-620 MPa, xa cov kev ua tau zoo tag nrho zoo dua rau cov qauv carbon steel. Qhov tseem ceeb, nws cov yas thiab cov tawv tawv tseem nyob ruaj khov txawm tias nyob hauv cov phaj tuab, ua rau nws zoo tagnrho rau kev tsim cov khoom loj - txoj kab uas hla, tuab - phab ntsa siab hlab ntsha.
Txawm hais tias nyob rau hauv petrochemical cia thiab tsheb thauj mus los, cov cuab yeej siv hluav taws xob, lossis kev tsim boiler, nws ua rau muaj kev nyab xeeb ntawm kev lag luam tseem ceeb nrog nws txoj haujlwm ruaj khov thiab txhim khu kev qha. Yog tias koj cov cuab yeej xav tau no steel phaj,nyem lub pob hauv qab notiv tauj peb!

A516 Gr70 tuav lub zog cuam tshuam Ntau dua lossis sib npaug rau 20J ntawm -45℃. Ntawm -30 degree, nws qhov cuam tshuam nqus lub zog tseem tsis muaj tsawg dua 34J, txo qhov kev pheej hmoo ntawm qis{14}}kub nkig tawg. Hauv qhov sib piv, qhov sib npaug GB tus qauv Q345R muaj qhov ntsuas kub tsuas yog -20℃rau +475 degree, pom qhov qis qis dua-kub toughness. Txawm hais tias qhov zoo sib xws qis -kub-taw qhia txog 16MnDR phaj muaj qhov ntsuas qhov ntsuas qhov tsawg kawg nkaus ntawm -40℃thiab pom tias muaj kev ruaj ntseg tsis zoo thiab sib xws hauv qhov ntsuas kub tsis tshua muaj qhov ua tau zoo piv rau A516 Gr70. Qhov kom zoo dua no ua rau nws daim ntawv thov nyob rau hauv cov hlab ntsha uas tsis tshua muaj siab xws li LNG cia tso tsheb hlau luam thiab cov roj liquefied roj tso tsheb hlau luam hauv cov cheeb tsam txias.
Tsim los nrog qhov sib npaug ntawm cov pa roj carbon tsawg (qhov siab tshaj plaws cov ntsiab lus tsawg dua lossis sib npaug li 0.31%), cov hlau no ua rau txo qis kev sib tsoo. Nws txhawb ntau yam txheej txheem vuam xws li MIG, TIG, thiab submerged arc vuam, tsuas yog xav tau ntau dua lossis sib npaug rau 10℃preheating-deb qis dua cov qauv rau qee qhov qis- alloy lossis cua sov-cov hlau tsis muaj zog. Thaum tshav kub kub-cov hlau tiv taus zoo li SA387, muaj cov hlau alloy siab dua, yuav tsum tsis yog siab dua preheating kub thaum lub sij hawm vuam tab sis kuj nyuaj post-weld stress relief treatments. Thaum lub teb chaws Suav tus qauv Q345R yog weldable, nws cov weld zoo stability thiab kam rau siab rau qhov tsis xws luag yog inferior rau A516 Gr70 nyob rau hauv tuab phaj vuam los yog complex structural daim ntaub ntawv.
A516 Gr70 tuav ASME ntawv pov thawj thiab tau lees paub los ntawm cuaj pawg koom haum suav nrog DNV thiab ABS. Nws muaj qhov tshwj xeeb thoob ntiaj teb siv tau rau hauv petrochemical, marine, thiab offshore engineering sectors, ua rau nws tsim tshwj xeeb rau kev tsim khoom tsim khoom. Kev tsim khoom ua raws li cov qauv ntsuas ultrasonic nrog kev tswj xyuas nruj, ua kom muaj kev ua haujlwm ruaj khov. Nws txaus siab rau kev lees paub siab thiab yoog raws hauv cov haujlwm thoob ntiaj teb.
Raws li cov pa roj carbon steel phaj, A516Gr70 tau txais txiaj ntsig los ntawm cov txheej txheem tsim khoom loj thiab ib qho chaw zoo- tsim cov saw hlau, ua rau cov nqi qis dua piv rau qis- alloy thiab siab - alloy siab nkoj steels. Thaum piv rau SA537CL1-ob qho tib si haum rau nruab nrab- kev siv siab-A516Gr70 tshem tawm qhov xav tau kev kho cua sov ua kom muaj zog, yog li txo cov nqi tsim khoom. Tus nqi kom zoo dua yuav qhia tau ntau dua thaum piv rau stainless hlau lossis Cr-Mo alloy daim hlau (xws li, SA387). Ib txhij, nws lub zog dhau ntawm cov pa roj carbon zoo tib yam Q245R, ua kom muaj kev sib npaug zoo ntawm lub zog thiab tus nqi hauv nruab nrab - mus rau - cov hlab ntsha tsis tshua muaj siab. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv nruab nrab - mus rau qis qis.
