I-ASTM-SA516Gr60Z35 yokuFumana iFlaw yentsimbi yentsimbi

I-ASTM-SA516Gr60Z35 ukufunyaniswa kwesiphene kwipleyiti yentsimbi:
1. Umgangatho wolawulo we-SA516Gr60: i-ASTM yaseMelika, imigangatho ye-ASME
2. I-SA516Gr60 yeyesitya soxinzelelo lobushushu obuphantsi kunye nepleyiti yensimbi ye-carbon
3. Ukwakhiwa kweekhemikhali ze-SA516Gr60
C≤0.30, Mn: 0.79-1.30, P≤0.035, S: ≤0.035, Si: 0.13-0.45.
4. Iipropati zeMechanical ze-SA516Gr60
I-SA516Gr60 amandla e-tensile angama-70 amawaka eeponti / i-intshi yesikwere, umxholo wento ephambili yi-C Mn Si ps ulawulo lumisela ukusebenza kwayo.Ezinye izinto zokulandelela ngaphantsi.Ukucaciswa koMgangatho we-Asme kwiipleyiti zentsimbi zekhabhoni kwiinqanawa zoxinzelelo oluphakathi kunye noluphantsi lobushushu.
5. Ubume bokuhanjiswa kwe-SA516Gr60
I-SA516Gr60 ipleyiti yentsimbi idla ngokubonelelwa kwimeko yokuqengqeleka, ipleyiti yentsimbi inokuba yesiqhelo okanye isiqabu soxinzelelo, okanye iqheleke kunye nomyalelo wokuphelisa uxinzelelo.
Ubukhulu be-SA516Gr60> 40mm ipleyiti yentsimbi kufuneka ibe yesiqhelo.
Ngaphandle kokuba kuchazwe ngenye indlela ngumceli, ubukhulu bepleyiti yentsimbi ≤1.5in, (40mm), xa kukho iimfuno zobunzima obunotshini, kufuneka buqheleke.
6. I-SA516Gr60 isetyenziselwa ukuvelisa isikhongozeli se-coil ye-welding enye, i-multi-layer hot sleeve coil welding container, i-multi-layer dressing container kunye nezinye iindidi ezimbini kunye nezintathu ze-container kunye ne-low-temperature pressure vessels.Isetyenziswa kakhulu kwi-petroleum, kwishishini lekhemikhali, kwisikhululo samandla, kwibhoyila kunye neminye imisebenzi, esetyenziswa ekwenzeni ii-reactors, i-heat exchangers, izahluli, iitanki ezingqukuva, iitanki ze-oyile kunye nerhasi, iitanki zerhasi enyibilikisiweyo, idrum yebhoyila, iicylinders zepetroleum steam, isikhululo sombane. imibhobho yamanzi yoxinzelelo oluphezulu, i-injini yomoya kunye nezinye izixhobo kunye namacandelo.​
7. Xa i-austenite ipholile ngokukhawuleza (ilingana nokupholisa isithando somlilo, njengoko kuboniswe kwi-Fig. 2 V1), iimveliso zenguqu zisondele kwisakhiwo sokulinganisa, okuyi-pearlite kunye ne-ferrite.Ngokunyuka kwezinga lokupholisa, oko kukuthi, xa i-V3> V2> V1, i-undercooling ye-austenite iyanda ngokuthe ngcembe, kwaye inani le-ferrite ephantsi liba lincinci kwaye lincinci, ngelixa inani le-pearlite likhula ngokuthe ngcembe, kwaye isakhiwo siba ngcono.Ngeli xesha, inani elincinci le-ferrite enqabileyo lisasazwa kakhulu kumda wengqolowa.
8. Ngoko ke, isakhiwo se-v1 yi-ferrite+pearlite;Ubume be-v2 yi-ferrite+sorbite;I-microstructure ye-v3 yi-ferrite+troostite.
