Qhov sib txawv tseem ceeb yog tensile thiab yield zog.
A516 Gr60: Tensile Strength 415-550 MPa, Yield Strength Ntau dua lossis sib npaug li 220 MPa. Haum rau kev thov tsawg dua, kev siv qis dua.
A516 Gr70: Tensile Strength 485-620 MPa, Yield Strength Ntau dua lossis sib npaug li 260 MPa. Muaj zog thiab tsim nyog rau cov hlab ntsha siab dua xws li LPG cia tank, cov tshuaj reactors loj, thiab boilers.
Yuav xaiv li cas? Yog tias koj tus qauv tsim siab dua lossis koj xav tau phab ntsa nyias kom txuag tau qhov hnyav, xaiv Gr70. Rau cov uas tsis yog- tseem ceeb, qis- cov dej siab lossis cua txais, Gr60 yuav txaus thiab tus nqi qis dua.
Q: 2.Yuav SA516 Gr70 puas siv tau rau kev pabcuam hydrogen?
Yog, tab sis nrog ceev faj.
SA516 Gr70 feem ntau yog siv rau hauv kev pabcuam hydrogen ntawm qhov kub thiab txias (feem ntau qis dua 300℃thiab nruab nrab hydrogen ib nrab siab). Txawm li cas los xij, koj yuav tsum paub txog Hydrogen Induced Cracking (HIC) thiab High Temperature Hydrogen Attack (HTHA) txaus ntshai.
Rau qhov ntub dej H₂S + hydrogen ib puag ncig, koj yuav tsum thov HIC- cov ntawv xeem (peb tuaj yeem muab cov kev xaiv no).
Rau siab -kub hydrogen (siab dua 250 degree), steel nrog ntau alloying ntsiab (xws li Cr-Mo steel zoo li A387 Gr11) yog nyiam.
Peb cov lus pom zoo: Muab koj qhov kev ua haujlwm kub thiab dej hydrogen ib nrab siab, thiab peb yuav pom zoo rau qib zoo.
Q: 3.Koj puas txiav A516GR70 daim hlau rau cov duab kev cai?
Yog, peb ua.
Peb muab kev pabcuam txiav dawb rau qhov me me (plasma lossis nplaim taws txiav). Koj tuaj yeem xaj:
Rectangular shapes (txiav- mus rau - loj los ntawm cov qauv phaj)
Circular rings, gaskets, los yog round blanks
Cov duab tsis zoo (nrog koj daim duab CAD lossis qauv)
Muaj qhov tsawg kawg nkaus txiav txim kom muaj nuj nqis (MOQ) rau cov duab kev cai, feem ntau 5 daim rau ib qho qauv. Thov hu rau peb nrog koj daim duab kos kom sai li sai tau.
