Khoom Description
ASTM A516 Gr70 yog tus qauv tsim los ntawm American Society for Testing and Materials (ASTM) los tswj cov khoom siv thiab cov khoom siv ntawm cov pa roj carbon steel. Cov txheej txheem no qhia txog cov tshuaj muaj pes tsawg leeg, cov khoom siv kho mob, kev kho cua sov, kev xav tau hardness, cuam tshuam qhov xav tau, thiab lwm yam ntawm ASTM A516 Gr 70 carbon steel phaj.ASTM A516 Gr 70 specification yog rau lub zog tensile ntawm 485 - 620 MPa. yield zog ntawm qhov tsawg kawg nkaus ntawm 260 MPa.Cov kev ntsuas no ua kom muaj kev ua tau zoo thiab txhim khu kev qha thaum siv. Raws li ASTM A516 Gr 70 steel daim hlau tuaj yeem siv rau ntau yam kev xav tau ua haujlwm.

Khoom zoo
High Pressure Resistance
A516 Gr 70 khav theeb qib siab tshaj plaws nyob rau hauv A516 series, muaj peev xwm tiv taus nruab nrab - mus rau - cov kev kub ntxhov siab thaum tuav ntev - lub sijhawm ua haujlwm ruaj khov yam tsis muaj deformation.
Superior Low-Tsub Toughness
Los ntawm normalizing kev kho mob thiab lwm yam kev ua, cov hlau phaj exhibits zoo heev tiv thaiv nkig tawg nyob rau hauv qis kub, haum rau kev khiav hauj lwm kub ntawm -30℃mus rau 450 degree.
Weldability
Tsim los nrog cov ntsiab lus tsis tshua muaj carbon thiab impurity, A516 Gr 70 daim hlau haum rau cov txheej txheem vuam tseem ceeb xws li SMAW / SAW / GMAW nrog tsawg heev tawg yooj yim.
Kev Ua Raws Cai Thoob Ntiaj Teb
Ua raws li ASTM / ASME / API cov qauv, ua kom siv ncaj qha rau hauv cov khoom xa tawm thiab cov haujlwm txawv teb chaws.
ASTM A516 Gr 70 steel phaj tus me nyuam lub xeev
Thickness tsawg dua 40mm steel phaj:
Lub thickness ntawm steel phaj tsawg dua 40mm default xa hauv lub xeev kub dov. Kub dov lub xeev hais txog cov hlau phaj nyob rau hauv lub kub dov zeb tom qab kub kub thiab dov. Cov phaj hlau no muaj qee qhov muaj zog thiab tawv, muaj feem xyuam rau qhov yuav tsum tau ua kom zoo tsis yog lub sijhawm siab.
Thickness ntau dua los yog sib npaug rau 40mm steel phaj:
Lub thickness ntawm cov hlau phaj yog ntau tshaj 40mm default xa nyob rau hauv normalized mob. Normalizing yog txheej txheem kev kho cua sov los ntawm cua sov cov phaj hlau saum toj no qhov kub thiab txias thiab tom qab ntawd txias hauv huab cua. Qhov no txhim kho tag nrho txhua yam khoom ntawm steel phaj, nrog rau lub zog, toughness thiab weldability.
FAQ
Q: Yuav ua li cas kom zoo?
A: Lub Hoobkas kuaj daim ntawv pov thawj yog muab nrog cov khoom xa tuaj. Yog tias tsim nyog, kev tshuaj xyuas thib peb tuaj yeem lees txais.
Q: Yuav ua li cas txog koj tom qab- kev muag khoom?
A: Raws li lub tuam txhab kev tshaj lij steel export, peb muab kev txhawb nqa thiab kev txhawb nqa rau txhua yam lus nug thiab lus nug.
Q: Dab tsi yog lub siab lub nkoj phaj?
A: PVQ steel phaj yog siv rau kev tsim cov hlab ntsha siab, uas yog kaw cov thawv tsim los tuav cov pa roj lossis cov kua dej ntawm lub siab sib txawv ntau dua li qhov siab.
Q: Dab tsi yog steel siab nkoj?
A: Lub nkoj stainless hlau siab yog ib hom thawv tsim los tuav nws cov ntsiab lus ntawm qhov siab tshaj 15 psig (uas yog 15 phaus ntawm lub zog siv rau ib square inch, txheeb ze rau atmospheric siab). Cov hlab ntsha muaj zog tiv taus kev kub ntxhov, siv sab nraud lossis sab hauv, nrog rau qhov loj ntawm kev nyab xeeb.
Q: Dab tsi qib ntawm steel phaj siv hauv cov hlab ntsha siab?
A: Muaj ntau ntau qib ntawm Pressure Vessel Plate zoo li A537 yog qib feem ntau. Cov qhab nia tsawg dua yuav suav nrog TC128, ASTM A612, thiab ASTM A285. Qhov sib txawv tseem ceeb ntawm Siab Vessel Steel Phaj thiab Corten Steel Phaj yog nyob rau hauv lawv cov tsos.
Q: Dab tsi yog tus qauv hlau rau cov hlab ntsha siab?
A: Thaum muaj ntau qib ntawm PVQ steel, ASTM A516 thiab ASTM A537 feem ntau yog siv rau kev siv lub nkoj siab vim lawv qhov sib npaug ntawm lub zog thiab ductility.
