ASTM A36 steel phaj yog ib qho ntawm cov qib ntau tshaj plaws ntawm cov hlau siv hauv cov ntawv thov kev tsim qauv. Qhov no cov roj carbon steel muaj cov tshuaj xas hlau uas muab cov tshuaj lom neeg xws li kev siv tshuaj ntsuab, ductility uas zoo tagnrho rau kev siv hauv kev tsim muaj ntau yam qauv.
Txheej txheem cej luam:
A36 Steel Phaj yog qib nrov hlau phaj siv rau ntau cov ntawv thov txheej txheem, suav nrog cov tuam tsev.
Muaj rau cov ntawv thov hlau hnyav hnyav hauv txog 18 "tuab.
Tej zaum yuav muaj ntau cov ntawv pov thawj ntawm cov ntawv ceeb toom xeem zeb, tab sis lav tau kom muaj ntawv pov thawj kom tau raws li A36.
Kev Noj Qab Haus Huv Cov Lus Nug ntawm A36 hnyav hlau phaj tau tswj hwm hauv txhua qhov chaw ntawm GNE steel.
Muaj peev xwm ua riveted, bolted lossis welded.
Cov txiaj ntsig ntawm A36 Hlau Phaj
Lub tshuab ua kom muaj zog, lub zog thiab durability ntawm A36 ua rau nws zoo tagnrho rau cov ntawv thov uas xav tau cov ntaub ntawv uas tseem ceeb thiab ruaj khov txaus los tiv thaiv kev ntxhov siab ntau. Cov khoom no yog qhov tseem ceeb heev nyob rau hauv cov ntaub ntawv siv los tsim cov cuab yeej siv hluav taws xob zoo li vaj tse thiab choj, qhov twg ua rau muaj kev puas tsuaj thiab tsis ua txhaum cai.
Vim muaj koob meej ntawm A36 steel phaj, cov phaj hlau phaj nyiam GNEE khaws cov khoom noj qab nyob zoo ntawm cov phaj zoo thiab siv tau yooj yim. A36 tseem yog ib qho ntawm cov qhab nia lag luam tshaj plaws ntawm cov phaj hlau.
A36 Sib npaug Phaj Cov Qib
A36 cov hlau tsim los ua kom tau raws li cov qauv tsim los ntawm ASTM, uas dav tau txais hauv cov phiaj xwm thoob plaws ntiaj teb thoob plaws lub ntiaj teb. Txawm li cas los xij, qee lub tebchaws yuav xav tau cov phiaj xwm kev teeb tsa uas ua tau raws cov qauv teeb tsa los ntawm lub cev tswj txawv. Piv txwv li, cov phiaj xwm kev nyab xeeb uas yuav tsum phaj poob raws S275 nyob rau hauv A36, raws li nws feem ntau suav hais tias sib npaug.
Thaum tsis tau sib npaug rau A36, lwm cov txheej txheem kev teeb meem ntawm cov kab mob me thiab HSLA kuj tseem yuav haum rau hauv cov phiaj xwm hauv tsev, raws li cov qib no muaj cov khoom zoo sib xws rau A36
Daim ntaub ntawv thov & Kev Lag Luam
A36 lub phaj steel yog feem ntau siv rau cov txheej txheem kev thov vim nws lub zog siab ua kom haum A36 rau hauv ntau yam qauv uas tuaj yeem tiv taus cov rog loj. Qee qhov kev siv hluav taws xob sib txawv ntawm A36 suav nrog Choj thiab tsim kho lub tsev.
Thaum feem ntau siv nyob rau hauv lub tsev hluav taws xob, A36 steel phaj ua rau nws zoo tagnrho rau kev siv hauv kev lag luam rau lwm yam kev lag luam thiab, suav nrog:
Kev tsa tsev
Roj thiab roj
Kev lag luam lag luam (hnyav A36 Hlau Hlau)
