FAQ
EN 10305-1 E255 yog dab tsi thiab tus lej txhais li cas?
E255 (cov ntaub ntawv naj npawb 1.0408) yog ib qho tsis yog - alloy zoo hlau rau txias kos seamless precision raj raws li EN 10305-1: 2016. Qhov "255" yog qhov tsawg kawg nkaus lub zog tawm los nyob rau hauv qhov normalized (+N) mob - 255 MPa (37,000 psi). Tib lub raj hauv qhov kev ntxhov siab (+ SR) nce mus txog 375 MPa, yog li lub npe cuam tshuam tsuas yog ib qho ntawm nws lub xeev xa khoom.
Puas yog E255 tib yam li St45?
Yog lawm. E255 thiab St45 yog tib yam hlau raws li cov khoom siv 1.0408. St45 yog lub npe qub DIN 2391; E255 yog tam sim no EN 10305-1 kev xaiv. Lawv sib koom tib yam chemistry thiab tib yam normalized 255 MPa tawm los. Siv St45 thaum sib piv cov duab qub, thiab sau E255 / 1.0408 ntawm kev txiav txim tshiab kom daim ntawv pov thawj phim cov qauv tam sim no.
Vim li cas E255 qhia ob lub zog tawm los, 255 MPa thiab 375 MPa?
Vim tias qhov kev tawm los nyob ntawm qhov kev xa khoom, tsis yog qib ib leeg. Nyob rau hauv lub normalized (+N) yam tsawg kawg nkaus sab sauv tawm yog 255 MPa; nyob rau hauv qhov kev ntxhov siab-relieved (+SR) mob nws yog 375 MPa - 120 MPa qhov sib txawv los ntawm kev ua haujlwm txias ntxiv rau kev ntxhov siab. Tsim kom muaj nuj nqis ntawm qhov xwm txheej koj tau xaj. A + SR raj nqa txog 47% siab dua ntawm tib phab ntsa, lossis xav tau 32% tsawg phab ntsa rau tib lub siab.
Qhov kev xa khoom twg kuv yuav tsum xaiv rau E255 precision raj?
Xaiv los ntawm dab tsi lub raj nkag mus tom ntej. Welded lossis khoov qhov chaw thiab hydraulic chim feem ntau yog siv + SR (375 MPa, qhov ntev ruaj khov, zoo weldability). Cov khoom uas tsis yog- hnyav lossis hnyav hnyav tuaj yeem siv +N (255 MPa, tus nqi qis tshaj). +C thiab + LC yog rau qhov chaw uas nyob raws li - kos thiab tsis welded. +A yog rau kev siv lub tshuab hnyav uas softness pab tswj nti.
Dab tsi yog qhov ntev thiab kam rau ua ntawm E255 precision raj?
EN 10305-1 npog OD 4–380 mm (0.16–14.96 hauv) thiab phab ntsa thickness 0.5–25 mm (0.020–0.98 hauv). Phab ntsa kam rau ua yog ± 10% lossis ± 0.1 hli, qhov twg ntau dua. Kev kam rau sab nraud yog muab los ntawm ISO 7606 chav kawm 7/8/9. Kev Ncaj Ncees tsawg dua lossis sib npaug rau 0.0015 × ntev rau ReH Tsawg dua lossis sib npaug rau 500 MPa. Bright (+ A / + N) qhov chaw ncav cuag Ra Tsawg dua lossis sib npaug li 1.6 µm.
Puas yog E255 sib npaug rau ASTM A519 1020?
Kwv yees li, los ntawm lub zog band, tab sis tsis zoo tib yam hauv chemistry. ASTM A519 1020 (C 0.18–0.23 %, Mn 0.30–0.60 %) zaum hauv tib qhov kev tawm los ntawm E255, tsis tau E255 tso cai Mn 0.40–1.10 %. Rau ib qho kev nyiam-rau-zoo li hloov pauv paub meej tias cov manganese thiab cov khoom xa tuaj, thiab tsis txhob xav tias cov ntawv pov thawj tuaj yeem hloov pauv yam tsis tau kuaj xyuas qhov kev txiav txim spec.
Daim ntawv pov thawj dab tsi thiab tsis yog -kev kuaj kev puas tsuaj tuaj nrog E255 raj?
Txhua qhov kev txiav txim xa nrog EN 10204 3.1 daim ntawv pov thawj tshuaj ntsuam xyuas cov cua sov thiab cov lej pov tseg. Kev tshuaj ntsuam xyuas qhov ntev raws li EN ISO 10893-2 (dhau tam sim no, qib E3), EN ISO 10893-3 (flux to, qib F3) lossis EN ISO 10893-10 (ultrasonic, qib U3B). Kev tshuaj xyuas thib peb muaj nyob rau ntawm kev thov.
E255 puas tuaj yeem muab siab dua 380 hli sab nraud txoj kab uas hla?
TS EN 10305-1 scopes seamless txias drawn precision raj mus txog 380 mm OD. Rau txoj kab uas hla loj dua txoj hauv kev yog tus qauv sib txawv - EN 10297-1 (cov tshuab raj) lossis EN 10305-4 rau cov tshuab hydraulic thiab pneumatic, qhov E255 yog nkag rau hauv + N mob nkaus xwb. Qhia daim ntawv thov kom lub zeb hais cov ntawv pov thawj tseeb.
