A572 Qib 50 Cov Ntaub Ntawv Sib Xws: Koj tuaj yeem siv dab tsi

Nyob rau hauv lub sijhawm ntawm cov khoom siv thoob ntiaj teb, nrhiav cov phiaj xwm kev tsim nyog rau koj cov phiaj xwm yog qhov tseem ceeb {}}} Kev ua tau zoo thaum tsim nyog tus nqi thiab xa khoom.

Nyob hauv lub ntiaj teb engineering thiab kev tsim khoom lag luam,ASTM A572 Qib 50 Siab - muaj zog tsawg {}} alneoy qauv hlauyog qhov kev xaiv zoo tshaj plaws rau choj, vaj tse, thiab khoom hnyav vim nws lub zog hnyav vim nws lub zog zoo tshaj plaws, thiab koj muaj txiaj ntsig zoo- ua hauj lwm zoo

Txawm li cas los xij, vim muab khoom, nqi, lossis qhov sib txawv lossis cov qauv sib txawv, koj yuav xav nrhiav cov ntaub ntawv sib npaug. Kab lus no yuav muab rau hauv - qhov tob saib ntawm cov sib npaug rau 572 gr.50 kom pab koj txiav txim siab paub.

Ua ntej, cia peb soj ntsuam xyuas qhov kev ua haujlwm tseem ceeb ntawm A572 Gr.50, uas yog qhov ntsuas kom txiav txim siab cov khoom sib luag.

• Lub zog cov khoom: nws li tsawg kawg lub zog yog 345 mpa (50 ksi), thiab nws qhov tsawg kawg nkaus tensile lub zog yog 450 mpa (65 ksi).
• Tshuaj lom neeg tshuaj: nws lub zog siab yog feem ntau ua tiav los ntawm microalloying (piv txwv li, ntxiv niobium, vanadium, vanadium {2} {}} kev tswjfwm tswj hwm (TMCP). Cov ntsiab lus carbon cov ntsiab lus yog feem ntau tswj tau tsawg dua lossis sib npaug rau 0.23% los xyuas kom zoo weldability.
• Qhov tseem ceeb ntawm cov hlau: piv rau cov roj carbon steel (piv txwv li, 36), nws lub zog, muaj peev xwm ua haujlwm hnyav thiab cov nqi tsheb thauj mus los. Nws tseem muaj cov muaj kev nyab xeeb zoo thiab qee huab cua tsis kam.

Txawv tebchaws thiab cov cheeb tsam muaj lawv tus kheej cov qauv txheem. Cov hauv qab no yog cov qib uas nyob ze lossis hloov chaw rau A572 Gr.50.

Thov nco tseg: "sib npaug" hauv lub rooj yog lub tswv yim tsim khoom thiab tsis yog. Thaum xaiv lwm cov khoom siv, koj yuav tsum ua tib zoo piv cov tshuaj lom neeg tshuaj lom neeg, cov khoom ntiag tug (tshwj xeeb yog kev lees paub ua kom muaj cua sov), thiab kev lees paub ua cua sov, thiab kev pov thawj kub.

Txhawm rau kom nkag siab zoo dua txoj haujlwm ntawm A572 Gr.50, cov lus hauv qab no sib piv nws nrog A992, lwm cov khoom siv rau peb cov qauv khoom siv.

Lub ASTM A572 gr 50 tshuaj muaj pes tsawg leeg yog qhov zoo rau lub zog thiab weldability:

Lub ASTM A572 Gr 50 cov khoom siv tau muab lub hauv paus muaj zog rau kev siv cov qauv txheej txheem:

Xaiv cov khoom sib npaug tsis yog tsuas yog hais txog qib nrog txuam zog; Koj kuj yuav tsum xav txog cov ntsiab lus tseem ceeb hauv qab no:

Thickness nyhuv:Cov paib uas yuav tsum muaj thiab tensile lub zog tseem ceeb ntawm cov khoom feem ntau txo qis li thickness nce. Kev xaiv cov ntaub ntawv yuav tsum paub meej tias cov khoom ntiag tug ntawm lub hom phiaj tuab sib ntsib qauv tsim.

Kev cai cuam tshuam cov kev xav tau: Lub AVTM A572 G.50 tus qauv nws tus kheej tsis tau muab cov kev xeem Charpy cuam tshuam. Yog tias koj tus qauv yog rau tsawg - qhov kev pab kub (piv txwv li, kev cuam tshuam loj dua, koj yuav tsum sib luag lossis sib luag @ -20 degree).

Vuam thiab Fabrication:A572 Gr.50 muaj qhov tsawg ntawm cov pa hluav taws xob (feem ntau<0.40%), offering good weldability suitable for all conventional welding methods.

Cov neeg tau txais txiaj ntsig yog e70xx koob tshiab electrodes (piv txwv li, E7018) lossis ER70s-6 xaim.

Rau cov daim hlau thicker (feem ntau> 1 hli) lossis qis - vuam, tsim nyog preheating (piv txwv li ntawm 100 degree).

Cov Khoom Siv Ntawv Pov Thawj: Rau cov phiaj xwm tseem ceeb, nco ntsoov tias cov hlau zeb los muab daim ntawv pov thawj ntsuas 3.000 zeb zeb ua raws li tus qauv. Nov yog cov ntaub ntawv tseem ceeb rau kev ua kom tau cov ntaub ntawv ua raws li.

ASTM A572 Qib 50 yog qhov siab- lub zog, qis}} alloy steel nrog cov kev ua tau zoo heev. Qhov kev xaiv ntawm cov khoom sib npaug yog nyob ntawm koj daim ntawv thov tshwj xeeb, cov qauv hauv cheeb tsam, thiab kev ua raws cai.

Cov qhab nia ze tshaj plaws yog feem ntau European S355jr lossis Japanese SM490YA.

Feem ntau piv rau cov qhab nia hauv tsev (hauv Suav teb) yog Q355B, tab sis nco ntsoov nco ntsoov cov kev sib txawv ntawm- Lawv tsis yooj yim.

Tus yuam sij rau kev nkag siab zoo nyob hauv kev nkag siab tob ntawm phiaj xwm kev cai thiab ua tib zoo sib piv ntawm txhua yam kev tsis sib haum xeeb. Tham nrog cov ntaub ntawv tshaj lij kws ua haujlwm lossis tus xa khoom thaum tsim nyog.
