Q1: Dab tsi yog ASTM A36 H-Beam thiab nws txawv li cas ntawm A572 Qib 50 H-Beam?
ASTM A36 H-Beam yog kub- dov cov qauv steel beam nrog qhov tsawg kawg nkaus lub zog ntawm 250 MPa, tsim los rau cov qauv siv dav dav. Piv rau A572 Qib 50 H-Beam, uas muaj lub zog ntau dua ntawm 345 MPa, A36 muaj cov ductility zoo dua thiab tsim tau yooj yim dua, ua rau nws tsim nyog rau cov qauv kev tsim kho uas tsis tas yuav muaj zog ultra- siab zog.
Q2: Cov tshuaj muaj pes tsawg leeg ntawm ASTM A36 H-Beam yog dab tsi?
Cov tshuaj muaj pes tsawg leeg muaj xws li carbon tsawg dua los yog sib npaug rau 0.26%, manganese 0.60-1.20%, phosphorus Tsawg dua los yog sib npaug rau 0.04%, sulfur Tsawg dua los yog sib npaug rau 0.05%, thiab silicon Tsawg dua lossis sib npaug li 0.40%. Cov kev txwv no ua kom muaj qhov sib npaug ntawm qhov sib npaug ntawm kev sib tw, kev sib tw, thiab lub zog ntawm cov qauv. Piv rau A572 Qib 50, A36 feem ntau muaj cov ntsiab lus qis dua me ntsis, uas txhim kho weldability tab sis txo cov khoom siv zog.
Q3: Dab tsi yog cov khoom siv kho tshuab ntawm ASTM A36 H-Beam?
ASTM A36 H-Beam muaj qhov tsawg kawg nkaus lub zog ntawm 250 MPa thiab tensile zog ntawm 400-550 MPa, nrog qhov tsawg kawg nkaus elongation ntawm 20% tshaj 200 mm. Hauv qhov sib piv, A572 Qib 50 kab teeb muaj lub zog ntau dua (345 MPa) tab sis qis dua elongation, muab kev lag luam tawm ntawm lub zog thiab ductility.
Q4: Qhov luaj li cas thiab qhov ntev npaum li cas rau ASTM A36 H-Beam?
Standard qhov ntau thiab tsawg ntawm W4x13 mus rau W44x335, nrog flange thiab web thickness tolerances tswj nyob rau hauv ± 3% thiab siab kam rau ua nyob rau hauv ± 6 hli. Dimensional raug yog qhov tseem ceeb rau kev xa khoom thauj khoom, thiab A36 kab teeb feem ntau ua raws li ASTM kev kam rau siab, uas yog piv rau A572 kab teeb ntawm qhov loj me.
Q5: Puas tuaj yeem ASTM A36 H-Beam tau welded thiab fabricated yooj yim?
Yog lawm. A36 beams yog cov weldable heev siv SMAW, GMAW, los yog FCAW. Preheating feem ntau tsis tas yuav tsum muaj cov tuab hauv qab 50 hli, tsis zoo li qee qhov siab - lub zog steels uas yuav xav tau kev ceev faj tshwj xeeb los tiv thaiv kev tawg. Txias bending, drilling, thiab machining kuj tseem ua tau yam tsis muaj kev kho tshwj xeeb.
Q6: Kev sim ua dab tsi ntawm ASTM A36 H-Beams?
Kev ntsuam xyuas muaj xws li kev sim tensile, kuaj khoov, tshuaj ntsuam xyuas, thiab tshuaj xyuas qhov muag. Mill Test Reports (MTRs) cov ntaub ntawv ua raws li ASTM A36. Tsis yog -kev kuaj kev puas tsuaj (NDT) tuaj yeem siv rau cov haujlwm tseem ceeb. Piv rau A572 kab teeb, A36 kab teeb feem ntau muaj tsawg zog siab - qhov yuav tsum tau ua kom muaj zog.
Q7: Dab tsi yog cov ntawv thov rau ASTM A36 H-Beams?
ASTM A36 H-Beams feem ntau yog siv rau kev tsim lub hauv paus, txuas hniav, cov nroj tsuag kev lag luam, warehouses, thiab cov qauv kev txhawb nqa dav dav. Rau cov ntawv thov uas yuav tsum muaj peev xwm thauj khoom ntau dua, A572 Qib 50 lossis siab dua -qib kab teeb yuav raug xaiv.
Q8: Yuav ua li cas tiv thaiv corrosion rau ASTM A36 H-Beams?
Beams raug xa mus rau hauv zeb tiav, nrog kev xaiv galvanization, pleev xim, lossis txheej rau corrosive ib puag ncig. Kev npaj saum npoo yog qhov tseem ceeb rau kev vuam thiab txheej adhesion. A572 kab teeb kuj tseem yuav xav tau cov txheej txheem, tab sis tuaj yeem ua tau zoo dua hauv - kev ntxhov siab lossis ntev -span qauv vim muaj zog dua.
