SIB 36steel yog ib qho dav - lub hom phiaj carbon structural steel specification txhais los ntawm ASTM International, dav siv rau riveted, bolted, los yog welded kev tsim kho ntawm choj, vaj tse, thiab cov hom phiaj dav dav.
"SA" ua ntej tshwj xeeb qhia tias cov khoom ua tau raws li ASME Boiler thiab Pressure Vessel Code (BPVC) version ntawm ASTM specification, txhais tau tias nws tau txais los siv rau hauv lub nkoj siab thiab boiler kev tsim kho. Rau txhua qhov kev siv tshuab thiab tshuaj lom neeg, SA36 zoo ib yam rau cov feem ntau siv ASTM A36 steel.
Cov yam ntxwv tseem ceeb ntawm SA36 / A36:
Hom: Tsawg- carbon, me ntsis steel.
Tawm Zog: Tsawg kawg 36,000 psi (250 MPa).
Tensile zog: 58, 000 - 80,000 psi (400 - 550 MPa).
Qhov Tseem Ceeb: Nws yog qib "lub zog-tsuas yog" qib. Tsis zoo li ntau qib European (piv txwv li, S355J2), nws tsis muaj qhov yuav tsum tau muaj kev cuam tshuam toughness (Charpy) cov cai hauv nws cov qauv hauv paus.
Weldability: Zoo heev, vim nws cov ntsiab lus carbon tsawg.
Common Forms: Phaj, tuav, cov qauv duab (beams, ces kaum, raws).
Cov ntawv thov raug:
Lub tsev thav duab thiab cov qauv kev lag luam.
Base phaj, tshuab qhov chaw, thiab brackets.
Tsis yog - cov khoom tseem ceeb ntawm cov choj.
General fabrication qhov twg siab zog los yog tsawg -kub toughness tsis yog ib qho kev txhawj xeeb tseem ceeb.
Cheebtsam hauv ASME-cov hlab ntsha siab (thaum teev raws li SA36).
Qhov tseem ceeb Distinction: SA36 vs. A36
ASTM A36: Cov khoom siv tshwj xeeb rau kev siv cov qauv siv dav dav.
ASME SA36: Covzoo ib yamcov khoom siv los ntawm ASME Boiler thiab Pressure Vessel Code. Qhov "S" txhais tau tias nws ua tau raws li ASME cov ntaub ntawv ntxiv thiab cov ntaub ntawv yuav tsum tau siv rau hauv cov khoom siv zog.
Hauv cov ntsiab lus, rau txhua yam khoom siv thiab tshuaj lom neeg, SA36=A36. Lub prefix qhia txog txoj cai tswjfwm rau kev yuav khoom thiab ntawv pov thawj.
International Equivalents (kwv yees):
European: S235JR (EN 10025-2) yog qhov sib tw ze tshaj plaws ntawm cov khoom siv zog (235 MPa nominal) thiab daim ntawv thov dav dav.
Lus Cim Tseem Ceeb: SA36 / A36 tsis muaj qhov sib npaug ncaj qha rau cov qib European zoo li S355 vim qhov sib txawv ntawm lub zog thiab tsis muaj qhov yuav tsum tau ua kom nruj.
Hauv cov ntsiab lus, SA36 yog ntau yam, kev lag luam "workhorse" steel ntawm kev tsim kho thiab kev tsim khoom hauv North America, tau txais txiaj ntsig rau nws qhov yooj yim ntawm fabrication thiab weldability es tsis yog lub zog siab lossis cov khoom tshwj xeeb.
