Dab tsi yog qhovSIB 36siv rau?
ntawm no zoo nkaus li muaj kev tsis meej pem me ntsis hauv lub rooj sib tham lub npe.
Tsis muaj kev lees paub dav dav lossis qauv hlau qib hu ua "SA36." Nws yog qhov yuav luag tsis raug sau lossis luv luv rau cov qauv hlau "ASTM A36" (lossis qee zaum, tsawg dua, "ASME SA-36" specification, uas yog technically tib yam khoom tab sis tswj hwm los ntawm American Society of Mechanical Engineers code).
Piv txwv tias koj tab tom xa mus rau ASTM A36 / ASME SA-36, ntawm no yog cov lus piav qhia ntxaws txog qhov nws siv rau.
ASTM A36 / SA-36 yog dab tsi?
Nws yog cov qauv carbon steel uas txhais los ntawm ASTM International (ASTM A36) thiab ASME Boiler thiab Pressure Vessel Code (SA-36). Nws yog lub hom phiaj dav dav tshaj plaws ntawm cov qauv hlau hauv Tebchaws Meskas, Canada, thiab ntau thaj chaw raws li Asmeskas cov qauv.
Cov yam ntxwv tseem ceeb:
Lub zog: Yam tsawg kawg nkaus lub zog ntawm 36,000 psi (250 MPa).
Kev sib xyaw: Nws muaj cov ntsiab lus carbon txog li 0.29%, uas siab dua nws cov European counterpart S235, ua rau nws me ntsis weldable tab sis muaj zog heev thiab formable.
Philosophy: Nws yog feem ntau yog "kev ua tau zoo-raws li" specification, txhais tau tias nws lav cov khoom siv kho tshuab (lub zog, elongation) ua ntej, nrog rau cov tshuaj muaj pes tsawg leeg txwv tsis pub dhau thiab dav.
ASTM A36 / SA-36 siv rau dab tsi? (Cov ntawv thov)
Nws qhov sib npaug zoo ntawm lub zog, ductility, yooj yim ntawm fabrication, thiab tus nqi qis ua rau nws "workhorse" steel rau ntau yam kev siv:
1. Kev tsim vaj tsev thiab kev tsim vaj tse (feem ntau siv)
Structure Framing: Beams (I-beams, wide-}flange), kem, channels, and angles for business, industrial, and home buildings.
Txuas hniav: Rau phaj girders, hla -thav duab, thiab ntau yam kev txhawb nqa (feem ntau hauv cov qhab nia tau raws li qhov yuav tsum tau muaj zog ntxiv).
Transmission Towers & Utility Ncej.
Staircases, Walkways, thiab Balconies.
2. General Fabrication thiab Manufacturing
Cov Khoom Siv Hnyav: Lub hauv paus ncej, chassis, thiab kev txhawb nqa rau kev ua liaj ua teb, kev tsim kho, thiab cov tshuab mining.
Muaj Platforms & Mezzanines: Flooring, racks, thiab kev txhawb nqa cov qauv hauv factories thiab warehouses.
Machine Parts: Brackets, gears, daim hlau, thiab shafts qhov twg siab zog tsis yog thawj qhov kev txhawj xeeb, tab sis zoo machinability yog.
Forgings thiab Stampings: Siv los ua khoom noj rau cov khoom uas kub - forged rau hauv cov duab.
3. Kev thauj mus los
Truck Chassis thiab Trailers: Ncej rails thiab structural Cheebtsam.
Shipbuilding: Rau qhov tsis yog- tseem ceeb, cov qauv hauv dej hauv av thiab cov thav duab sab hauv (marine- cov qib tshwj xeeb yog siv rau cov nkoj).
Railroad Tsheb: Cheebtsam zoo li sab ncej thiab bolsters.
4. Ntau yam qauv
Kos npe txhawb nqa thiab lub teeb ncej.
Agricultural Cia Silos thiab Khoom Siv.
Art thiab Sculpture: Txaus siab los ntawm cov kws kos duab hlau rau nws yooj yim ntawm vuam thiab sib sau.
Cov ntsiab lus
ASTM A36 / SA-36 yog qhov tseem ceeb, mus rau cov qauv hlau rau kev tsim kho thiab tsim khoom thoob plaws North America thiab dhau mus. Yog tias koj pom cov qauv hlau, cov khoom siv, lossis cov khoom tsim uas tsis yog tshwj xeeb rau cov xwm txheej huab cua, muaj qhov tshwm sim ntau heev uas nws yog tsim los ntawm A36 steel. Nws txoj kev siv universal yog ib qho pov thawj rau nws qhov kev ua tau zoo thiab kev lag luam muaj nqis.
Tag nrho cov specification thiab cov ntsiab lus muaj nyob rau ntawm kev thov. Cov ntaub ntawv saum toj no yog muab rau kev taw qhia nkaus xwb. Rau cov qauv tsim tshwj xeeb thov hu rau peb cov neeg ua haujlwm muag khoom.
