SA36 steel yog ib qho dav 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).
SA36 steel (zoo ib yam li A36) yog ntau yam, dav dav -lub hom phiaj qis- carbon structural steel siv dav hauv kev lag luam uas tsis tas yuav muaj lub zog siab lossis cov khoom tshwj xeeb. Nws cov koob npe yog los ntawm nws qhov zoo weldability, formability, yooj yim ntawm fabrication, thiab nqi -effectiveness.
Nov yog nws cov ntawv thov tseem ceeb
1. Kev tsim kho thiab kev tsim vaj tsev dav dav
Kev Siv Tseem Ceeb: Cov pob txha pob txha ntawm cov tsev lag luam, warehouses, industrial plants, thiab qis - mus rau nruab nrab - cov qauv nce.
Cheebtsam: kab, kab teeb, girders, pem teb joists, ru tsev trusses, thiab lub hauv paus phaj rau txhua kab thiab tshuab.
2. Muaj Fabrication & Machinery
Ncej thiab Kev Txhawb Nqa: Rau cov cav tov, conveyors, platforms, walkways, stairs, thiab railings.
Brackets, Gussets, thiab Mounting Phaj: Tsis yog - qhov tseem ceeb uas yuav tsum tau muaj zog thiab weldability.
Truck Frames, Trailer Beds, thiab Agricultural Equipment Cheebtsam.
3. Infrastructure & Choj ua haujlwm
Tsis yog- cov tswv cuab tseem ceeb hauv cov choj, xws li kev nkag mus rau txoj kev taug kev, kev txhawb nqa brackets, thiab tsis yog - thauj khoom- cov khoom siv bearing.
Faj seeb: Rau lub ntsiab load-cov tswv cuab choj, siab dua - lub zog lossis huab cua steels (zoo li A709) feem ntau tau teev tseg.
4. ASME-Code Pressure Equipment
Nov yog daim ntawv thov tseem ceeb uas "SA36" (tsis yog A36 nkaus xwb) tau qhia meej meej.
Siv rau qhov tsis yog - qhov chaw siab hauv ASME Boiler thiab Pressure Vessel Code kev tsim kho:
Txhawb nqa daim tiab, ceg, thiab brackets rau cov hlab ntsha thiab cov tso tsheb hlau luam.
Lub hauv paus rings, platforms, thiab ntaiv txuas nrog cov hlab ntsha coded.
Structural reinforcement uas tsis tsim lub siab ciam teb nws tus kheej.
5. Lwm yam General Fabrication
Sheet hlau ua hauj lwm, enclosures, thiab guards.
Bolted sib dhos thiab cov khoom siv dav dav.
Vim li cas SA36 raug xaiv rau cov ntawv thov no:
Lub zog txaus: 36 ksi yield zog yog txaus rau ntau yam khoom zoo li qub.
Zoo Weldability & Formability: Tsawg carbon cov ntsiab lus tiv thaiv kev tawg thaum lub sij hawm fabrication.
Nqis -Zoo: Nws yog ib qho ntawm cov hlau uas pheej yig tshaj thiab yooj yim muaj.
Predictable Performance: Raws li cov khoom lag luam tus qauv, nws cov khoom tau zoo - nkag siab.
Qhov twg nws tsis yog siv feem ntau:
Siab -kev ntxhov siab lossis qhov hnyav- cov ntawv thov tseem ceeb (qhov twg HSLA steels zoo li A572 Gr. 50 siv).
Tsawg- qhov kub thiab txias (qhov twg cuam tshuam- cov hlau tawv zoo li A588 lossis A709 yuav tsum tau).
Corrosive ib puag ncig yam tsis muaj kev tiv thaiv (qhov twg weathering steel A606 / A588 los yog stainless hlau yog siv).
Raws li lub siab- khaws cov khoom hauv cov hlab ntsha (qhov twg daim hlau zoo li SA516 yuav tsum tau).
Hauv cov ntsiab lus, SA36 yog qhov tseem ceeb "workhorse" steel rau kev tsim qauv thiab kev tsim kho. Nws siv nyob rau hauv ASME-cov khoom siv coded rau kev txhawb nqa thiab cov ntawv txuas yog qhov laj thawj tshwj xeeb ntawm "SA" ua ntej muaj, qhov txawv ntawm qhov dav dav A36 siv hauv cov tsev.
