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).
Puas yog A36 tib yam li carbon steel?
Tsis yog, A36 tsis zoo ib yam li "carbon steel" hauv kev nkag siab dav dav. Hloov chaw, A36 yog ayam tshwj xeebntawm carbon steel.
"Carbon steel" yog ib pawg dav (xws li "SUV").
A36 yog qib tshwj xeeb thiab cov lus qhia tshwj xeeb hauv pawg ntawd (xws li "Ford Explorer").
Kev piav qhia ntxaws:
1. "Carbon Steel" yog dab tsi?
"Carbon steel" yog ib tsev neeg ntawm cov hlau uas lub ntsiab alloying yog cov pa roj carbon, tsuas yog txwv tsis pub lwm cov ntsiab lus (xws li manganese, silicon, thiab tooj liab). Nws feem ntau muab faib ua peb pawg - pawg:
Tsawg Carbon Steel (Mild Steel): ~ 0.05-0.25% carbon. Feem ntau, ductile, yooj yim tsim thiab welded. A36 poob ntawm no.
Cov pa roj carbon nruab nrab: ~ 0.25-0.60% carbon. Muaj zog tab sis tsis tshua muaj ductile, siv rau shafts, gears.
High Carbon hlau: ~ 0.60-1.0% carbon. Nyuaj heev thiab muaj zog, siv rau cov springs, txiav cov cuab yeej.
Analogy: Dej haus
Cov pa roj carbon steel="Soda"
A36 Steel="Coca-Cola"
1040 Steel (ib nrab carbon steel)="Ginger Ale"
A516-70 (cov pa roj carbon steel rau cov hlab ntsha siab)="Coke"
Lawv tag nrho cov dej qab zib, tab sis lawv yog cov khoom sib txawv nrog cov zaub mov txawv thiab lub hom phiaj.

Xaus: Hu rau A36 "carbon steel" yog qhov tseeb, tab sis hu tag nrho cov pa roj carbon steel "A36" yog qhov tsis raug. A36 yog ib qho ntawm feem ntau thiab dav muajyam tshwj xeebntawm structural carbon steel.
