ASTM A500 Welded Carbon Steel Tubing Txias - tsim cov lus piav qhia
A500 tus qauv welded yeeb nkab feem ntau yog ua los ntawm cov qauv hlau thiab tsim siv cov txheej txheem txias txias. Raws li ASTM A500 tus qauv, cov kav dej square raug faib ua ntau qib, suav nrog Gr.A, Gr.B, thiab Gr.C, nrog rau qhov sib txawv ntawm qhov muaj zog thiab tensile zog. Piv txwv li, Gr.B qib square kav feem ntau muaj lub zog tawm los ntawm tsis pub tsawg dua 290 MPa thiab lub zog tensile ntawm 400 thiab 550 MPa, ua tau raws li qhov yuav tsum tau muaj ntawm feem ntau lub tsev thav duab thiab kev txhawb nqa tshuab.
ASTM A500 GRA GRB GRC GRD Specification
astm a500 qib yield zog
Qhov tsawg kawg nkaus lub zog rau ASTM A500 Qib A yog 33,000 psi rau puag ncig tubing thiab 39,000 psi rau zoo li tus tubing. Tus nqi no tseem tuaj yeem qhia tau tias yog 228 MPa lossis 269 MPa feem. Nws yog ib qho tseem ceeb uas yuav tsum tau xyuas cov khoom tshwj xeeb kom paub meej tias qhov tsawg kawg nkaus tawm lub zog rau daim ntawv thov thiab cov duab, raws li tus nqi sib txawv ntawm puag ncig thiab zoo li tus tubing.
astm a500 qib b yield zog
Qhov tsawg kawg nkaus tawm lub zog rau ASTM A500 Qib B yog 46,000 psi (315 MPa). Qhov no yog ib qho kev qhia tshwj xeeb rau cov qauv tubing siv hauv kev thauj khoom -cov ntaub ntawv siv kabmob.
astm a500 qib c yield zog
Lub zog tawm los ntawm ASTM A500 Qib C yog 50,000 psi (345 MPa) rau zoo li tus (square thiab rectangular) structural tubing. Rau cov txheej txheem puag ncig, qhov tsawg kawg nkaus tawm lub zog yog 46,000 psi (317 MPa). Qib no muaj lub zog tensile yam tsawg kawg nkaus ntawm 62,000 psi (425 MPa).
astm a500 qib d yield zog
Qhov tsawg kawg nkaus tawm lub zog rau ASTM A500 Qib D yog 36,000 psi (250 MPa). Nws qhov kawg tensile lub zog yog 58,000 psi (400 MPa). Qib D yog qib cua sov- kho, thiab lub zog tawm los siv rau ob qho tib si puag ncig thiab zoo li tus qauv tubing.
