ASTM A516 vs A36, A572, Q355: Xaiv Cov Phaj Hlau Zoo Rau Kev Tsim Kho Niaj Hnub

Raws li kev lag luam kev tsim kho txuas ntxiv mus, kev xaiv cov phaj hlau zoo rau cov haujlwm tsim kho yog qhov tseem ceeb dua puas tau.ASTM A516 hlau phaj, uas paub dav tias yog cov hlau carbon siv rau hauv cov hlab siab, tab tom nce siab hauv kev siv hauv kev tsim kho vim nws lub zog siab, weldability zoo heev, thiab kev ua haujlwm qis-kub. Tab sis nws piv rau lwm cov hlau siv feem ntau zoo li casASTM A36 hlau phaj , ASTM A572 hlau phaj, thiab Tuam Tshoj cov ntawv hlau Q355?

Kev Ua Haujlwm thiab Lub Zog

ASTM A516 (Qib 60-70) muaj lub zog tawm los ntawm 260–290 MPa thiab lub zog tensile txog li 550 MPa, ua ke nrog kev tawv zoo dua thaum kub qis txog -45 ° C. Piv rau:

ASTM A36- Lub zog tawm los 250 MPa, tensile 400–550 MPa, kev ua haujlwm kub qis.

ASTM A572 (Gr.50)- Tawm los ntawm 345 MPa, tensile 450–620 MPa, weldability zoo heev thiab toughness qis-kub.

Q355- Cov qoob loo 355 MPa, tensile 470–630 MPa, siv dav hauv cov haujlwm tsim kho hauv Suav teb rau nws lub zog siab thiab ruaj khov.

Qhov no ua rau A516 zoo tagnrho rau cov nqaj hlau hnyav, cov phaj kawg ntawm tus choj, thiab cov khoom siv hauv cov chaw txias.

Cov Ntawv Thov Kev Tsim Kho Ib Txwm Muaj

Hlau Cov ntawv thov
ASTM A516 Cov phaj thauj khoom, cov khoom siv choj, cov qauv kub qis, cov khoom txhawb nqa siab
A36 Cov nqaj txheem, cov kem, thiab cov thav duab yooj yim
A572 Cov tsev siab siab, cov nroj tsuag kev lag luam, cov choj, cov qauv tiv taus huab cua
Q355 Cov tsev lag luam, cov tsev rau khoom, cov choj, cov phaj thauj khoom

Kev Ua Haujlwm thiab Kev Sib Txuas Lus

A516 qhov kev sib txuas zoo heev thiab kev ua tau zoo ua rau nws ua tau zoo li cov phaj tuab, cov pob qij txha vuam, thiab cov khoom siv ruaj khov. A36 yooj yim rau kev ua tab sis tsis haum rau kev siv hnyav lossis ntev. A572 thiab Q355 muab lub zog siab tab sis xav tau kev tswj hwm vuam ceev faj rau cov ntu tuab.

Xaiv Cov Hlau Zoo

Rau cov haujlwm tsim kho niaj hnub no, cov kws ua vaj tse xav txog ASTM A516 ntau zuj zus thaum cov khoom siv hauv tsev xav tau ob qho tib si lub zog thiab kev ua haujlwm kub qis. Rau cov qauv tsev dav dav, A36 tseem yog qhov kev xaiv pheej yig. Lub caij no, A572 thiab Q355 yog qhov nyiam rau cov qauv siab, choj, thiab cov tsev lag luam uas lub zog siab thiab kev ruaj khov yog qhov tseem ceeb.

Thaum cov qauv kev tsim kho nce siab thoob ntiaj teb, kev nkag siab txog qhov sib txawv me me ntawm cov qib hlau yog qhov tseem ceeb los txhim kho kev nyab xeeb, tus nqi, thiab kev ua tau zoo hauv txhua qhov project.
