Cov Khoom Qhia Txog Khoom

Cov Cim Npe Khoom

ASTM A519 Qib 1020 yog dab tsi?

ASTM A519yog ib lub yeeb nkab hlau tsis muaj qhov txuas rau cov hom phiaj kho tshuab nrog lub cheeb sab nraud tsis pub tshaj 12 3/4 nti (325 hli).

Qib 1020, Qib MT 1020, thiabQib MT X 1020yog peb qib, txhua yam yog cov kav hlau carbon.

Cov Txheej Txheem Tsim Khoom ntawm ASTM A519

ASTM A519 yuav tsum tau tsim los ntawm kev siv cov txheej txheem seamless, uas yog cov khoom tubular tsis muaj welded seams.

Feem ntau cov kav hlau tsis muaj qhov sib txuas yog tsim los ntawm kev ua haujlwm kub. Yog tias xav tau, cov khoom ua haujlwm kub kuj tuaj yeem ua haujlwm txias kom tau txais cov duab, qhov loj me, thiab cov yam ntxwv xav tau.

cov txheej txheem yeeb nkab hlau tsis muaj seamless

ASTM A519 muaj cov duab puag ncig, plaub fab, plaub fab plaub fab, lossis lwm yam duab tshwj xeeb.

Botop Steel tshwj xeeb hauv cov yeeb nkab hlau puag ncig thiab tuaj yeem kho cov duab raws li qhov thov.
