ASTM A53 qib A yog qhov tshwj xeeb rau cov roj hlau steel uas siv rau cov qauv kev teeb tsa thiab cov khoom siv tsawg. Nws yog ib feem ntawm ASTM A53 tus qauv, uas suav nrog cov qhab nia sib txawv tsim rau kev siv tshwj xeeb. Cov qib kawm yog paub txog nws qhov sib npaug ntawm cov nqi pheej yig thiab ua tau zoo txaus rau nruab nrab rau cov ntawv thov tsawg.

Tshuaj Muaj Tshuaj

Carbon (c): Mus txog 0. 25%
Manganese (mn): Mus txog 0. 95%
Phosphorus (p): Mus txog 0. 05%
Sulphur (s): Mus txog 0. 045%
Tooj liab, npib tsib xee, chromium, molybdenum, vanadium (tag nrho): Txog li 1. 00%

Cov Khoom Siv Lub Cev

Lub zog tensile: Tsawg kawg yog 330 mpa
Paib lub zog: Tsawg kawg 205 MPa
Elongation: Feem ntau nyob ib ncig ntawm 28%

Cov khoom no ua kom cov neeg nqa khoom tuaj yeem tiv taus qee qib kev ntxhov siab yam tsis muaj kev cuam tshuam lossis tsis ua tiav.

Qib B cov pa roj carbon thiab manganese cov ntsiab lus ua rau muaj zog thiab kav ntev, ua rau nws haum rau cov ntawv thov ntau dua.

Qib B Qhov siab dua lub taub hau thiab tawm kom muaj zog ua rau nws haum ntau rau cov ntawv thov siab.

Nyem Nov"Dab tsi yog ASTM A53 tus qauv"

Cov Ntawv Thov

Kiv dej thiab khoom siv lub tshuab dej: Rau kev xav tau siab qis dua siab.
Cov ntawv thov txheej txheem: Hauv cov qauv tsis-tseem ceeb ntawm cov txheej txheem txhawb nqa.
Neeg kho tshuab tubing: Nyob ntawm Phab Ntsa Thickness thiab Cov Kev Xav Tau Tshwj Xeeb

Qhov Zoo

Nqi zog-ua hauj lwm: Qeb A yog kev lag luam ntau dua rau cov qhab nia siab dua.
Muaj zog txaus: Muab lub zog txaus rau qhov tsawg rau nruab nrab daim ntaub ntawv thov.
Kev Lag Luam Thoob Ntiaj Teb: Ua tus qauv qib, nws tau dav hauv kev ua lag luam

ASTM A53 qib A yog cov pa roj carbon steel tsim rau kev ntsuas siab thiab tsis tseem ceeb. Nws cov tshuaj muaj kuab lom thiab cov khoom siv lub cev ua rau nws muaj txiaj ntsig zoo nqi rau kev siv rau qhov twg siab zog tsis yog qhov kev txhawj xeeb thawj.
