ASTM A285 Qib A Boiler steel phaj

ASTM A285 tus qauv yog rau carbon steel, qis thiab nruab nrab tensile lub zog steel daim hlau npaj rau fusion-welded siab hlab ntsha.

Cov hlau phaj nyob rau hauv ASTM A285 ntau yam hauv peb qib, A, B thiab C, feem ntau siv yog ASTM A285 Qib C daim hlau.
Uas yuav tsum tau ua los ntawm kev tua, semi-tua, capped lossis rimmed steel kev coj ua ntawm cov chaw tsim khoom xaiv.

Thickness: 6mm-300mm,
Dav: 1500mm txog 4050mm,
Ntev: 3000mm txog 15000mm

ASTM Sandards Cov Lus Qhia:

A20 / A20M: Cov kev cai dav dav rau cov hlau phaj rau cov hlab ntsha siab.

General Requirements thiab Ordering Information:

Kev sim thiab rov ntsuas cov txheej txheem, cov txheej txheem, qhov ntev ntev, qhov loj, zoo thiab kho qhov tsis xws luag, kos npe, thauj khoom thiab xaj cov ntaub ntawv yuav tsum ua raws li A20 / A20M.
Ntxiv rau cov kev cai yooj yim, qee qhov kev xav tau ntxiv muaj.
Cov coils raug cais tawm ntawm A285 mus txog thaum lawv tau txiav rau phaj.
