A36 ERW Welded Carbon Steel Yeeb Nkab

Lub ntsiab tivthaiv ntawm A36 hluav taws xob tsis kam welded yeeb nkab yog hlau (Fe), muaj cov pa roj carbon (C) thiab alloying ntsiab silicon (Si), manganese (Mn), thiab lwm yam. Ntawm lawv, cov ntsiab lus carbon tsawg, txog 0 .22%-0.28%, uas ua rau A36 steel phaj muaj zoo toughness thiab plasticity. Nyob rau tib lub sijhawm, qhov sib ntxiv ntawm silicon thiab manganese txhim kho lub zog thiab hardness ntawm steel phaj. Cov ntsiab lus ntawm silicon yog hais txog 0.10%-0.40%, thiab cov ntsiab lus ntawm manganese yog li 0.70%-1.10%. Tsis tas li ntawd, A36 steel phaj kuj muaj me me ntawm impurity ntsiab xws li phosphorus thiab sulfur. Cov ntsiab lus ntawm cov ntsiab lus no tsawg thiab muaj kev cuam tshuam me ntsis rau kev ua haujlwm ntawm cov hlau phaj.
A36 ERW Carbon Steel Pipes muaj kev ua tau zoo thiab tuaj yeem ua tiav los ntawm kev tig, milling, drilling, npaj, sib tsoo thiab lwm yam kev ua haujlwm, thiab yooj yim rau kev ua cov txheej txheem xws li kub txiav thiab txias dabtsi yog khoov.
Vim nws cov ntsiab lus tsis tshua muaj carbon, A36 steel yeeb nkab muaj qhov zoo weldability thiab tsis yooj yim rau qhov tsis xws luag xws li tawg, pores, thiab slag suav nrog thaum vuam.
Tom qab kev kho cua sov kom zoo, A36 Hluav taws xob fusion welded yeeb nkab tuaj yeem tau txais lub zog zoo dua thiab tawv. Nws lub zog tensile feem ntau yog 270MPa-500MPa, lub zog tawm los feem ntau yog 180MPa-300MPa, thiab qhov hardness feem ntau yog 85-185HBW.
