1.What yog ib tug xyoob hlau bar?
Ib tug carbon steel bar yogIb tug alloy uas muaj carbon thiab hlauCov. Nws muaj lub zog siab tensile lub zog thiab cov weldability zoo tab sis tuaj yeem ua rau mob corrosion yog tias tsis kho kom raug. Stainless thiab carbon steel kab muaj cov khoom sib txawv uas ua rau lawv zoo tagnrho rau qee cov ntawv thov.
2.Naib cov hlau muaj zog dua li cov hlau?
Carbon Steel muaj qhov zoo tshaj plaws ntawm cov hlau me me ua rau muaj zog.Carbon Steel tuaj yeem nce txog 20% muaj zog dua li cov hlau me, ua nws ib qho kev xaiv zoo rau high- lub zog thov lossis qhov chaw ua haujlwm siab. Ib qho ntawm qhov tshwm sim tseem ceeb tshaj plaws ntawm cov hlau yog nws tus nqi siab.
3.Yog li cas yog carbon hlau rebar?
Carbon Steel (ASTM A615 / A615M): Qhov no yog hom hlau uas siv rau rebar. Nws yogib cocoy ntawm hlau thiab carbon, nrog rau lwm yamCov. Nws muab lub zog thiab ruaj khov thiab haum rau cov ntawv thov kev siv zog siv tau.
4.IS 304 cov pa roj carbon?
Nws yog ib qho kev siv roj tsis huv, thiab yog yog li ntawd tsis sib nqus. Nws tsis tshua muaj hluav taws xob thiab cuam tshuam cov khoom siv hluav taws xob ntau dua li cov hlau. Nws muaj ntau dua corrosion tsis kam ntau dua li cov hlau tsis tu ncua thiab siv dav vim yog qhov yooj yim nyob rau hauv ntau cov duab {}}} pipes steel.
