Galvanized Welded Hlau Yeeb Nkab Q355B

Q355B galvanized welded yeeb nkab yog tsim los ntawm low-alloy high-strength carbon steel daim hlau thiab ces undergoes galvanization. Feem ntau, Q355B steel kav muaj lub zog siab thiab tiv taus corrosion. Txawm li cas los xij, rau engineering tej yaam num thiab kev thauj mus los ib puag ncig uas yuav tsum tau siab, nto galvanization yog tsim nyog los tiv thaiv corrosion ntawm Q355B welded kav thiab txuas lub neej kev pab cuam ntawm Q355B steel kav.

Vim li cas thiaj xaiv Q355B Steel?

Q355B: Cov khoom lag luam sib xyaw ua ke thoob ntiaj teb

Kev hloov kho ntawm Q345B steel yog qhov tseem ceeb ntawm GB / T 1591-2018 tus qauv tshiab. Kev taw qhia ntawm qib tshiab Q355B qhia txog nws qhov zoo sib xws rau European tus qauv EN 10025's S355JR los ntawm nws lub npe nws tus kheej.

Optimization ntawm Chemical Composition

Qhov kev sib raug zoo no tau cuam tshuam tsis tau tsuas yog nyob rau hauv qib qeb tab sis kuj nyob rau hauv cov tshuaj muaj pes tsawg leeg thiab txhua yam khoom. Piv txwv li, qhov txwv sab sauv ntawm cov ntsiab lus carbon tau nce los ntawm Tsawg dua lossis sib npaug rau {{0}}.20 txog 0.24, sib piv JR qib ntawm European tus qauv, thiab cov khoom tsis zoo xws li Cu tau khaws cia raws li ua raws li qhov ua tau nrog tus qauv European.

Hloov maj mam hloov hauv Mechanical Properties

Nyob rau hauv cov nqe lus ntawm txhua yam khoom, lub zog tawm los ntawm Q355B steel tau nce los ntawm ntau dua los yog sib npaug rau 345 MPa rau Q345B rau ntau dua lossis sib npaug rau 355 MPa. Tsis tas li ntawd, qhov tseem ceeb ntawm lub zog qis zog (ReL) tau hloov mus rau lub zog siab zog (ReH) cov qauv, raws li European qauv. Qhov kev hloov pauv no muaj kev cuam tshuam tsawg heev rau kev tsim khoom thiab kev siv thiab tuaj yeem suav tias tsis cuam tshuam rau kev tsim qauv thiab xaiv cov khoom siv.

Lub hom phiaj tseem ceeb ntawm kev hloov pauv tus nqi tawm los yog kom muaj kev sib haum xeeb nrog cov qauv European, txhim kho cov khoom sib hloov thiab txo cov nqi cuam tshuam nrog kev hloov pauv tsim.
