Q235NH Corrosion-Resistant Structural Steel - Kev daws teeb meem hauv tsev

Gnee Steel (Tianjin) Co., Ltd. yog ib qho ntawm cov kws tshaj lij q235nh corrosion-resistant structural steel - tsev daws teeb meem manufacturers thiab lwm tus neeg nyob hauv Suav teb. Txais tos rau kev lag luam wholesale customized q235nh corrosion-resistant structural steel - tsev daws teeb meem ntawm tus nqi sib tw los ntawm peb lub hoobkas. Cov kev pabcuam zoo thiab cov khoom zoo yog muaj.

Q235NH corrosion-resistant structural steel yog ib qho kev ua si- hloov pauv hauv kev lag luam hauv tsev, muab kev sib xyaw ua haujlwm zoo thiab ua haujlwm tau zoo.

Tshuaj muaj pes tsawg leeg

Q235NH muaj qhov sib npaug sib npaug ntawm cov ntsiab lus. Cov pa roj carbon (C Tsawg dua lossis sib npaug li 0.12%) ua kom muaj zog txaus thaum tuav cov qauv zoo. Silicon (Si 0.15 - 0.40%) txhim kho cov hlau oxidation tsis kam. Manganese (Mn 0.20 - 0.50%) txhim kho lub zog thiab tawv. Phosphorus (P Tsawg dua lossis sib npaug li 0.035%) thiab sulfur (S Tsawg dua lossis sib npaug li 0.035%) raug txwv los tiv thaiv brittleness. Copper (Cu 0.25 - 0.55%), chromium (Cr 0.30 - 1.25%), and nickel (Ni<=0.65%) form a dense and adherent protective layer on the surface, which significantly enhances corrosion resistance.

Mechanical Properties

Cov hlau no muaj lub zog tawm los ntawm 235 MPa, muab kev thauj khoom zoo heev - cov kabmob muaj peev xwm. Lub zog tensile yog li ntawm 360 - 510 MPa, kom ntseeg tau tias tsis kam mus deformation nyob rau hauv kev ntxhov siab. Nws muaj qhov elongation tsawg kawg yog 26%, uas qhia tau hais tias zoo ductility rau ntau yam txheej txheem fabrication.

Cov yam ntxwv tseem ceeb

Exceptional Corrosion Resistance: Nws tuaj yeem tiv taus huab cua hnyav, xws li kev lag luam muaj kuab paug, cov tshuaj tsuag ntsev ntawm ntug dej hiav txwv, thiab cov av noo siab, txo cov nqi tu lub sijhawm ntev.

Siab zog: Muaj peev xwm txhawb nqa hnyav, ua kom haum rau loj - scale kev tsim kho.

Weldability zoo: Yuav tau yooj yim welded siv txoj kev vuam siv, yooj yim rau kev tsim kho.

Lub neej ua haujlwm ntev: Ua kom lub sijhawm ntev - ruaj khov thiab kev nyab xeeb ntawm cov tsev.

Daim ntawv thov

Lub tsev tsim: Zoo tagnrho rau kev tsim kho siab - nce vaj tse, txuas hniav, thiab cov tsev khaws khoom lag luam.

Infrastructure Projects: Siv hauv kev tsim cov chaw nres nkoj, chaw nres tsheb ciav hlau, thiab chaw ntau pob.

Architectural Facades: Ntxiv ib qho kev zoo nkauj kov thaum muab cov qauv kev ncaj ncees.
