Lub thickness ntau ntawm Q235NH Corten Steel ncaj qha txhais nws qhov kev siv tau rau hauv cov haujlwm engineering hauv pej xeem-los ntawm nyias daim hlau rau cov hniav cladding mus rau cov ntawv tuab rau kev thauj khoom- cov kabmob txhawb nqa. Rau engineers, buyers, thiab fabricators, qhia meej txog cov txheej txheem muab thickness yog ib qho tseem ceeb rau qhov project tsim, tswj nqi, thiab kev npaj yuav khoom. Dab tsi yog qhov tuab tuab rau cov qauv khoom ntawm Q235NH? Raws li GB / T 4171 tus qauv thiab kev coj ua lag luam thoob ntiaj teb, cov ntsiab lus tseem ceeb yog qhov tseeb:Q235NH Corten Steel feem ntau yog muab nyob rau hauv ib lub thickness ntawm 3 hli mus rau 50 hli rau cov qauv txiav txim, nrog rau kev ncua ntau yam (txog 90 hli) muaj nyob rau ntawm customized ntau lawm, tag nrho raws li Suav zoo qauv.. Hauv qab no yog ib qho yooj yim, kev txiav txim siab tawg.
Cov ntsiab lus tseem ceeb: Cov Khoom Siv Txheej Txheem Thickness & GB / T 4171 Kev Ua Raws Cai
Q235NH tus qauv tuab ntau yog tswj hwm los ntawm GB / T 4171 《Weathering structural steels express, kom ntseeg tau tias muaj kev sib luag thoob plaws cov tuam txhab thiab kev sib raug zoo nrog cov txheej txheem ua haujlwm ntau. Tus txheej txheem muab khoom siv yog optimized rau loj ntau lawm thiab universal daim ntawv thov:
Core Standard Range: 3mm mus rau 50mm (kub- dov los yog thermo- tshuab tswj dov, TMCP). Qhov no suav nrog ntau dua 80% ntawm Q235NH daim ntawv thov, suav nrog guardrails, lub tsev facades, me me choj Cheebtsam, thiab cia tank panels.
Dav & Length sib phim: Txheem thicknesses yog khub nrog dav ntawm 1220mm, 1500mm, los yog 2000mm, thiab ntev mus txog 6000mm (customizable). Qhov kev sib xyaw ua ke no txhawb nqa kev txiav thiab sib dhos rau feem ntau cov haujlwm hauv pej xeem.
Quality Assurance: Tag nrho cov qauv thicknesses (3-50mm) tuaj nrog zeb xeem ntawv qhia (MTR) paub meej tias ua raws li GB/T 4171, suav nrog txhua yam khoom thiab corrosion-resistant cov ntsiab lus.
Thickness Subranges & Cov ntawv thov sib xws
Txawv thickness subranges yog tailored rau tej load thiab kev xav tau kev pab, nrog meej tswv yim:
1. Thin Phaj (3mm -16mm): Kho kom zoo nkauj & Teeb-Structure Siv
Qhov tseem ceeb: Zoo heev formability, haum rau txias dabtsi yog khoov, dov, thiab plasma txiav. Cov phaj nyias nyias muaj cov qauv zoo li qub, ua kom cov huab cua tsis sib xws nyob thoob plaws qhov chaw.
Tej kev siv: Sab nraum zoov zoo nkauj cladding, billboard thav duab, lub teeb yuag guardrails, thiab tsis yog -load- bearing phab ntsa panels. Piv txwv li, 6-10mm daim hlau feem ntau yog siv nyob rau hauv cov vaj tse toj roob hauv pes.
2. Cov Phaj Nruab Nrab (16mm-50mm): Load-Bearing & Structure Components
Qhov tseem ceeb: Sib npaug lub zog thiab ductility, ua tau raws li qis - mus rau - nruab nrab qhov yuav tsum tau ua. Cov phaj siab tshaj 20 hli feem ntau siv TMCP工艺 los ua kom cov nplej zom, tsis txhob degradation toughness.
Tej kev siv: Cov choj me me, lub plhaub ntim cia, hnyav -cov haujlwm tiv thaiv cov ncej, thiab steel qauv brackets. 30-50mm daim hlau yog qhov zoo tagnrho rau cov khoom siv thauj khoom zoo li qub (piv txwv li, lub hauv paus tsim tawm sab nraum zoov).
3. Cov phaj tuab (50mm-90mm): Customized Heavy-Duty Scenarios
Qhov tseem ceeb: Muaj tsuas yog los ntawm kev cai kub dov, yuav tsum tau tswj cov txheej txheem nruj (qhib txias, normalization) kom ntseeg tau cov qauv sab hauv. Thicknesses tshaj 50mm tuaj yeem pom qhov poob qis me ntsis hauv qhov muaj zog tawm los (rau ntau dua lossis sib npaug rau 215MPa rau 40-60mm daim hlau) tab sis tseem ua raws li GB / T 4171.
Tej kev siv: Tshwj xeeb thauj khoom-cov kabmob xws li choj piers, cov cuab yeej siv hauv tsev, thiab siab - qhov siab txhawb nqa cov qauv. Cov no yuav tsum tau kuaj ntxiv ntawm -20℃kom paub meej tias muaj zog.
Thickness cuam tshuam rau kev ua haujlwm & kev ua haujlwm
To taub yuav ua li cas thickness cuam tshuam rau Q235NH lub processability pab kom tsis txhob muaj teeb meem ntau lawm:
Vuam: Phaj Tsawg dua lossis sib npaug li 20mm yuav tsum tsis muaj preheating; 20-50mm daim hlau xav tau 80-120℃preheating los tiv thaiv cov kab mob khaub thuas; Cov phaj tuab (＞ 50mm) xav tau tom qab vuam kev nyuaj siab annealing.
Txiav: nyias daim hlau (3-16mm) nplua plasma txiav rau kev ua haujlwm siab; nruab nrab-tuab daim hlau (16-50mm) ua haujlwm nrog nplaim taws; tuab daim hlau (＞50mm) yuav tsum tau optimized nplaim txiav tsis txhob ntug 淬硬.
Huab cua Resistance: Thickness tsis cuam tshuam rau kev tsim patina-txhua qhov sib txawv tsim cov txheej tiv thaiv xeb hauv 1-2 xyoos hauv cov huab cua me me.
Cov tswv yim muab tswv yim & Customization Tips
Standard vs. Custom: Rau tej yaam num nrog lub sij hawm nruj, xaiv cov qauv thicknesses (3-50mm) rau tam sim; customized tuab daim hlau (50-90mm) yuav tsum tau 2-4 lub lis piam ntawm cov khoom txhuas lub sij hawm.
Z-Kev taw qhia kev ua tau zoo: Rau cov phaj tuab (15-60mm) siv hauv cov qauv welded, qhia Z15/Z25/Z35 Z-kev taw qhia cov khoom kom tsis txhob lamellar tearing.
Nqe Lus Cim: Kev cai tuab daim hlau (＞ 50mm) raug nqi 15-25% ntau dua li cov qauv kev ua haujlwm tshwj xeeb, yog li qhov sib npaug thickness xav tau nrog pob nyiaj siv.
Hauv cov ntsiab lus, Q235NH Corten Steel tus qauv muab khoom tuab yog li ntawm 3mm txog 50mm, nrog rau cov kev xaiv customizable mus txog 90mm rau hnyav -lub luag haujlwm xav tau. Txhua qhov thickness subrange ua raws li cov ntawv thov tshwj xeeb thiab cov kev xav tau ua tiav, kom ntseeg tau tias kev ua haujlwm zoo thiab tus nqi -effectiveness. Los ntawm kev xaiv cov tuab tuab raws li kev thauj khoom, kev ua, thiab kev xa khoom xav tau, cov neeg siv tuaj yeem ua kom cov khoom siv tau zoo tshaj plaws hauv cov haujlwm sab nraum zoov.
