Thaum muab S335J0WP Corten Steel rau European- cov phiaj xwm kev lag luam, tshawb xyuas nws txoj kev ua raws li EN 10025-5 (tus qauv tseem ceeb European rau huab cua- cov hlau tsis muaj zog) yog thawj kauj ruam tseem ceeb rau cov neeg yuav khoom. Txawm li cas los xij, ntau tus pom tias nws tsis yooj yim sua kom nrhiav tau qib no hauv cov ntaub ntawv tseem ceeb-ua rau muaj kev tsis ntseeg txog nws txoj cai thiab kev ntseeg tau ntawm kev ua haujlwm. Dab tsi yog cov lus teb meej rau nws txoj kev ua raws EN 10025-5? Cov ntsiab lus tseem ceeb, raws li cov qauv txheej txheem thiab kev coj ua lag luam, yog qhov tseeb:Tsis yog, S335J0WP Corten Steel tsis ua raws EN 10025-5. Hauv qab no yog cov lus qhia luv luv, cov pov thawj -raws li kev txheeb xyuas kom meej meej cov laj thawj thiab muab cov lus qhia ua tau zoo.
Cov ntsiab lus tseem ceeb: EN 10025-5 & Nws Cov Txheej Txheem Corten Steel Qib
Txhawm rau nkag siab tias vim li cas S335J0WP tsis yog- ua raws, peb yuav tsum xub qhia meej txog qhov tseem ceeb ntawm EN 10025-5. Cov qauv no tshwj xeeb tswj hwm atmospheric corrosion-resistant structural steels (ie, Corten Steel) thiab tsuas yog suav nrogstandardized qib nrog meej mechanical thiab tshuaj. Cov qhab nia tshaj plaws hauv EN 10025-5 yog:
Tsawg- zog series: S235J0W, S235J2W
Nruab nrab-strength series: S355J0W, S355J2W, S355J0WP, S355J2WP
Kev soj ntsuam tseem ceeb: EN 10025-5 tsuas yog npog S235 thiab S355 lub zog rau huab cua-cov hlau tsis muaj zog-tsis muaj "S335" pawg zog. Qhov no yog qhov laj thawj tseem ceeb vim li cas S335J0WP tsis tuaj yeem ua raws li tus qauv.
Deep Dive: Vim li cas S335J0WP tsis ua raws EN 10025-5?
Peb tuaj yeem txheeb xyuas qhov tsis yog{0}} ua raws li kev txiav txim siab S335J0WP qib npe (raws li European steel naming conventions) thiab muab piv nrog EN 10025-5 cov kev cai:
"S335" Qib Siab: Raws li tau hais, EN 10025-5 tsuas yog txhais tau tias S235 (yield zog Ntau dua lossis sib npaug rau 235MPa) thiab S355 (yield zog Ntau dua lossis sib npaug li 355MPa) rau huab cua- cov hlau tsis muaj zog. Qib "S335" (hais tawm lub zog muaj zog ~ 335MPa) tsis raug lees paub hauv tus qauv, ua rau qib tsis ua raws.
"J0" Toughness Requirement: "J0" txhais tau tias Charpy V-notch impact toughness tested at 20℃(tsawg zog siab tshaj los yog sib npaug rau 27J), uas yog qib toughness siv tau hauv EN 10025-5. Txawm li cas los xij, txawm tias muaj cov ntsiab lus siv tau, qhov tsis yog -tus qauv "S335" lub zog ua rau tag nrho qib tsis ua raws.
"W" & "P" Suffixes: "W" (weather resistance) thiab "P" (thermo-mechanically dov) yog ob qho tib si siv tau hauv EN 10025-5 (piv txwv li, S355J0WP yog qib txheem). Tab sis ib zaug ntxiv, cov lus xaus no tsis tuaj yeem cuam tshuam qhov tsis yog tus qauv "S335" lub zog.
Kev taw qhia tswv yim rau cov neeg yuav khoom: Yuav ua li cas Hais Txog Tsis yog - Kev Ua Raws Cai
Rau cov haujlwm uas yuav tsum tau ua raws EN 10025-5, cov kauj ruam hauv qab no yog qhov tseem ceeb kom tsis txhob muaj kev pheej hmoo cuam tshuam nrog S335J0WP:
Tshawb xyuas Qib Authenticity: Ua ntej, paub meej nrog cov neeg xa khoom seb "S335J0WP" yog qhov yuam kev typographical (piv txwv li, npaj S355J0WP, tus qauv EN 10025-5 qib) lossis qib kev cai tsis yog qauv. Thov ib daim ntawv teev cov ntaub ntawv ntxaws ntxaws (MDS) kom qhia meej txog tus qauv siv tau.
Xaiv rau Standardized Alternatives: Yog tias EN 10025-5 kev ua raws cai yog qhov yuav tsum tau ua, hloov S335J0WP nrog tus qauv qauv uas haum rau kev ua tau zoo:
Yog tias lub zog nruab nrab (Ntau dua lossis sib npaug rau 355MPa) tau txais: Xaiv S355J0WP (EN 10025-5 ua raws, tib "J0 / W / P" suffixes, lav kev ua tau zoo).
Yog tias lub zog qis dua yog ua tau: Xaiv S235J0W (EN 10025-5 ua raws, tus nqi- zoo rau cov xwm txheej teeb pom kev zoo).
Thov Cov Ntaub Ntawv Ua Raws Cai: Yog tias cov neeg muag khoom tau hais rau S335J0WP, thov daim ntawv pov thawj ua pov thawj nws ua raws li cov qauv tsim nyog (yog tias muaj). Nco ntsoov tias tsis yog -EN 10025-5 qib yuav tsis raug lees txais hauv European-kev ua lag luam tej yaam num lossis los ntawm lub koom haum saib xyuas engineering.
Hauv cov ntsiab lus, S335J0WP Corten Steel tsis ua raws li EN 10025-5, feem ntau vim nws tsis yog tus qauv "S335" lub zog uas tsis tau lees paub hauv tus qauv. Rau txoj haujlwm kev nyab xeeb thiab kev ua raws cai, cov neeg yuav khoom yuav tsum ua ntej tus qauv EN 10025-5 qib (piv txwv li, S355J0WP) lossis tshawb xyuas qhov tseeb ntawm S335J0WP nrog cov neeg muag khoom. Thaum muaj kev tsis ntseeg, xaiv qhov kev lees paub tus qauv qib yog qhov kev xaiv zoo tshaj plaws.
