SMA400BW Corten Steel yog ib qho tseem ceeb atmospheric corrosion- qib resistant nyob rau hauv JIS G 3114: 2022 tus qauv, engineered rau welded sab nraum zoov structural daim ntaub ntawv uas txhim khu kev qha lub zog, huab cua kev ua tau zoo thiab qis -kub durability intersect. Thaum nws poob rau hauv SMA400 series ntawm Corten Steels, nws qib - cov kev qhia tshwj xeeb tau teeb tsa nws sib nrug rau cov txheej txheem siv cov teeb pom kev zoo - ua rau nws mus - rau kev xaiv rau tej yaam num uas xav tau kev ua tau zoo nyob rau hauv qhov sib txawv sab nraum zoov. Cov lus qhia no rhuav tshem SMA400BW tus cwj pwm tseem ceeb, JIS-tswj cov khoom thiab lub hom phiaj tsim qauv, tag nrho cov ntsiab lus meej, ua tau zoo rau cov haujlwm ua haujlwm.
Core txhais: SMA400BW hauv JIS G 3114: 2022
Raws li JIS G 3114: 2022- tau ntawv pov thawj qis-alloy Corten Steel, SMA400BW tau muab cais uaweldable atmospheric corrosion-cov qauv steeltsim tshwj xeeb rau liab qab lossis pleev xim rau sab nraum zoov siv. Nws qhov "BW" qib kev xaiv ua raws li JIS G 3114: 2022's grading system, qhia tias nws tau ua kom zoo rau cov qauv siv dav dav nrog kev tsom mus rau qhov sib npaug ntawm kev tiv thaiv corrosion, txhua yam muaj zog thiab kev yooj yim fabrication - tsis muaj kev tshwj xeeb alloy boosts rau huab ib puag ncig, tsuas yog ua raws, tus qauv - ua raws li kev ua haujlwm sab nraum zoov.
Tsis zoo li lwm yam SMA400 variants, SMA400BW yog tus qauv tsim kom xa cov khoom sib xws thoob plaws cov qauv tuab (txog 100mm), nrog rau JIS nruj tswj ntawm cov ntsiab lus alloy thiab impurities kom ntseeg tau batch- rau-batch sib xws rau cov haujlwm thoob ntiaj teb.
Qhov tseem ceeb JIS G 3114: 2022 Mandated Core Properties
SMA400BW qhov kev ua tau zoo yog kaw los ntawm JIS G 3114: 2022 tsis yog -cov lus qhia tshwj xeeb, suav nrog cov tshuaj lom neeg muaj pes tsawg leeg thiab cov khoom siv kho tshuab uas txhais tau tias nws cov qauv thiab corrosion- muaj peev xwm tiv taus:
Chemical Composition (wt%) - Corrosion & Weldability Foundation
C Tsawg dua lossis sib npaug li 0.18%: Tsawg carbon rau zoo weldability, tshem tawm cov cua sov- cuam tshuam cheeb tsam brittleness
0.30-0.50%, Cr 0.45-0.75%: Core corrosion- sib ntaus sib tua alloys kom ruaj khov patina tsim
Ni tsawg dua lossis sib npaug li 0.30%: Cov ntsiab lus npib tsib xee coj los txhim kho patina stability nyob rau hauv ib puag ncig me me / kev lag luam
P Tsawg dua lossis sib npaug rau 0.035%, S Tsawg dua lossis sib npaug rau 0.035%: Tight impurity caps tiv thaiv pitting, vuam tsis xws luag thiab lamellar tearing
Mechanical Properties – Structural Reliability
Yield zog215-245 MPa (thickness -nyob; 245 MPa rau Tsawg dua lossis sib npaug rau 16 hli, 215 MPa rau 40-100mm)
Tensile zogQhov siab: 400-510 MPa
Elongation Ntau dua lossis sib npaug li 26-27%: High ductility rau txias forming thiab kev cai structural profileing
Impact Toughness: Ntau dua los yog sib npaug rau 27 J ntawm 0℃(Charpy V-notch test) - tiv taus cov pob txha tawg hauv qhov chaw txias
Tag nrho cov khoom yog Hoobkas- sim ib JIS raws tu qauv, nrog rau Mill Test Report (MTR) muab rau txhua batch kom paub meej tias ua raws.
Dab tsi ua SMA400BW Cim hauv SMA400 Series?
Tsis pub dhau JIS G 3114: 2022's SMA400 Corten Steel lineup, SMA400BW yogntau yam mainstream qib- tawm tsam qhov sib npaug ntawm qhov nkag - theem SMA400AP (nickel- dawb, rau cov xwm txheej nruab nrab) thiab tshwj xeeb SMA400CW (txhim kho rau qis- qhov kub thiab txias). Qhov tseem ceeb sib txawv:
Nws muaj kev ruaj ntseg zoo dua patina dua SMA400AP (ua tsaug rau kev tswj Ni cov ntsiab lus) rau me me ntug dej hiav txwv / chaw lag luam
Nws yog tus nqi ntau dua -zoo dua SMA400CW, vim nws tsis xav tau cov hlau hloov kho rau sub-zero kub
Nws khaws tib lub weldability thiab formability li lwm yam SMA400 qib, tsis muaj tshwj xeeb fabrication xav tau kev pab.
Tswv yim Tsim Lub Hom Phiaj & Cov Kev Siv Zoo Tshaj Plaws
JIS G 3114: 2022 tsim SMA400BW raulight-rau- nruab nrab load sab nraum welded qauvqhov twg ntev -lub sij hawm atmospheric corrosion kuj thiab structural kev ntseeg siab tsis yog -negotiable. Nws cov kev siv zoo tagnrho suav nrog:
Cov neeg taug kev txuas hniav, txoj kev loj nyob deb nroog choj railings thiab me me - ncua choj Cheebtsam
Kev lag luam / kev lag luam lub tsev framing (qis- rau- nruab nrab- nce) thiab kev txhawb nqa hluav taws xob sab nraum zoov
Architectural structural ntsiab (canopies, feature kab) thiab toj roob hauv pes qauv
Lub teeb muaj cov cuab yeej siv hauv paus thiab conveyor txhawb nqa nyob rau hauv me me kev lag luam / chaw ntub dej
Tshwj xeeb, SMA400BW yogtsis npajrau siab - raug cov ntug hiav txwv dej hiav txwv (cov tshuaj ntsev ncaj qha), kev tso dej tsis tu ncua, lossis sub- xoom qis- qhov kub thiab txias (tsawg dua lossis sib npaug rau -20 degree)-cov no yuav tsum tau tshwj xeeb Corten Steel qib ib JIS G 3114:2022.
Tus nqi tseem ceeb ntawm SMA400BW rau Cov Qauv Txheej Txheem
SMA400BW lub zog loj tshaj yog nwsstandardized kev ntseeg siab thiab tus nqi -effectivenessrau mainstream sab nraum structural tej yaam num. Raws li JIS G 3114: 2022 core qib, nws muab:
Ntev -lub sij hawm corrosion kuj (0.01–0.05 mm / xyoo corrosion tus nqi) nyob rau hauv cov nyob deb nroog, nroog thiab lub teeb muaj ib puag ncig
Seamless fabrication nrog cov qauv vuam / tsim cov cuab yeej (tsis muaj cov cuab yeej tshwj xeeb)
Kev ua raws cai thoob ntiaj teb (raws li ISO 630-5, Eurocode 3, AS / NZS 3679) los ntawm MTR pov thawj
Cov kev xav tau kev saib xyuas tsawg (xim: repaint txhua 10-15 xyoo; tsis pleev xim: teeb pom kev txhua xyoo)
Nyob rau hauv luv luv, SMA400BW Corten Steel yog JIS G 3114: 2022 tus workhorse atmospheric corrosion-resistant qib-engineered kom zoo ib yam, nqi-kev ua tau zoo nyob rau hauv cov feem ntau cov sab nraum zoov structural project scenarios. Nws cov khoom tsim qauv ua rau nws muaj peev xwm ua tau, code-raws li kev xaiv rau engineers thiab tus tswv qhov project nrhiav kev sib npaug ntawm durability, fabrication yooj yim thiab ntev -lub sij hawm tus nqi.
