SMA400BW thiab SMA400AP yog ob qho tib si JIS G 3114: 2022- ntawv pov thawj Corten Steel qib, tsim los rau kev siv sab nraum zoov-tab sis lawv tsis hloov pauv. Lawv qhov sib txawv me ntsis tseem ceeb yog nyob rau hauv kev sib xyaw alloy, kev ua tau zoo, thiab kev siv zoo tagnrho, ua rau ib qho zoo dua rau cov haujlwm tshwj xeeb tshaj li lwm qhov. Kev xaiv qib tsis raug tuaj yeem ua rau cov nqi tsis tsim nyog, txo kev ua haujlwm ntev, lossis dhau - specification-yog li kev nkag siab txog lawv cov kev sib txawv tseem ceeb yog qhov tseem ceeb rau txoj haujlwm ua tiav.
Hauv qab no yog qhov tseeb, lub teeb yuag ntawm qhov sib txawv ntawm qhov tseem ceeb ntawm SMA400BW thiab SMA400AP, hauv paus hauv JIS cov qauv, nrog rau cov lus qhia siv tau los pab koj xaiv qib zoo.
Core Difference 1: Chemical Composition (JIS G 3114: 2022 Mandated)
Qhov sib txawv loj tshaj plaws ntawm ob qib yog lawv cov xim pleev xim hlau -tshwj xeeb cov ntsiab lus nickel- uas ua rau lawv cov corrosion kuj thiab toughness:
SMA400AP: Nickel-dawb (Ni Tsawg dua lossis sib npaug li 0.03% ib JIS). Nws cov core corrosion- sib ntaus sib tua alloys yog tooj liab (Cu: 0.30–0.50%) thiab chromium (Cr: 0.45–0.75%), nrog cov pa roj carbon tsawg (tsawg dua lossis sib npaug li 0.18%) rau weldability.
SMA400BW: Muaj cov nickel tswj (Ni: 0.05-0.30% ib JIS). Nws qhia tib yam Cu thiab Cr ntau yam li SMA400AP, tab sis cov npib tsib xee ntxiv txhim kho patina stability thiab qis - kub toughness.
Ob qib muaj qhov txwv tsis pub muaj qhov sib npaug (P Tsawg dua lossis sib npaug rau 0.035%, S Tsawg dua lossis sib npaug li 0.035%) kom ntseeg tau tias muaj kev sib koom ua ke thiab kev ua haujlwm zoo.
Core Difference 2: Impact Toughness & Environmental Adaptability
Ua tsaug rau nws cov ntsiab lus nickel, SMA400BW outperforms SMA400AP nyob rau hauv cov huab cua txias thiab ntub ib puag ncig, thaum ob leeg ua tau raws li JIS tej yam toughness qauv rau lawv npaj siv:
SMA400AP: Yam tsawg kawg nkaus toughness ntawm 27J ntawm 0℃(Charpy V-notch test). Haum rau cov huab cua me me, qhov chaw sov uas qhov kub tsis tshua poob qis hauv qab khov.
SMA400BW: Tsis tas li 27J yam tsawg kawg nkaus ntawm 0 degree, tab sis nws cov ntsiab lus npib tsib xee txhim kho patina uniformity thiab tsis kam rau cov av noo. Nws ua tau zoo dua hauv cov huab cua sov nrog lub caij ntuj no txias thiab cov av noo ntau dua.
Core Difference 3: Cov Kev Siv Zoo Tshaj Plaws (Practical Value Focus)
Lawv qhov sib txawv ntawm qhov sib txawv txhais mus rau qhov sib txawv ntawm kev siv- xaiv cov qib zoo ua kom koj tau txais tus nqi zoo tshaj:
SMA400AP: Qhov zoo tshaj plaws rau qhov sov, qhuav, lossis qis- ib puag ncig cov av noo (piv txwv li, thaj chaw nyob deb nroog, thaj chaw sov ntawm ntug dej hiav txwv Loj dua lossis sib npaug li 1km ntawm ntug dej). Qhov zoo tshaj plaws rau cov qauv sab nraum zoov yooj yim xws li cov canopies me me, kev txhawb nqa hluav taws xob, thiab qis -kev tu vaj tse.
SMA400BW: Zoo dua rau cov huab cua sov nrog lub caij ntuj no txias, cov av noo siab, lossis lub teeb muaj kuab paug. Zoo meej rau cov neeg taug kev txuas hniav, lub tsev thav duab, thiab cov txheej txheem nthuav tawm uas xav tau ntau dua patina thiab txias - huab cua kev ntseeg siab.
Qhov Tseem Ceeb Similarities (Dab Tsi Lawv Qhia)
Nws tseem yog ib qho tseem ceeb kom nco ntsoov lawv qhov zoo sib xws, uas ua rau ob qho kev xaiv txhim khu kev qha rau txoj haujlwm zoo:
Zoo tib yam txhua yam muaj zog: Yield zog (215-245 MPa), tensile zog (400-510 MPa), thiab elongation (Ntau tshaj los yog sib npaug rau 26%).
Weldability zoo heev: Cov ntsiab lus carbon tsawg tso cai rau cov txheej txheem vuam (SMAW, GMAW) uas tsis muaj kev tshwj xeeb ua ntej - cua sov rau feem ntau thicknesses.
Atmospheric corrosion kuj: Ob daim ntawv tiv thaiv patinas, nrog rau txhua xyoo corrosion ntawm 0.01-0.05 hli / xyoo nyob rau hauv ib puag ncig me me.
Yuav ua li cas xaiv ntawm lawv
Ib txoj cai yooj yim ntawm tus ntiv tes xoo rau cov tswv yim xaiv hom:
Xaiv SMA400AP yog tias koj qhov project nyob hauv huab cua sov, qhuav thiab yuav tsum muaj kev tiv thaiv corrosion yooj yim- nws cov npib tsib xee- cov khoom tsis pub dawb ua rau nws raug nqi ntau dua - zoo.
Xaiv SMA400BW yog tias koj qhov project ntsib lub caij ntuj no txias, cov av noo siab, lossis lub teeb pom kev ua qias tuaj - nws cov ntsiab lus nickel muab kev ruaj ntseg zoo dua thiab kev thaj yeeb ntawm lub siab.
Nyob rau hauv luv luv, SMA400BW thiab SMA400AP yog ob qho tib si txhim khu kev qha JIS G 3114: 2022 Corten Steel qib, tab sis lawv cov ntsiab lus npib tsib xee thiab ib puag ncig adaptability muab lawv sib nrug. Kev nkag siab txog qhov sib txawv tseem ceeb no ua rau koj xaiv cov qib uas haum rau koj qhov project huab cua thiab kev xav tau- zam kev pov tseg thiab ua kom ntev tshaj - lub sij hawm tus nqi.
