"Cov ntawv xov xwm" ntawmS890Qmus rau lwm lub teb chaws tus qauv tsis yog ib qho yooj yim 1: 1 sib npaug, tab sis ib tug complex toj roob hauv pes ntawm technical alignment, philosophical sib txawv, thiab nuanced gaps. Kev tshuaj xyuas ntawm qhov sib txawv no yog qhov tseem ceeb rau kev yuav khoom thoob ntiaj teb, kev tsim qauv, thiab kev nyab xeeb.
Ntawm no yog cov ncauj lus kom ntxaws txog seb S890Q (ib EN 10025-6) sib raug zoo li cas thiab txawv ntawm cov qauv hauv lub tebchaws / cheeb tsam loj.
Core Philosophy: EN 10025-6 vs
TS EN 10025-6 (S890Q): Cov khoom siv raws li tus qauv. Nws txhais tau hais tias cov tshuaj muaj pes tsawg leeg thiab ib qho yuav tsum tau quenched & Tempered (Q&T) txheej txheem, tab sis qhov kev lees paub tseem ceeb yog cov txheej txheem ntawm cov khoom siv tshuab (Yield Ntau dua lossis sib npaug rau 890 MPa, Toughness ntawm qis temp). Nws tso cai rau mills hloov pauv hauv chemistry kom ua tiav cov khoom no.
Ntau Lwm Cov Qauv (xws li ASTM A514): Feem ntau chemistry-raws li cov qauv. Lawv qhia txog qhov nqaim, ruaj khov muaj pes tsawg leeg thiab Q&T txheej txheem. Cov khoom siv kho tshuab yog qhov xav tau ntawm qhov tshwj xeeb chemistry thiab txheej txheem.
Qhov sib txawv tseem ceeb no ua rau muaj kev hloov pauv tseem ceeb hauv kev siv tau thiab sib npaug.

Summary : "Gap" Analysis
Lub ntiaj teb toj roob hauv pes nthuav tawm qhov sib txawv tseem ceeb ntawm kev ua haujlwm:
Lub 890 MPa "Club" yog tshwj xeeb:
EN (Tebchaws Europe), ISO (International), thiab GB / T (Tuam Tshoj) muaj cov qauv ntsuas ntawm 890 MPa yield.
ASTM (Tebchaws USA) thiab JIS (Nyiv) cov qauv txheej txheem phaj qib siab tshaj plaws ntawm 690 MPa (100 ksi). Qhov no qhia txog keeb kwm kev nyiam tsim, kev siv vuam, thiab ib txoj hauv kev zoo tshaj plaws rau ultra- siab- lub zog steel hauv kev tsim kho hauv cov cheeb tsam ntawd.
Qhov cuam tshuam rau Ntiaj Teb Cov Haujlwm:
Kev qhia txog S890Q rau ib qhov project hauv Asmeskas lossis Nyij Pooj txhais tau tias koj yuav tsum tau xa cov khoom siv lossis tso siab rau lub tshuab zeb hauv zos uas tsim cov qib "tsis yog-tus qauv" kom tau raws li EN/ISO specifications. Qhov no muaj tus nqi, lub sijhawm ua haujlwm, thiab daim ntawv pov thawj cuam tshuam.
Kev xa tawm sib npaug: Ib tus kws tsim khoom lees txais "ASTM A514 Gr. H" raws li qhov sib npaug ntawm S890Q tab tom ua qhov kev pom zoo loj, lees txais ~ 30% txo qis hauv kev lav yield zog (ntawm 890 txog 690 MPa). Qhov no tsis yog qhov sib npaug tab sis yog ib qho kev rov tsim dua tshiab.
Ntsiab Technical Differentiation Table:
| Yam | TS EN 10025-6 (S890Q) | Hom National Standard Equivalent | Critical Takeaway |
|---|---|---|---|
| Yield zog | 890 MPa (min) | Feem ntau 690 MPa (min) hauv ASTM / JIS | Qhov tseem ceeb tshaj qhov tsis sib xws. |
| Lub npe toughness | L (-40 degree) / L1 (-60 degree) ntshiab system. | Nws txawv (xws li Charpy ntawm -18℃rau A514). | Yuav tsum txheeb xyuas qhov ntsuas kub thiab lub zog tus nqi sib npaug ntawm qhov project qhov kev xav tau kev nyab xeeb tawg. |
| Txoj Cai Tswjfwm | Khoom-Raws li | Feem ntau Chemistry-Based | EN tso cai rau kev tsim khoom yooj yim dua; lwm tus xyuas kom rov tsim dua tshiab ntawm chemistry ruaj. |
| Los ntawm -Thickness (Z) Zoo | Qhia meej meej (piv txwv li, Z15, Z25, Z35). | Nyob rau hauv ASTM, hais nyob rau hauv cais ntxiv yuav tsum tau S1 (Z-kev taw qhia kev ntsuam xyuas). | Yuav tsum tau hu kom meej meej nyob rau hauv qhov kev yuav khoom specification rau ob lub tshuab. |
Cov lus xaus thiab cov lus pom zoo rau cov kws kho mob
Thaum txheeb xyuas cov qhab nia sib xws rau S890Q:
Qhov txawv ntawm "Sib npaug" thiab "Hloov":
Kev sib npaug muaj tseeb: ISO EQ 90 thiab GB / T Q890E / Q890F. Cov no tuaj yeem hloov tau ncaj qha nrog cov ntawv pov thawj tsim nyog.
Feem ntau Misperceived Equivalents: ASTM A514 Gr. H / JIS SHY 685. Cov no tsis sib npaug ntawm lub zog. Lawv sawv cev rau qhov sib txawv, qis qis ntawm qib siab - lub zog steel thiab yuav tsum muaj kev tsim kho dua tshiab.
Rau cov ntawv thov tseem ceeb, Qhia los ntawm Kev Ua Haujlwm, Tsis yog Qib:
Cov kev qhia tshwj xeeb tshaj plaws thoob ntiaj teb yog xav kom ua raws li EN 10025-6: S890QL1 (+ Z35 yog tias xav tau), tsis hais lub teb chaws ntawm kev tsim khoom. Qhov no ua kom koj tau txais cov khoom tshwj xeeb uas xav tau. Mills thoob ntiaj teb tuaj yeem tsim rau tus qauv no yog tias tau teev tseg.
Ib txwm Xav Tau Daim Ntawv Pov Thawj Mill: Daim ntawv pov thawj ntawm kev ua raws li tus qauv teev tseg (EN, ASTM, thiab lwm yam) yog cov ntaub ntawv raug cai uas ua pov thawj cov khoom ua tau raws li qhov xav tau ntawm nws cov tuab. Tsis txhob suav qhov sib npaug raws li qib npe ib leeg.
Hauv qhov tseem ceeb, S890Q tuav lub siab -kev ua tau zoo niche uas tau ua tiav hauv lub koom haum European / ISO tab sis tseem yog ib qho tshwj xeeb, dhau ntawm - cov khoom siv hauv Asmeskas thiab Nyij Pooj. Qhov kev tshuaj ntsuam no qhia txog vim li cas lub ntiaj teb engineering xav tau kev paub cov ntaub ntawv sib sib zog nqus, tsis yog kev tshawb nrhiav lub rooj xwb.
