SA283GrC steel phaj yog tsim rau riveting, bolting thiab vuam cov qauv rau Choj thiab cov tsev. Nws yog cov hlau carbon dav dav nrog cov hlau zoo.
SA283GrC steel phaj xa khoom xwm txheej: kub dov, tswj dov, lub xeev ib txwm xa khoom
Cov khoom siv rau kev tsim lub cub tawg SM400ZL steel phaj:
SM400ZL yog ib daim hlau uas siv rau lub plhaub converter uas yog ua los ntawm cov hlau Nyiv Pooj uas muaj zog tsawg. Cov qauv no qhia txog qhov loj, cov duab, cov kev cai, cov txheej txheem sim, cov cai tshuaj xyuas, cov ntawv ntim khoom, cov cim thiab daim ntawv pov thawj zoo ntawm cov hlau rau lub cub tawg, lub plhaub converter thiab lub cub tawg kub. Nws siv tau rau cov hlau rau lub plhaub cub tawg uas muaj tuab ntawm 8 hli ~ 200 hli. Qhov sib txawv ntawm qhov tuab ntawm SM400ZL steel phaj tsuas yog txwv rau -0.25 hli, thiab thaj chaw kam rau tuab yuav tsum ua raws li GB/T709.
S355NL hlau phaj [8-200 tuab] txiav cov khoom sib xyaw, daim ntawv teev cov khoom siv:
S355NL tus qauv ua haujlwm: EN10025-3: lub npe tag nrho: normalizing/normalizing dov weldable zoo grain hlau qauv phaj. Tus qauv no thiab EN10025-1 ua ke hloov EN 10113-1: 1993 kub-dov weldable zoo grain hlau qauv khoom seem I: Cov xwm txheej dav dav thiab EN 10113-2: 1993 kub-dov weldable zoo grain hlau qauv khoom seem II: normalizing/normalizing dov cov xwm txheej. Thaum qhov kub ntawm qib tsis qis dua - 20 ° C, tus nqi tsawg kawg nkaus ntawm lub zog cuam tshuam tau teev tseg yog qhia hauv N; thaum qhov kub tsis qis dua - 50 ° C, tus nqi tsawg kawg nkaus ntawm lub zog cuam tshuam tau teev tseg yog qhia hauv NL.
2. Lub ntsiab lus sib xws ntawm S355NL steel phaj qib tsab ntawv:
S: cov hlau ua vaj tse, N: lub xeev, peev L: qib ntawm qhov tsawg kawg nkaus teev zog cuam tshuam thaum qhov kub tsis qis dua - 50 ° C
S355ML hlau phaj [8-200 hli tuab] thermomechanical dov
S355ML steel phaj yog xa tuaj rau hauv thermo mechanical dov lub xeev
Cov Kev Cai Siv Tshuaj S355ML
C: ≤ 0.14, Si: ≤ 0.5, Mn: ≤1.6, P: ≤0.025, S: ≤0.02, Nb: ≤0.05, V: ≤0.1, Al: ≤0.02, Ti: ≤0.05, Cr: ≤0.3, Ni: ≤ 0.5, Mo: 5≤0.1, C
S355ML steel phaj yog cov hlau ua los ntawm cov hlau kub dov uas muaj cov noob zoo, uas yog ib feem ntawm cov hlau tsis tshua muaj hlau loj. Nws yog cov khoom tiaj tiaj uas muaj qhov tuab tsis pub tshaj 120 hli thiab cov khoom ntev uas muaj qhov tuab tsis pub tshaj 150 hli. S txhais tau tias cov hlau ua los ntawm cov hlau, 355 txhais tau tias qhov tso zis me me ntawm qhov tuab tsawg dua 16 hli yog 355MPa, thiab M txhais tau tias nws qhov kev xa khoom, uas yog, dov kub. Txoj cai yog tias qhov cuam tshuam ntawm qhov kub tsis pub tsawg dua - 50 degrees yog qhia los ntawm tsab ntawv loj L. S355 yog cov hlau tsis muaj hlau.
Daim ntawv thov ntawm S355ML steel phaj
Ntxiv rau EN10,025-1 hlau, cov phiaj xwm hlau tshwj xeeb uas tau teev tseg hauv tus qauv no kuj tseem siv rau cov khoom thauj khoom ntawm cov qauv welded siv nyob ib puag ncig cov choj, cov kav dej, cov thoob dej cia khoom, cov thoob dej xa khoom, thiab lwm yam thiab nrog qhov kub qis.
