Copper Cu: 0.20 lossis tsawg dua
SA283GrC steel phaj yog tsim rau riveting, bolting thiab vuam qauv rau choj thiab vaj tse.Nws yog lub hom phiaj dav dav carbon structural steel nrog cov qauv hlau zoo.
SA283GrC steel phaj tus me nyuam raws li txoj cai: kub dov, tswj dov, ib txwm lub xeev ntawm tus me nyuam
Khoom siv rau lub tsev tawg rauv SM400ZL steel phaj:
SM400ZL yog ib tug Japanese txheem low-alloy high-strength steel phaj rau converter plhaub.Cov qauv no qhia txog qhov loj, cov duab, cov kev xav tau, cov qauv kev sim, kev soj ntsuam cov cai, ntim, cov cim thiab daim ntawv pov thawj zoo ntawm cov hlau phaj rau lub tshuab hluav taws xob tawg, hloov pauv thiab kub kub blast furnace shells.Nws muaj feem xyuam rau cov phaj hlau rau lub tshuab hluav taws xob nrog lub thickness ntawm 8mm ~ 200mm.Qhov tsis zoo thickness sib txawv ntawm SM400ZL steel phaj yog txwv rau -0.25mm, thiab lub thickness kam rau ua raws li GB / T709.
S355NL steel phaj [8-200 tuab] txiav muaj pes tsawg leeg, cov npe khoom:
S355NL tus qauv kev tswj hwm: EN10025-3: tag nrho lub npe: normalizing/normalizing dov weldable fine grain structural steel phaj.Cov qauv no thiab EN10025-1 ua ke hloov EN 10113-1: 1993 kub dov weldable zoo grain steel khoom Tshooj I: Cov xwm txheej dav dav thiab EN 10113-2: 1993 kub dov weldable zoo grain cov khoom steel Tshooj II: normalizing / normalizing dov steel tej yam kev mob.Thaum qhov ntsuas kub ntawm qib tsis qis dua - 20 ° C, qhov tsawg kawg nkaus tus nqi ntawm qhov kev cuam tshuam lub zog tau qhia hauv N;Thaum qhov kub tsis qis dua - 50 ° C, qhov tsawg kawg nkaus tus nqi ntawm qhov kev cuam tshuam lub zog tau qhia hauv NL.
2. Lub ntsiab lus ntawm S355NL steel phaj qib ntawv:
S: structural steel, N: xeev, peev L: theem ntawm yam tsawg kawg nkaus kev cuam tshuam lub zog thaum kub tsis qis tshaj -50 ° C
S355ML steel phaj [8-200mm tuab] thermomechanical dov
S355ML steel phaj yog xa nyob rau hauv thermo mechanical dov lub xeev
S355ML Chemical Composition Requirements
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: ≤0.1, Cu: ≤0.55, N: ≤0.015.
S355ML steel phaj yog kub-kuav los tiag weldable zoo grain structural steel, teej tug mus rau ib tug series ntawm tsawg-alloy high-lub zog steel daim hlau.Nws yog cov khoom lag luam tiaj tus nrog lub thickness tsis ntau tshaj 120mm thiab cov khoom ntev nrog lub thickness tsis tshaj 150mm.S txhais tau hais tias cov qauv hlau, 355 qhia tias tus nqi me me ntawm qhov cuam tshuam thickness tsawg dua 16 hli yog 355MPa, thiab M sawv cev rau nws tus me nyuam, uas yog, kub dov.Txoj cai yog tias qhov cuam tshuam ntawm qhov kub tsis tsawg dua - 50 degrees yog qhia los ntawm tsab ntawv loj L. S355 yog non alloy structural steel.
Daim ntawv thov S355ML steel phaj
Ntxiv rau EN10,025-1 steel, cov phiaj xwm hlau tshwj xeeb tau teev tseg hauv tus qauv no kuj tseem siv rau cov khoom thauj khoom ntawm cov khoom siv welded siv nyob ib ncig ntawm cov choj, cov kav dej, cov tso tsheb hlau luam, cov kav dej, thiab lwm yam.
