Peb lub tuam txhab muab cov khoom txias-kuav los tiag stamping seriesSPCCSPCD, SPCE, SPCF, SPFG //dc01 uaDC03, DC04, DC05, DC06, DC07 // ST12, ST13, ST14, ST15, ST16 // BLC, BLD, BUSD, BUFD, BSUFD
DC04 txias-dov phaj thiab sawb yog dav siv, xws li tsheb tsim, khoom siv hluav taws xob, dov Tshuag, aviation, precision instruments, cov kaus poom zaub mov, thiab lwm yam.
DC04 txias-kuav los tiag nyias steel phaj yog cov ntawv luv ntawm cov qauv carbon zoo tib yam steel txias-dov phaj. Nws tseem yog hu ua txias-dov phaj, feem ntau hu ua txias phaj, thiab qee zaus sau yuam kev ua phaj txias. Txias phaj yog ua los ntawm cov pa roj carbon zoo tib yam steel kub-kuav los tiag steel sawb, uas yog ntxiv txias-dov mus rau hauv ib lub phaj steel nrog lub thickness tsawg dua 4 hli. Txij li thaum dov ntawm chav tsev kub tsis tsim cov hlau oxide nplai, lub phaj txias muaj qhov zoo ntawm qhov zoo thiab qhov tseeb qhov tseeb. Ua ke nrog kev kho annealing, nws cov khoom siv kho tshuab thiab cov txheej txheem kev ua tau zoo yog zoo dua li kub-kuav los tiag nyias steel daim hlau. Nyob rau hauv ntau lub teb, tshwj xeeb tshaj yog nyob rau hauv lub teb ntawm cov khoom siv hauv tsev, nws tau maj mam siv los hloov kub-dov nyias steel daim hlau.
DC04 Txoj kev qhia cov qib steel rau kev siv cov qauv hauv Nyij Pooj (JIS tus qauv)
Cim piv txwv: B{{0}}.57501500-GB708-88; steel phaj, tus qauv tooj Q/BQB402, hom SPCC, kho cua sov lub xeev annealed + tiaj (S), nto chaw ua lub xeev yog pitted D, nto zoo yog FB theem trimming (txiav Edge EC, untrimmed ntug EM ) steel phaj, thickness 0.5mm, B-theem qhov tseeb, dav 1000mm, A-theem raug, ntev 2000mm, A-theem qhov tseeb, tsis sib luag qhov tseeb PF.A, ces lub cim yog: steel phaj ECQ / B / (0.51000A2000A- PF.A);
