Dachang tiag 304L stainless hlau yeeb nkab muag
Lub koom haum American Iron thiab Steel siv peb tus lej los cim ntau yam qauv
Quasi malleable. Ntawm qhov no:
① Austenitic stainless hlau yog qhia los ntawm cov lej ntawm 200 thiab 300 series,
②Ferritic thiab martensitic stainless hlau yog sawv cev los ntawm 400 series tooj. Piv txwv li, ib co ntawm ntau ntau austenitic stainless hlau
201, 304L, 316 thiab 310,
③ Ferritic stainless hlau yog cim nrog 430 thiab 446, thiab martensitic stainless hlau yog cim nrog 410, 420 thiab 440C
Nco tseg, duplex (austenite ferrite),
④ Stainless hlau, nag lossis daus hardening stainless hlau thiab siab alloy nrog cov ntsiab lus hlau tsawg dua 50% feem ntau yog siv lub npe patent lossis lub npe lag luam.
① Cov cim tshuaj lom neeg thoob ntiaj teb thiab cov cim hauv tebchaws tau siv los sawv cev cov tshuaj muaj pes tsawg leeg, thiab cov ntawv Arabic yog siv los sawv cev cov ntsiab lus:
Piv txwv li: Tuam Tshoj, Russia 12CrNi3A
②Siv cov lej ruaj khov los sawv cev rau steel series lossis cov lej; Piv txwv li, Tebchaws Asmeskas, Nyiv, 300 series, 400 series thiab 200 series.
③ Tus lej xov tooj yog tsim los ntawm cov ntawv Latin thiab kev txiav txim, uas tsuas yog qhia lub hom phiaj.
Daim ntawv thov, Suav Pinyin, qhib hearth steel: P, boiling steel: F, tua steel: B, chav kawm ntawv ib steel: A, T8: te8
GCr15: Pob
◆ cov hlau sib txuas thiab lub caij nplooj ntoos hlav steel, xws li 20CrMnTi 60simn, (C cov ntsiab lus qhia hauv kaum txhiab)
◆ stainless hlau thiab alloy cuab yeej hlau (C cov ntsiab lus yog qhia nyob rau hauv txhiab), xws li 1 txhiab ntawm 1Cr18Ni9 (ie
0.1% C), stainless C ≤ 0.08%, xws li 0Cr18Ni9, ultra-low carbon C ≤ 0.03%, xws li 0cr17ni13mo
Qhov hnyav ib 'meter' ntawm 304L stainless hlau yeeb nkab = sab nraud txoj kab uas hla - phab ntsa thickness x phab ntsa thickness x0.02491
Cov ntsiab lus ntawm 304L stainless hlau yeeb nkab c ≤ 0.03, ni8.00 ~ 12.00, cr18.00 ~ 20.00, Mn < = 2.0, Si < = 1.0, s < = 0.030, P < = 0.035.
304L stainless hlau yeeb nkab 18cr-8ni-qis carbon li Low-C 304 steel, nws cov corrosion kuj zoo ib yam li 304 steel feem ntau, tab sis nws cov qoob loo ciam teb corrosion kuj zoo heev tom qab vuam lossis kev ntxhov siab; Nws kuj tseem tuaj yeem tswj tau zoo corrosion tsis muaj kev kho cua sov, thiab kev pabcuam kub yog - 196 ℃ ~ 800 ℃. Nws yog siv rau sab nraum zoov cov cav tov nyob rau hauv tshuaj, thee thiab roj av industries nrog siab yuav tsum tau rau grain ciam teb corrosion kuj, tshav kub-resistant qhov chaw ntawm lub tsev cov ntaub ntawv thiab qhov chaw uas muaj teeb meem nyob rau hauv kev kho cua sov.
Lub hom phiaj: feem ntau yog siv rau cov dej haus ncaj qha engineering thiab lwm yam kev thauj mus los ntawm cov kua dej nrog cov kev xav tau siab
Cov yam ntxwv tseem ceeb: lub neej ua haujlwm ntev; Tsawg tsis ua hauj lwm tus nqi thiab cov dej to; Lub conveying dej zoo yog zoo, thiab tsis muaj teeb meem khoom yuav raug precipitated rau hauv dej; Sab hauv phab ntsa ntawm cov yeeb nkab yog du thiab tsis tshua muaj dej conveyance kuj; Kev ua haujlwm siab, kev pab lub neej ntev txog 100 xyoo, tsis muaj kev saib xyuas thiab tus nqi qis; Nws tuaj yeem tiv taus cov dej ntws siab ntawm kev yaig ntau dua 30m / S; Tawm yeeb nkab tso thiab zoo nkauj tsos.
Kev siv: mis nyuj thiab zaub mov kev lag luam, kev lag luam tshuaj, kev lag luam nrog tshwj xeeb sab hauv qhov yuav tsum tau muaj.
Txheej txheem nta: Internal weld hlaws leveling kev kho mob, khoom kho kho, sab hauv nto electrolytic polishing.
Kev ua tau zoo: lub puab nto roughness Ra yog ntau tshaj 0.2, phab ntsa dai residue yog me me, yooj yim los ntxuav, tiv thaiv kab mob loj hlob, electrolytic polishing muaj passivation nyhuv, thiab sab hauv phab ntsa muaj kev tiv thaiv zoo.
Kev sim txoj kev: kab rov tav, longitudinal flattening, thim rov qab flattening, hydrostatic test los yog eddy tam sim no flaw detection, mechanical property test, puab nto roughness test.
