Los ntawm kev tswj hwm kev txhim kho thiab kev ua tiav, 304 lub caij nplooj ntoo hlav uas tsis muaj txiaj ntsig, tsis zoo rau cov pa hluav taws xob hauv lub caij nplooj zeeg +300 degree nrog lub sij hawm luv luv ntawm 400 degree.

Los ntawm kev tswj hwm kev txhim kho thiab kev ua tiav, 304 lub caij nplooj ntoo hlav uas tsis muaj txiaj ntsig, tsis zoo rau cov pa hluav taws xob hauv lub caij nplooj zeeg +300 degree nrog lub sij hawm luv luv ntawm 400 degree. Tsis muaj zog sib nqus tom qab cov khoom siv daws teeb meem me ntsis, tej zaum yuav sib nqus me ntsis tom qab ua haujlwm txias. Txhawb cov annealing ci (ba nto) lossis pickling (matte) los txhim kho kev zoo nkauj thiab xeb tsis kam. Rau ntau dua corrosion tsis kam lossis lub zog, customized 316, 301 thiab lwm yam kev daws teeb meem uas muaj.
Chaw Thov:
Automotive Kev Lag Luam: Clutch Springs, Kev Ncua Springs, Lub Rooj Retractors.
A: Nws tuaj yeem siv stably los ntawm -200 degree rau {}} Cov qib, tab sis cov degree tsis kam tuaj yeem raug txo kom dej nag los yog kub.
Q4: Vim li cas yog 304 cov hlau caij nplooj ntoos hlav raug rau xeb hauv chlorinated ib puag ncig?
A: Chlorine ions (piv txwv li dej hiav txwv, cov tshuaj pleev ntsev) yuav rhuav tshem qhov chaw ua yeeb yaj kiab lossis kev ntxhov siab corrosion, thiab nws raug pom zoo kom siv 316 khoom siv.
Q5: Yuav ua li cas xaiv ntawm khaub thuas txav thiab anealed mob?
Txias-twv: Hardness (HB 200-350}), qis elongation (}%), haum rau siab elastic springs. Annealed mob: tsis tshua muaj zog (HB tsawg dua lossis sib luag rau 187), siab dua lossis sib npaug nrog kev tsim lossis vuam.
Q6: Kuv puas yuav tsum tau Anneal tom qab txias kos?
A: If it is necessary to eliminate processing stress or improve plasticity, it is recommended to carry out stress relief annealing at 260-315 degree for 1-2 hours to avoid the risk of brittleness.
Q7: Puas yog nws txhawb kev vuam? Cov kev ceev faj yog dab tsi?
A: VUAM VUAM TAU (Tig Vuam yog qhov xav tau), tab sis cov lus tawm thaum tshav kub yuav tsum tau ua kom tsis txhob muaj kev sib cav sib ceg, thiab cov kev pab cuam
Q8: Dab tsi kev lag luam feem ntau siv 304 lub caij nplooj ntoo hlav feem ntau?
A: Nws ua tau raws li cov zaub mov qib steel steel (piv txwv li GB 4806.9, tab sis peb yuav tsum ua kom cov nplaim paug, thiab peb xaiv electrolytic polishing lossis ba nto.
Q10: Cov kev xaiv muaj dab tsi rau kev kho deg?
Ci annealed (BA): du thiab siab corrosion tsis kam. Pickling Passive: matte nto, tshem tawm cov tawv nqaij oxide. Electrolytic penter: txhim kho corrosion tsis kam thiab txo qhov chaw sab saum toj.
Q11: Yuav ua li cas tiv thaiv hydrogen embrittlement?
A: Dehydogenation ntawm 200 degree rau 4 teev yog xav tau tom qab pickling los yog plating kom tsis txhob ncua qeeb.
Q12: Dab tsi yog cov txheej txheem uas sib haum?
A: qauv diamers ntawm {{{{0}}}}}}}}}.
Q13: Cov qauv hauv ntiaj teb no tau siv li cas?
ASTM A313 (Asmeskas tus qauv) JIS G4314 (Japanese tus qauv Sus 304-} wpb) GB \/ T 4240 (Suav haiv neeg).
Q14: Puas yog ib tus phooj ywg ib puag ncig?
A: Ua raws li Rohs, ncav cuag thiab lwm cov kev ua haujlwm ib puag ncig, tuaj yeem muab cov khoom siv hluav taws xob qhia (piv txwv li melting rauv taws.
Q15: Yuav sim li cas txawm tias qhov zoo yog tsim nyog?
