FAQ
CK45 steel sib npaug li cas?
CK45 yog German DIN tsim rau nruab nrab - carbon steel uas nws qib European yog C45E (cov ntaub ntawv naj npawb 1.1191). Nws qhov sib npaug ncaj qha yog AISI / SAE 1045 (USA), JIS S45C (Nyiv), GB 45 # (Tuam Tshoj) thiab BS 080M46. Hauv daim ntawv raj nws tau muab rau EN 10305-1 li C45E, rau ASTM A519 raws li Qib 1045, thiab rau JIS G3445 li STKM13C.
Puas yog CK45 zoo ib yam li C45E?
Yog lawm. CK45 thiab C45E yog tib cov hlau raws li cov khoom siv 1.1191. CK45 yog lub npe laus DIN 17200; C45E yog lub npe EN tam sim no thiab daim ntawv siv nyob rau hauv EN 10305-1 rau precision raj. Siv C45E / 1.1191 ntawm kev txiav txim tshiab kom daim ntawv pov thawj sib tw rau tus qauv tam sim no, thiab hais CK45 tsuas yog thaum sib piv cov duab qub.
Vim li cas CK45 qhia ob qhov txiaj ntsig tawm los?
Vim tias qhov kev tawm los yog teeb tsa los ntawm kev xa khoom, tsis yog qib. Lub npe CK45 kho tsuas yog chemistry; lub zeb ces muab nws txias drawn (+C), maj mam stress-relieved (+LC), stress-relieved (+SR), annealed (+A) or normalized (+N). Lub raj zoo li qub muab qhov tsawg kawg nkaus ntawm 380 MPa; kev ntxhov siab-relieved raj muab 420 MPa - qhov sib txawv 40 MPa los ntawm kev ua haujlwm ib leeg. Tsim kom muaj nuj nqis ntawm qhov xwm txheej koj tau xaj.
CK45 puas tuaj yeem hardened?
Yog lawm. Tsis zoo li cov qib qis - carbon E235 / E355 precision, CK45 yog quenching - thiab - tempering steel. Quenched (820–855 degree) thiab tempered (550–660 degree) nws ncav cuag 620–850 MPa tensile nrog zoo toughness, thiab saum npoo yuav induction- hardened rau 54–58 HRC. Nws dhau los ntawm - hardens txog li 60 mm seem; Cov ntu loj dua harden feem ntau ntawm qhov chaw. Carburizing tsis tas yuav tsum tau - uas yog qis- cov txheej txheem carbon hlau.
Puas yog CK45 weldable yam tsis muaj preheat?
Tsis yog, tsis muaj kev nyab xeeb. Ntawm 0.42–0.50% carbon nws cov pa sib npaug (CEIIW) sau txog 0.60–0.65%, yog li qhov kev pheej hmoo tawg yog qhov siab tshaj qhov qis dua -carbon E355. Preheat rau kwv yees li 150-250℃nyob ntawm phab ntsa tuab thiab tuav, siv qis -hydrogen electrodes, thiab siv tom qab-weld kev ntxhov siab. Yog tias koj lub rooj sib dhos yog welded thiab tsis muaj cua sov- kho tom qab ntawd, lub raj E355 lossis E420 yuav yog qhov pheej yig dua, qis dua - kev xaiv pheej hmoo.
Qhov kev xa khoom twg kuv yuav tsum xaiv rau CK45 precision raj?
Xaiv los ntawm qhov yuav tsum tau ua. Xaiv +N (normalized, yield 380 MPa) rau cov khoom siv dav dav thiab zoo sib xws ntawm tus nqi qis tshaj. Xaiv +SR (kev ntxhov siab-txo qis, tawm los 420 MPa) thaum koj xav tau 40 MPa ntxiv ntawm cov khoom tawm los yog cov seem seem nruj dua- tswj kev ntxhov siab rau honing lossis lub teeb txias txias. Xaiv +A (annealed) rau hnyav machining, + C / + LC (txias kos nyuaj) tsuas yog thaum lub raj tiav los ntawm kev sib tsoo thiab tsis txhob khoov lossis welded.
Qhov luaj li cas ntawm EN 10305-1 C45E npog?
TS EN 10305-1 npog cov hlab txias seamless ntawm 4 hli mus rau 380 hli sab nraud txoj kab uas hla thiab 0.5 hli mus rau 25 hli phab ntsa thickness. Saum toj no 380 hli OD tib lub C45E steel yog muab raws li EN 10297-1 raws li ib tug neeg kho tshuab (kub tiav los yog txias tiav) raj, qhov twg cov yield yog quoted nyob rau hauv kub-tiav lub hauv paus thiab daim ntawv pov thawj hais txog ib tug txawv tus qauv. Paub meej txog txoj kev ua ntej qhia txog lub tog raj kheej loj.
Puas yog CK45 haum rau qis-kev pabcuam kub?
Tsis yog. CK45 yog ib qho nruab nrab- carbon structural steel uas tsis muaj kev cuam tshuam rau qhov hnyav ntawm qhov kub thiab txias, yog li nws yuav tsum tsis txhob hloov pauv rau cov pa roj carbon tsawg lossis nplua - cov hlau nplej (piv txwv li A333 Qib 6 lossis EN 10216-4 P265NL). Siv nws rau chav -kub tshuab, hydraulic thiab pneumatic thooj voos kheej kheej, thiab kev tsim vaj tsev dav dav uas cuam tshuam ntawm qhov ntsuas kub qis tsis yog qhov tsim qauv.
