M2 vs M35 Kev kub ceev hlau: Koj puas xav tau Cobalt tiag?

Ncua nruab nrabM2 vs M35? Peb rhuav tshem tus nqi tiag tiag ntawm cobalt, liab hardness, thiab vim li cas xaiv qhov zoom35 siab ceev steelyog covqhov kawg zais cia raumachining stainless hlauua tau zoo.

Yog koj arov tsim cov cuab yeej txiav lossis ua haujlwm siab - ntau lawm CNC khw, koj tab tom taug kev nruj nreem. Ntawm ib sab, koj muaj lub siab los ua kom cov nqi cuab yeej nqis. Ntawm qhov tod tes, koj muaj qhov tsim nyog yuav tsum tau ua kom lub tshuab khiav tsis tas nres txhua nees nkaum feeb los pauv tawm ib qho kev xyaum hlawv.

Thaum muab cov khoom siv raw rau kev xyaum, cov kais dej, lossis cov mills kawg, kev sib tham yuav luag ib txwm npau taws rau ib qho kev sib tw classic:M2 vs M35.

Cia peb saib lub hauv paus.M2 siab ceev steelyog tus neeg ua haujlwm tsis sib haum xeeb hauv kev lag luam. Nws nyob txhua qhov chaw. Tab sis tom qab ntawd koj muaj nws cov kwv tij txheeb ze,m35 siab ceev steel, uas yog tus nqi kim heev vim nws muaj kwv yees li 5% Cobalt.

Qhov sib txawv ntawm tus nqi no ua rau txhua tus neeg yuav khoom tus thawj coj mus rau tib lo lus nug uas ntxhov siab:"Peb puas xav tau them nyiaj rau Cobalt tiag tiag?"

Cov lus teb luv luv? Nws tag nrho nyob ntawm qhov koj txiav. Yog tias koj txiav cov hlau me me, muas M35 zoo li yuav Ferrari tsav tsheb hauv thaj chaw tsev kawm. Tab sis yog tias koj yogmachining stainless hlaulos yog titanium, sim txuag nyiaj los ntawm kev siv M2 yuav ua rau koj raug nqi ntau txhiab daus las hauv lub sijhawm poob thiab cov khoom seem.

Nyob rau hauv qhov tob tob no, Promisteel pab neeg hlau metallurgical yuav tshem tawm qhov kev lag luam fluff. Peb yuav saib qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, piav qhia txog cov khawv koob ntawm "Red Hardness," thiab muab cov ntaub ntawv pov thawj rau koj los txiav txim siab thaum twg los npaj cov qauv.m 2 hsthiab thaum twg yuav upgrade rau premiumm35 cobalt hlau.

Ua ntejpeb sib cav txog qhov twg zoo dua, cia peb txhais cov contenders kom meej. High Speed Steel (HSS) tau txais nws lub npe los ntawm nws lub peev xwm txiav hlau ntawm qhov nrawm dua li qub, siab - cov cuab yeej carbon steel.

M2 yog molybdenum-tungsten siab-ceev steel. Yog tias koj taug kev mus rau hauv lub khw muag khoom kho vajtse thiab yuav tus qauv dub - oxide laum me ntsis, yuav muaj feem ua tau los ntawm kev hloov pauv ntawm M2.

Lub Vibe:Txhim khu kev qha, tawv, thiab pheej yig.
Lub Zog:Nws muaj qhov zoo heev - sib npaug sib npaug. Nws muaj cov tawv tawv zoo heev thiab hnav tsis kam, ua rau nws muaj ntau yam rau kev siv dav dav - lub hom phiaj machining.

M35 siv tib lub hauv paus tshuaj raws li M2 thiab ntxiv kwv yees li 5% Cobalt (Co). Qhov ntawd yog tag nrho cov zais cia. Vim qhov no ntxiv, nws yog nquag xa mus rau thoob ntiaj teb lim35 cobalt hlau.

Lub Vibe:High-kev ua tau zoo, kub- tiv taus, thiab hwm.
Lub Strength:Nws tuaj yeem muaj sia nyob ib puag ncig uas yuav ua rau lub ntsej muag ntawm lub cuab yeej M2.

To taub yog vim li cas amere 5% alloy ntxiv tsim xws li ib tug loj tus nqi sib txawv, peb yuav tsum tau saib nyob rau hauv lub microscope.

Ntawm no yog qhov yooj yim chemical breakdown ntawm ob qib:

Element	M2 HSS (%)	M35 Cobalt hlau (%)	Nws ua dab tsi hauv lub cuab yeej
Cov pa roj carbon (C)	0.80 - 0.90	0.88 - 0.95	Muab lub hauv paus hardness. M35 yog me ntsis siab dua.
Chromium (Cr)	3.80 - 4.50	3.80 - 4.50	Sib sib zog nqus hardenability thiab corrosion kuj.
Molybdenum (hli)	4.70 - 5.20	4.70 - 5.20	Muab lub zog ntawm qhov kub thiab txias.
Tungsten (W)	5.90 - 6.70	6.00 - 6.70	Cov ntaub ntawv hnyav heev- tiv taus carbide.
Vanadium (V)	1.70 - 2.10	1.70 - 2.10	Ntxiv rau kev puas tsuaj loj heev.
Cobalt (zeeg)	Tsis muaj / Trace	4.80 - 5.30	Qhov kawg tshav kub daim thaiv.

Saib ze ntawm lub rooj ntawd. Ib cag ntawm cov pob me me hauv Carbon, M35 tsuas yog M2 nrog Cobalt nchuav rau hauv cov yaj.

Yog li, Cobalt tiag tiag ua dab tsi?

Ntawm no yog qhov fascinating ib feem:Cobalt tsis tsim carbide.Tsis zoo li Tungsten lossis Vanadium, uas tsim cov khoom siv tawv me me -zoo li pob zeb hauv cov hlau los tiv thaiv hnav, Cobalt dissolves tag nrho rau hauv cov hlau matrix.

Los ntawm zaum hauv matrix, Cobalt tsa lub melting point ntawm cov hlau sab hauv cov qauv. Nws ua raws li metallurgical scaffolding. Thaum lub cuab yeej tau txais kub tsis txaus ntseeg los ntawm kev sib txhuam, Cobalt tiv thaiv cov qauv ntawm cov hlau los ntawm kev sib tsoo.

Hauv lub ntiaj teb machining, qhov tshwm sim no hu ua"Red Hardness" (los yog Kub Hardness).

Yog koj thawb ibm 2 hsxyaum me ntsis nyuaj, lub ntsis yuav ntaus txog 500 degree, tig xiav, soften, thiab instantly blunt. Ibm35 cobalt hlaulaum ntsis tuaj yeem yog pushed mus rau 600℃los yog txawm 650℃-cia glowing npub liab-thiab tseem tuav ib tug ntse txiav ntug.

Yog muaj nyob raue daim ntawv thov uas zoo kawg nkaus illustratesM2 vs M35debate, yogmachining stainless hlau(tshwj xeeb austenitic qib zoo li 304 thiab 316).

Nug ib tus kws kho mob tshwj xeeb txog kev txiav 304 stainless, thiab lawv yuav zaum quaj. Stainless hlau tsis muaj npe nrov rau qee yam hu ua "ua haujlwm tawv."

Thaum txiav ntug ntawm lub laum tsoo rau saum npoo ntawm stainless hlau phaj, lub siab ua rau thaj tsam ntawm cov hlau tsis muaj zog tam sim ntawd. Yog li, thaum lub laum sim thawb kom tob, nws mam li nco dheev sim txiav cov khoom uas nyuaj dua li nws yog ib feem ntawm ib tug thib ob dhau los.

Qhov no ua rau muaj kev sib txhuam loj heev. Kev sib txhuam loj ua kom muaj cua sov loj.

Koj pib qhov kev pab cuam CNC. M2 laum hits stainless. Lub tshav kub spikes. Vim hais tias M2 tsis muaj qhov siab Red Hardness muab los ntawm Cobalt, qhov txiav ntug ntawm lub laum sai ncav cuag nws qhov kub thiab txias. Lub ntug softens, dov tshaj, thiab lub laum nres txiav. Hloov chaw, nws tsuas yog rub tawm ntawm cov hlau tsis huv, tsim kom muaj cua sov ntau dua kom txog thaum nws snaps lossis melts.

Koj swap lub cuab tam rau ibm35 cobalt hlaume ntsis. Cov cua kub tseem nce siab -koj hloov tsis tau cov cai ntawm physics. Txawm li cas los xij, vim yog 5% Cobalt matrix, cov cuab yeej ntug tsis kam muag. Nws nyob twj ywm nyuaj txaus los tom los ntawm kev ua haujlwm- txheej txheej ntawm cov hlau tsis muaj steel, shearing lub nti kom huv si thiab cia lub coolant ua nws txoj hauj lwm.

Qhov no yog vim li cas, yog tias koj lub khw hauv pem teb tau cuam tshuam nrog Inconel, Titanium, lossis 300-series alloys, M35 tau lees paub thoob ntiaj teb raws li kev mus-rau.high speed steel rau stainless.

Hauv no point, tej zaum koj yuav xav tias:"Yog tias Cobalt zoo heev, vim li cas peb thiaj tsis ua txhua yam ntawm M35, lossis tseem ntxiv 10% Cobalt?"(Spoiler: Qhov ntawd tshwm sim, nws hu ua M42).

Nov yog kev lag luam engineering -tawm:Raws li Liab Hardness nce, Toughness poob.

Vim Cobalt nce qhov kub thiab txias,m35 siab ceev steelyog inherently nkig ntau tshajm2 siab ceev steel.

Yog hais tias koj siv ib tug xyaum tes los yog ib tug me ntsis tsis ruaj tsis khov xovxwm, lub lateral vibrations tau yooj yim snap ib M35 xyaum me ntsis nyob rau hauv ib nrab. M2, ua nruj dua thiab hloov tau me ntsis, yuav muaj sia nyob qhov kev vibration.

Tsis tas li ntawd, M35 nyuaj rau zom. Rau cov tuam txhab tsim khoom, tsim cov mills kawg ntawm M35 yuav siv sij hawm ntau dua thiab hnav cov log sib tsooceev tshaj M2. Qhov no nce tus nqi tsim khoom nyob rau sab saum toj ntawm cov khoom siv raw khoom.

Wb tham about tus ntxhw hauv chav: Tus nqi tag.

Cobalt yog cov khoom lag luam uas tsis muaj zog heev, hnyav hnyav rau kev lag luam hluav taws xob tsheb roj teeb. Vim li no,m35 cobalt hlautuaj yeem yooj yim raug nqi 30% mus rau 50% ntau duam 2 hsrau kg.

Koj ua li cas rau qhov no rau lub chaw yuav khoom? Koj tsis saib tus nqi ntawm cov hlau; koj saib ntawmNqi Ib Ntu.

Cia peb khiav lub khw sai - xam hauv pem teb:

Xav txog tias koj tab tom machining 10,000 flanges tawm ntawm 316 Stainless.

Siv cov cuab yeej M2:Cov cuab yeej pheej yig, tab sis lawv hlawv tawm tom qab 50 qhov chaw. Koj yuav tsum nres lub tshuab CNC 200 zaug los hloov lub cuab yeej. Txhua qhov chaw nres tsheb raug nqi koj 5 feeb ntawm kev tsim khoom ploj. Qhov ntawd yog 1,000 feeb (tshaj 16 teev) ntawm lub sijhawm tshuab tuag, ntxiv rau tus nqi ntawm 200 cov cuab yeej tawg.
Siv cov cuab yeej M35:Cov cuab yeej raug nqi 50% ntau dua. Tab sis lawv kav rau 400 feem. Koj tsuas nres lub tshuab 25 zaug. Koj txuag 14 teev ntawm lub sijhawm tshuab, uas yooj yim them rau cov khoom siv M35 kim dua kaum zaug.

Txawm li cas los xij, yog tias koj tab tom drilling aluminium extrusion lossis me me steel brackets, lub cuab yeej M2 yuav kav ntev mus ib txhis. Hauv qhov xwm txheej ntawd, them nyiajpremium rau M35 tsuas yog pov nyiaj tawm ntawm qhov rais.

Peb xav tau to ntxiv qhov tsis lees paub loj ntawm no. Koj tuaj yeem yuav qhov kim tshaj plaws, ultra- huvm35 cobalt hlaunyob rau hauv lub ntiaj teb no, tab sis yog tias koj cov txheej txheem kho cua sov yog sloppy, lub cuab tam yuav ua phem tshaj ib tug pheej yig daim ntawm carbon hlau.

High Speed Steels xav tau kev kho lub tshuab nqus tsev zoo kawg nkaus.

Austenitizing:M2 feem ntau rhuab mus txog 1190℃txog 1220 degree. M35 yuav tsum muaj qhov kub thiab txias me ntsis (1200℃txog 1240 degree) kom ua tiav cov carbides thiab ua kom cov Cobalt lub peev xwm loj tshaj.
Tempering:Ob qib yuav tsum tau muab ob npaug los yog triple tempering ntawm ib ncig ntawm 540℃mus rau 560℃kom ua tiav cov nyhuv "secondary hardening"-qhov no yog qhov uas cov hlau tau ncav cuag nws qhov siab tshaj plaws hardness ntawm 64-66 HRC.
