Steel H12MF: specifications, xyuas

Muaj cov raug kev bearings, tej cuab yeej thiab stamped yog ua li cas siv ntau qib ntawm hlau. Cov lawv ib tug tshwj xeeb qhov chaw yog nyob los ntawm cov hlau H12MF.

Nta ntawm no hom yog tseem menyuam los ntawm ntau lub chaw muag manufacture cov khoom heev dua lwm yam riam. Niaj hnub no, qhov no cov ntaub ntawv uas yog heev nrov nrog manufacturing tuam txhab uas muag, raws li tau zoo raws li ntawm txawv yeej cutlery.

qib hauv chav kawm ntawv

Lub ntsiab hom ntawm mechanical engineering kev lag luam yog suav tias yog H12MF hlau. Khoom yam ntxwv txawv ntawm cov seem carbonaceous cuab tam qhab nia siab nqi qauv ceev. Qhov no hom ntawm steel yog ib tug hauv chav kawm ntawv lub cuab tam stamped. Rau ib ntev lub sij hawm nws tau tsuas yog siv nyob rau hauv qhuav ntawm hnub rau dabtsi yog khoov thiab molding khoom. Txij li thaum H12MF forged hlau yog ib co resistant mus rau sab nraud lub cev tej yam, nws yog siv nyob rau hauv heavy kev lag luam thiab engineering kev lag luam.

Qhov no yog ib tug zoo steel ntaub ntawv los ntawm uas yog ua kev yos hav zoov cov riam. Raws li evidenced los ntawm heev heev xyuas ntawm tau txais kev pab, xws tej khoom uas siab zog thiab ntev tupyatsya, uas yog ib qho tseem ceeb rau cov neeg yos hav. Zoo ntaub ntawv sau cia los ntawm manufacturers siv nyob rau hauv ntau lawm H12MF hlau.

zog

Qhov zoo ntawm no steel qib yog:

• siab zog;
• thaum tshav kub kub kuj;
• hardenability;
• quenchability;
• durability;
• processability.

Cov yav tas cuab yeej yog soj ntsuam masters H12MF machining hlau. Tus yam ntxwv ntawm lub hom cia nws ua los ntawm txoj kev txiav cov txheej txheem, siab thiab kev sib tsoo.

khoom

Mark H12MF siv nyob rau hauv qhov siv thiab ua:

• profiling chais muaj ib tug complex zoo lawm;
• dyroproshivnyh complex matrices, los ntawm txoj kev uas daim ntawv hlau yog tsim;
• txheem iav;
• dov lub dice;
• portages;
• matrices;
• punches.

Yuav ua li cas muab cov ceev?

High nqi, uas muaj lub steel H12MF, yam ntxwv ntawm lub cim no tiav los ntawm teb rub cov khau. Thaum lub sij hawm txoj kev coj mus rau cov txheej txheem round steel tuav muab tso nyob rau hauv ib tug tshwj xeeb kub. Nws muaj nws yog rhuab mus rau ib tug tej yam kub. Tom qab ntawd caskets H12MF mechanically tiav siv ib tug rauj. Raws li ib tug tshwm sim, yuav tsum tau ib tug bar ntawm hlau nrog ib tug heev kev kub ceev. Ces nws yog dua muab tso rau hauv lub cub tawg thiab raug los ua cua sov kev kho mob. Thaum lub sawb yog txaus sov li, txiav nws mus rau hauv me me daim.

Tom qab, los ntawm cov zauv lawv txuas mus rau lub Desired npoo zoo. Nyob rau hauv no, cov riam no yog ua los ntawm steel H12MF. Xyuas cov tswv ntawm xws li tuaj yog feem ntau zoo cim: cov qauv ntawm cov hlau billet thaum lub sij hawm ua rauj ua heev tuab, thiab qhov no, nyob rau hauv lem, muab siab kuj mus tuaj blunting.

Yog vim li cas alloying hais?

Nyob rau hauv nws cov thawj daim ntawv no, tej li ib txwm steel yog ib tug hlau muaj li ntawm hlau thiab carbon. Nyob ntawm seb cov paub tab yuav tsum tau ua los ntawm cov khoom, nqa tawm ib yam tshuaj hloov ntawm lub alloy, thiab qhov no, nyob rau hauv lem, pab txoj kev thiab adapts steel H12MF. Cov yam ntxwv (kev paub meej tias cov lus qhia) zoo cov ntaub ntawv uas yog nyob rau hauv lub nram qab no:

• siab zog;
• zoo xeb kuj;
• lag luam durability;
• siab tej peev xwm.

Cov ntaub ntawv zoo H12MF acquires qhov sib ntxiv ntawm alloying ntsiab nyob rau hauv nws. Tus txheej txheem yog nqa tawm nyob rau hauv ib tug tej yam kub tsoom fwv kom tau raws li qhov yuav tsum tau npaum li cas ntawm hardening.

qauv

Riam H12MF steel muaj cov nram qab no tshuaj hais:

• Chrome. Nws yog tswvcuab los txhim kho tej khoom thiab hnav kuj ntawm lub steels.
• Wolfram. Qhov no tshuaj caij tej lub hardenability.
• Vanadium. Nws yog tsim nyog los qualitatively faib nyob rau hauv tus qauv ntawm lub steel hais tshaj theem. Vim muaj cov vanadium nyob rau hauv muaj pes tsawg leeg tshuam txo rhiab heev rau overheating. Thaum ib tug dhau heev lawm ntau npaum li cas ntawm tej yam khoom uas (5%) txo yas thaj chaw uas yuav tsum tau muaj H12MF hlau. Cov yam ntxwv (kev steel khoom uas tuav tag nrho paub meej tias nws) ntawm cov khoom nyob ntawm seb tus nqi ntawm cov vanadium. Tus me dua cov xub ntiag ntawm lub tshuaj lub caij, lub siab dua indices ntawm lub dag lub zog thiab ductility ntawm hlau.
• Molybdenum. Qhov no tshuaj caij tej lub hardenability thiab toughness ntawm hlau. Nyob rau tib lub sij hawm lub xub ntiag ntawm loj nyiaj ntawm molybdenum hlau muaj peev xwm ntawm tej tus kuj mus rau tsim ntawm burrs. Desirably, cov ntsiab lus ntawm cov tshuaj yeeb dej caw nyob rau hauv H12MF tsis pub tshaj 1.7%.
• Manganese. Qhov no tshuaj caij yog tsim nyog los txo kev nkhaus thaum lub sij hawm hardening khoom.
• Silicon. Siv los txhim kho lub ua hauj tempering thaum lub sij hawm thaum tshav kub kub kev kho mob.

Siv thiab ua cov nias steel hlau yog nqa tawm kev noj mus rau hauv tus account uas yuav tsum tau ntawm cov qhua.

H12MF: tus nqi abbreviations

Decrypt steels nyuaj. Ua ntej ntawm tag nrho cov koj yuav tsum paub uas cov tsiaj ntawv yog siv thaum xa mus rau tshuaj lom neeg hais. Yuav kom qhia tau tias cov chromium thov tsab ntawv X, Ni - H, cobalt - K, vanadium - F, molybdenum - M, titanium - C, tooj liab - .. D, etc. Yog li ntawd, lub steel H12MF nyob rau hauv nws muaj pes tsawg leeg muaj chromium, molybdenum thiab vanadium. Reference tus nab npawj denoted lub ntsiab ntsiab lus ntawm cov alloying caij. Lawv yog chromium. 12% ntawm cov tshuaj lub caij muaj ib tug steel H12MF.

yam ntxwv ntawm

Riam, tsim los ntawm cov khoom ntawm cov hom no muaj tej yeeb yam uas muab cov kev steel Cheebtsam muaj nyob rau ntawd. Txij li thaum H12MF yog cov hlau, cov khoom hauv therefrom xam qhovkev siab coj kuj. Qhov no txhais tau tias ib tug hniav ntawm siab carbon index yuav siv tau rau ib tug ntev lub sij hawm tsis muaj sharpening. Cov pa roj carbon 16% txhais uas yuav muaj steel H12MF yam ntxwv. Tuaj ua los ntawm ib tug chromium steel (12%), yuav luag tsis muaj xeb. Nyob rau hauv cov kev tshwm sim hais tias tus steel muaj 14% chromium, nws yuav kiag li stainless. Lub xub ntiag ntawm tshuaj ntsiab muab cov ntaub ntawv H12MF tuaj ntawm lub dag lub zog thiab durability. Muab puas kuj yog tau vim ntxiv dopant. Rau lub hom phiaj no, thaum lub sij hawm calcination H12MF ntxiv molybdenum. Raws li ib tug tshwm sim, lub steel yog annealed uniformly. Riam ua los ntawm nws, yog ib yam khoom nrog ib tug uniform hliav. Raws li evidenced los ntawm heev heev xyuas ntawm cov tswv ntawm cov hniav, nyob rau hauv cov qauv ntawm cov tuaj yog tsis muaj zog me ntsis.

Riam xeem ntawm H12MF

Test ntawm steel mus yos hav zoov riam yog qhov khoom ntawm raws li nram no:

• Riam ua rifling rau cov hlua 200 mm. Nyob rau hauv lub tswv yim ntawm cov tswv, cov hniav yuav yooj yim ua rau tsawg kawg peb puas rifling. Tsuas ces nws yuav tau pom tias tus hniav yog blunt.
• Rau grooves kuj siv ntoo qhib tuav. Nyob rau qhov no cov ntaub ntawv uas riam yuav ua kom tsis muaj ntau tshaj li ib puas rifling.
• Nws txiav cov ntawv xov xwm. Lub essence ntawm qhov kev xeem no zoo yog mus ntsuam xyuas lub sharpness ntawm lub riam. Rau lub hom phiaj no, cov hniav maj mam muab nws txo qis ib cov ntawv xov xwm page. Feem ntau, ib daim ntawv yog yooj yim txiav mus rau hauv ob daim heev dua lwm yam nyob rau hauv tus ntawm nws tus kheej yuag.

Txawm tias tag nrho cov zoo ntawm steel H12MF, ntau cov tswv ntawm cov tuaj yog pom zoo kom raws li ob txoj cai:

• Txij li thaum lub yos hav zoov cov riam yog tsis missile riam phom, muab pov tuaj ntshaw kom ntoo los yog lwm qhov chaw.
• Tsis txhob mus saib cov tuaj dabtsi yog khoov thiab tsis mus rau kauj ruam rau lawv.

Cov uas muaj muas tau ib yam ntawm cov riam, tej zoov kom tsis nkim koj txhais tes rau polishing cov hniav. Raws li rau ntau cov kev pab, H12MF heev heev polished. Li ntawd, cov riam ua los ntawm steel ntawm lub hom yuav yeej tsis ci tuaj.

Cov yam ntxwv xim ntawm nws rab ntaj - matt. Nyob rau hauv no hais txog, steel riam H12MF feem ntau tsis meej pem nrog damask.

xaus

Steel H12MF hom menyuam los ntawm cov manufacturers ntawm cov ntau yam cuab yeej thiab cutlery khoom, raws li zoo raws li cov kev pab.

Cov neeg uas tau txiav steel khoom H12MF, hais txog riam heev dua lwm yam zoo. Siv cov tuaj yuav ua tau yooj yim qhib tin poom, mus nti ntoo ceg thiab tsuav cov pob txha rho tawm tsiaj nyaum. Nyob rau hauv teb tej yam kev mob, cov kev ua yog cov feem ntau.

Tsis pub tsawg tshaj li zoo xyuas los tshuav tau txais kev pab bearings, stamped thiab txiav cov cuab yeej ua los ntawm steel H12MF. Raws li qhov kev paub ntawm H12MF khoom tau yooj yim daws nrog tej neeg ua hauj lwm.
