Steel 95X18: specifications, xyuas, thaum tshav kub kub kev kho mob thiab cov raug kev riam

Muaj ntau hom kev steel, txhua tus uas nws muaj nws pluses thiab minuses. Nws yog yog li ntawd tsim nyog paub dab tsi hlau mus yuav no los yog tias cov khoom no yog tias nws tau txais kev pab raws li ntev li sai tau.

steel universal

Rau cov yam ntxwv ntawm cov hlau yam khoom raws li nws cov geometry, tiam sis feem ntau ib tug hlau qauv, uas nyob rau hauv lem yog nyob ntawm nws muaj pes tsawg leeg thiab qhov tsim nyog thermal, tshuaj thiab txhua yam kev kho mob. Nws yog ib lub ua ke ntawm cov kev qhia txog xws li ib tug lossis loj tus naj npawb ntawm qib ntawm steel thiab tiav lawm cov khoom. Txij li thaum muaj ntau tseem ceeb nyob rau hauv cov yam ntxwv ntawm cov hlau cov khoom (tej zaum tsuas tsim nyog lub dag lub zog thiab ductility yog tej zaum xwb), cov hlau yog chiv xaiv los ntawm lawv cov tshuaj nyob tus yeees, thiab tau txais zaum kawg zog siv ntxiv ua.

Lub ua ke ntawm qualities

ua hom raug xaiv los ua zoo li sai tau rau txhua qhov, thiab yog hais tias tsim nyog, ib tug me me ib feem ntawm nws. Lawv nyob ntawm seb, raws li ib tug txoj cai, nyob rau hauv uas siv yuav siv sij hawm qhov chaw nyob rau hauv lub cell thiab dab tsi load nws pom tau tias (kev sib txhuam, dynamic, tensile, compression). Raws li, lub teeb thiab cov hom phiaj: mus cuag cov hardness, ductility, los yog ib tug ua ke ntawm cov qualities. Tau txais lub tib hardness, muaj zog, ductility can rau steels nrog sib txawv tshuaj nyob tus yeees, tab sis tej zaum lawv yuav muab ib tug unsatisfactory tshwm sim los ntawm lwm yam kev. Tab sis ib tug thiab tib hlau yuav raug siv los kos qhov chaw sib txawv ntawm cov hom phiaj. Yog li, rau pirmeru steel 95X18 yuav ua tau lub hauv paus rau qhov siv thiab ua cov ntau qhov chaw, tab sis, nrog uas zoo sib xws yuav tsum rau tensile zog thiab hardness. Cov khoom thiab cov ntsiab lus tej zaum yuav muaj ntau haiv neeg: lub tes tsho axis, bearings, tab sis qhov zoo tshaj plaws steel exhibits nws tus yam ntxwv nyob rau hauv cov mus yos hav zoov cov riam.

Nta thiab muaj peev xwm

95X18 - ib qho ntawm qhov zoo tshaj plaws thiab cov tswv yim steels siv rau qhov siv thiab ua tuaj nrog tshwj xeeb muaj zog ua tau zoo. Feem ntau, qhov no yog qhov khoom rau zoov. Cov neeg preferring cov riam ntawm no hom, kom lawv xaiv tsis los ntawm lub caij. Txawm tias yuav tsis mus nrhiav tus intricacies ntawm metallurgy, pab kom zoo dua kawm los ntawm tus steel riam 95X18 xyuas ntawm lwm cov neeg, uas koj muaj peev xwm to taub heev. Namely, qhov no yog qhov zoo tshaj plaws cov ntaub ntawv uas rau no hom ntawm cov khoom.

Sab lub tshuaj nyob tus yeees thiab thaj chaw ntawm no hlau yog tsis yog li ntawd ntev dhau los. Tab sis nws loj hlob tej chaw hais tias ntau npaum li cas txog cov muaj cov ntawm no cov ntaub ntawv uas. Ua hauj lwm nrog cov hlau mas kev tuam txhab uas muag, raws li nws yog heev capricious, nws xam qhovkev tsis xws luag xws li burnout los yog tsis muaj lub caij so. Ua li no, peb yuav tsum tau cov neeg uas muaj ib tug paub zoo txog ntawm rooj plaub thiab stalevarnogo niaj hnub precision khoom, uas muaj peev xwm them taus xwb lub tuam txhab tso koom nyob rau hauv zus tau tej cov riam thiab lwm yam hlau cov khoom.

forging kev kho mob

Lub xub ntiag ntawm chromium nyob rau hauv nws cov tshuaj nyob tus yeees pushes high-zog steel nyob rau hauv ib tug xov tooj ntawm corrosion resistant los yog corrosion-ntawv pov thawj. Nyob rau hauv tas li ntawd, lub steel yog rau 95X18 forging. Rau ib yam ntawm cov hlau qauv ntawm txoj kev ua no yog ib tug "kev kho mob" ntawm ntau cov kab mob, feem ntau ntawm uas microcracks filling pores teeb meem hais hydrogen, oxygen, thiab, ntawm chav kawm, txoj haujlwm (qhov chaw tsis nyob los ntawm cov atom, uas tas ib tug kab noj hniav). Sib nrug los ntawm lub "tus kab mob", forging pab tau tshem ntawm cov tshuaj thiab dendritic segregation, nruj nreem ntau "equip" tag nrho cov molecules. Nrog rau qhov no structuring nyuaj hlau grain ca tshwm sim. Qhov no tso cai rau koj los mus nce lub plasticity tsis compromising zog. Tom qab ntawd 95X18 steel muaj cov yam ntxwv muaj peev xwm ntawm tiv siab loads txawm nyob rau hauv dabtsi yog khoov.

Tus duab ntawm lub riam yog tsis muaj tsis tseem ceeb

Tsim nta txiav khoom Nkij los txuam rau thiab txhim khu lub functionality. Lawv raug faib lub load thiab siv ntawm tus hniav ib qho yooj yim thiab yooj yim. Nyob rau hauv lub chaw ua khoom ntawm hniav tseem ceeb heev yog txuas mus rau hauv daim ntawv, loj, me, txoj kev sharpening lub ntug thiab mus rau ib tug txoj kev fastening tus kov. Txhua yam ntawm cov khoom no muaj ib tug xav paub ntau dua haum. Lawv kom yooj yim thiab txhim khu lub artistic tus nqi ntawm cov khoom. Yog ib tug tib dependence rau lub thickness ntawm cov hniav thiab tej zoo. Lub thinner cov hniav, lub zoo dua lawv ua me ua hauj lwm.

ntau lawm technology

Steel 95X18, riam uas yog tau nrog ib tug heev muaj zog thiab check ntug, yuav tsum tau mus los ntawm ob peb theem ntawm kev. Cov ua hauj lwm pib los ntawm muab castings ntawm loj me me uas yog annealed ua ntej forging (lub workpiece yog rhuab mus rau 885-920 degrees Celsius thiab khaws cia rau 1-2 xuab moos). Nws yog ib qho tseem ceeb heev kom tsis txhob hlawv los ntawm hlau. Yog hais tias qhov no tshwm sim, lub workpiece yog tsis raug mus ntxiv ua. Tsuas yog tom qab xws li raug tus kab mob tau cov txiv ntseej npaj yuav forged. Vim hais tias nws yog tsim ntawm yam phaj loj. Yog ntxiv nyiaj rau machining (sib tsoo, polishing). Tom qab tag lub forging preform yog sai txias nyob rau hauv lub cav roj. Qhov no yog hu ua tempering. Nyob rau hauv cov kauj ruam no, lub steel muaj ib tug heev brittleness, thiab yog hais tias nws tsis yog muab tshem tawm, lub hlau nrog ib tug me me ceeb yuav crumble li iav. Tej zaum qee zaum pom muaj ua hauj lwm novice tswv, tiam sis feem ntau steel 95X18 xyuas tau txais los ntawm lub zoo neeg. Cov nyiaj so koobtsheej sij yog ib tug rhuab preform, tab sis mus rau sab kub - tag nrho mus txog 200-300 degrees Celsius.

ntug kev kawm ntawv

Riam ntug tau txais nws zoo nyob rau hauv ob dhau mus. Tus thawj mus kom ze tso cai rau koj kom tau xwb thawj zaug loj, lub thib ob - ntau yog. Tam sim ntawd tom qab thawj zaug zaum kawg tuav nyiaj so koobtsheej machining. Cov hniav nyob rau hauv cov tshuab grinds kom haum rau koj xav tau kev pab. Steel 95X18, Thaum tshav kub kub kev kho mob uas extends nyob rau hauv plaub theem ua zaum kawg zog tom qab lub thib ob tempering, uas tag nrho cov voltages raug muab tshem tawm - thiab cov hlau yuav nyiaj pab ntau tshaj ductility. Rau lub hom phiaj no lub tiav lawm hniav yog khaws cia ntawm 150 degrees rau 1-2 teev. Cua txias yuav siv sij hawm qhov chaw nyob rau hauv cov huab cua. Yuav kom kho cov hniav peculiar qauv etching tej zaum yuav tsum tau ua nrog acid.

Tu rau riam

Txawm tias nws hardness thiab durability, steel yog raug mus qeeb degradation. Ntawm cov hoob kawm, tus txheej txheem no yuav siv sij hawm ntau tshaj ib tug kaum os los yog txawm ib puas xyoo, tab sis nws muaj peev xwm yuav tsis tshua los ntawm accelerating kev kho mob.

95X18 steel, muaj nyob rau hauv nws muaj pes tsawg leeg ib tug nce cov ntsiab lus ntawm chromium, yus muaj los ntawm nws cov xeb kuj, uas tsub kom qhov kev pab lub neej. Cov khoom ua therefrom kuj muaj no feature, tab sis raws li lub steel nws tus kheej, thiab tsim nta ntawm tus hniav nws tus kheej yuav tsum tau ceev faj kev kho mob.

• Neeg kho tshuab loads. Koj siv tsis tau cov riam rau lwm yam. Load, xam nyob rau ua thiab cov hniav ntug yuav txov ntau cov ntaub ntawv, xws li muaj zog heev (ntoo, hlau, thiab hais txog. D.), Tab sis nws yog tus thawj rau raug kev txom nyem thiab lub curvature ntawm tus hniav hliav.
• Ya, ya raws, acidic ib puag ncig. Txawm tias muaj tseeb hais tias cov hlau 95X18 corrosion-resistant, heev kev sib cuag nrog ib tug tov nrog ib tug high school cov ntsiab lus ntawm cov ntsev adversely muaj feem xyuam rau qhov chaw. Nyob rau hauv tib txoj kev, raws li tau zoo raws li ib tug ntev nyob rau hauv ib lub noo qhov chaw.

Lub tshuab uas siv los ntawm riam, raws li zoo li lwm yam steel khoom, subordinated rau lub xeev cov qauv, cov txheej txheem maps thiab cov lus qhia. Qhov no hom ntawm steel no mas muaj nuj nqis tsis tsuas yog nyob rau hauv ib ncig ntawm Russia. Nws yog li yooj yim los sib tw nrog txawv teb chaws hom, thiab ntau yam ntawm lawv yog superior rau qhov yooj yim tsis. Tab sis, dua li no, cov khoom ntawm txhua tus tswv nws muaj nws sib txawv. Qhov no qhia tias ua hauj lwm nrog hlau, tsis tsuas txheej txheem, feem ntau ib tug txoj hauj lwm.
