Hmoov tsis zoo, tshawb txog Is Taws Nem loj hauv kev tshawb nrhiav cov lus yooj yim thiab nkag siab txog cov ntsiab lus ntawm cov qauv hlau thiab cov hlau hauv cov ntsiab lus, qhov zoo tshaj plaws, koj yuav pom ob peb nqe lus uas tsis muaj kev nkag siab ntau. Hauv lwm qhov xwm txheej, cov ntaub ntawv tau muab rau hauv daim ntawv yooj yim clippings los ntawm cov ntaub ntawv tswj hwm, qhov twg tag nrho cov ntaub ntawv yuav raug muab rau hauv daim ntawv ntawm kev tsis paub txog kev tshawb fawb thiab kev siv cov ntawv luv luv thiab cov npe.

Lub xeev no tsis haum rau peb, yog li hauv tsab xov xwm niaj hnub no, peb tsuas yog tau paub txog cov yam ntxwv tseem ceeb ntawm 40ХН steel ntau npaum li qhov ua tau, thiab tseem tham txog nws cov peev txheej thiab tshuaj muaj pes tsawg leeg.

Siv

Cia pib peb qhov kev mus ncig nrog qhov yooj yim tshaj plaws, uas yog, nrog cov lus teb rau lo lus nug tseem ceeb. Qhov no steel siv nyob qhov twg los yog, paraphrase me ntsis, rau kev lag luam twgCov yam ntxwv ntawm steel 40ХН yuav xav tau tshaj plaws?

Yog tias peb xa mus rau cov ntaub ntawv, uas yog rau GOST 4543-71, nws yuav pom tseeb rau peb tias 40ХН steel yog cov qauv, alloyed, chromium-nickel. Lub npe no ua kom pom tseeb tias qib ntawm cov hlau no feem ntau yog siv rau kev tsim khoom. Feem ntau, kev siv 40XH hlau yog ze ze rau kev tsim cov khoom rau ntau yam txheej txheem.

Piv txwv li, axles thiab shafts ntawm lub cav, lub zog, cov menyuam, txuas pas nrig, levers thiab ntau ntxiv yog feem ntau ua los ntawm 40XH. Tag nrho cov saum toj no yog cov loads siab thaum lawv ua haujlwm tag nrho, los ntawm qhov peb tuaj yeem txiav txim siab tias cov yam ntxwv thiab cov khoom siv ntawm 40XH steel tsis yog phem heev.

Txawm li cas los xij, koj yuav tsum tsis txhob xav tias cov hlau ntawm qib no twb tau tsim nyob rau hauv daim ntawv ntawm cov khoom tiav lawm. Zoo li lwm yam hlau, 40ХН tau muab tso rau hauv kev lag luam hauv daim ntawv strips, tuav, hexagons, squares uas paub txog txhua tus.

Composition

Peb paub tseeb tias: nws tsis yog qhov zais cia rau cov neeg nyeem tias cov hlau thiab carbon yog hlau. Ntshiab steel, kom meej. Txawm li cas los xij, cov khoom siv no tsis yog ib txwm haum rau kev siv. Nws yog txhawm rau txhim kho cov khoom qub ntawm cov hlau uas muaj ntau lub ntsiab lus los ntawm cov lus paub zoo tshaj plaws tau ntxiv rau nws cov muaj pes tsawg leeg, qhov muaj nyob hauv qhov muaj pes tsawg leeg hauv ib qho kev faib ua feem endows alloy nrog qee yam khoom xws li nce hnav tsis kam thiab oxidation tsis kam.

Steel 40ХН tsis muaj qhov zam, cov yam ntxwv ntawm qhov twgncaj qha ua raws los ntawm ligature muaj pes tsawg leeg, uas zoo li no:

• 0, 4% carbon;
• 0, 6% chromium;
• 0, 65% manganese;
• 0.27% silicon;
• 1, 2% npib tsib xee;
• 0, 3% tooj.

Alas, thev naus laus zis thev naus laus zis tsis tuaj yeem lav qhov tsis muaj qhov tsis zoo ntawm cov khoom tsis zoo hauv cov khoom ntawm 40XH hlau. Cov yam ntxwv vim lawv lub xub ntiag tsis deteriorate loj, txij li feem pua ntawm cov impurities tsis tshaj 0.035%.

Steel 40ХН: yam ntxwv

Kev siv 40KhN hlau ua cov khoom siv rau kev tsim cov khoom hnyav hnyav ntawm cov txheej txheem yog qhov qhia meej tshaj plaws uas cov hlau muaj qhov ntsuas muaj zog txaus. Thiab qhov no yeej muaj tseeb. Feem ntau ntawm cov master alloy nyob rau hauv muaj pes tsawg leeg ua rau kom cov yam ntxwv ntawm lub zog ntawm 40ХН steel, xws li hnav tsis kam, cuam tshuam lub zog, ductility, tsis kam mus rau siab kub, thiab kuj ua rau nws ntau resistant rau corrosion..

Analogues

Raws li ib txwm, yuav luag txhua yam hlau - cuab yeej, kev tsim kho lossis kev tsim qauv - yuav ib txwm muaj ntau qhov sib piv lossis hloov pauv ob qho tib si hauv lub tebchaws tsim khoom thiab txawv teb chaws.

Cia peb pib nrog cov hlau hauv tsev. Ntawm cov uas zoo sib xws yog:

• 40x.
• 35HGF.
• 50xn.
• 30XGWT.

Tab sis hauv kev lag luam txawv teb chaws koj tuaj yeem pom qee yam zoo sib xws. Piv txwv li:

• Tebchaws Meskas - 3135 lossis 3140N.
• Japan -SNC236.
• Tuam Tshoj - 40CrNi.
• Lub Tebchaws Yelemees - 1.5710 lossis 40NiCr6.

Zoo, tam sim no koj paub ntau ntxiv txog 40XH hlau, nws cov yam ntxwv ntawm tus kheej, thiab kev siv. Peb vam tias koj pom cov kab lus no muaj txiaj ntsig.
