Steel 40X. Nws cov hauj lwm thiab uas

Steel yog ib tug ntawm cov tseem ceeb tshaj plaws yam ntxwv hlau. Nws tau pom ntau daim ntawv thov nyob rau hauv kev tsim kho, engineering thiab ntau lwm yam industries. Qhov no hlau ib tug ntau ntawm txawv hom, thiab lawv yog cov tag nrho sib txawv los ntawm txhua lwm yam ntxwv. 40X Steel - Lub Khoos Loos Tsev alloyed qib ntawm no cov ntaub ntawv uas. Thiab ntawm no peb yuav tham txog nws ntxiv.

Dhau li ntawm tus ib txwm impurities, lub cim 40x muaj ib tug tej yam muaj pes tsawg tus ntawm hais tias yog tswvcuab uas. Qhov no saib kuas tshwj xeeb cov yam ntxwv. No, raws li ib tug alloying caij chromium yog siv. Nws yog vim hais tias ntawm nws npav ntawm steel yog tam sim no tsab ntawv H.

muaj yog ib tug feature nyob rau hauv lub hlau - qhov no yog ib tug yooj yim weldability. Yog li ntawd 40X steel thaum lub sij hawm vuam txoj kev yog rhuab ^{mus rau} 300 ° C, thiab tom qab nws - thaum tshav kub kub kev kho mob. Nyob rau hauv tas li ntawd mus rau qhov feature, muaj ib tug ib txwm mus temper lub peev xwm thiab txawm flokenochuvstvietlnost.

40X steel muaj cov nram qab cov yam ntxwv:

- txheeb ze elongation - 13-17%;

- toughness - 800 kJ / sq. meter;

- tensile zog - 900 MPa.

Nws muaj lwm yam nta uas yog raug rau no steel qib :

- endurance txwv ntawm lub heev;

- tseem mus nqa tawm txiav ua txoj kev, los yog los ntawm Vuam nyob rau hauv siab;

- kuj rau kev nkhaus thiab decarburized at-tshav kub.

Rau tag nrho ntawm cov ntaub ntawv yog cov tseem ceeb tshaj plaws zog. Lawv cia cov kev siv ntawm steel 40X nyob rau hauv lub engineering kev lag luam.

Thaum forging steel ntawm lub hom kub ntawm qhov pib ntawm tus txheej txheem yog 1250 ^{° C,} thiab nyob rau thaum xaus - 800 ° ^C.

Heev feem ntau, qhov no steel yog siv nyob rau hauv qhov siv thiab ua upgradable qhov chaw, uas yog yus los siab zog. Nws cov khoom xws li plungers, koob, axles, shafts, rings, ncej pinion, crank thiab cam shafts, screws, ib nrab-axis ntsia, bushings, spongy rims, lub mandrel thiab lwm yam tsim nyog cov khoom.

40 steel yog dav siv rau zus tau tej cov kais dej, xyaum, cov ntaub ntawv. Raws li koj tau pom, nws yog tag nrho cov cuab yeej uas kuv tau ua hauj lwm rau ib lub uas tsis muaj kev ceev thiab cov cua kub kub yog tsis ntau tshaj li 2000 degrees. Cov khoom uas rods uas muaj ib tug yeej cross-section. Lawv yog ua nyob rau hauv raws li GOST 5950-2000.

Nyob rau hauv cov ntaub ntawv yog tias koj xav tau steel, uas muaj xeb kuj, nws yog tsim nyog them sai sai mus rau lub hom 40X13. Qhov no stainless corrosion-resistant hlau. Kuj mus xeb nws acquires tom qab quenching, vim hais tias nyob rau hauv cov ntaub ntawv no yog kiag li yaj carbide. Steel 40X13 ua nyob rau hauv induction rauv taws nte, thiab Arc qhib hom. Cov uas ua cov ntaub ntawv uas twb txig deformed ntawm ib tug kub ^ntawm 850-1100 C. Thiab kom tsis txhob cracking, cua sov thiab tom ntej txias yuav tsum tau nqa tawm maj mam.

Thaum kawg nws yog tsim nyog los xav kom cov neeg muas zaub. Qhov zoo tshaj plaws ntawm tag nrho cov steel 40s, raws li zoo raws li cov khoom ua los ntawm nws mus yuav los ntawm lub manufacturers ncaj qha. Muaj yog ib txwm ib tug nqi yuav tsis muaj ntxiv nqi, vim hais tias koj "tau nyob ib ncig ntawm" intermediaries. Tsis tas li ntawd, cov khoom yuav ua tau los ntawm koj kom tsis. Nyob rau hauv tas li ntawd, cov nroj tsuag feem ntau muab nyiaj cheb rau lag luam wholesale buyers, raws li zoo raws li ib tug guarantee ntawm zoo khoom. Thiab nyob rau hauv cov ntaub ntawv ntawm kev sib yuav, koj yuav paub tias leej twg hu tuaj.
