Carbon Steel Series

 

Q235 Hlau: Qhov no yog cov pa roj carbon monoxide steel thiab yog siv dav. Nws cov khoom siv kho tshuab tuaj yeem ua kom zoo dua los ntawm quenching thiab tempering. Thaum lub sij hawm quenching, cov cua kub feem ntau yog nyob ib ncig ntawm 850 - 900 degree, thiab dej - txias los yog roj - txias yog saws. Tom qab ntawd, tempering yog nqa tawm ntawm 600 - 650 degree . Tom qab kev kho mob zoo li no, nws lub zog tuaj yeem txhim kho tau zoo. Lub zog tsis tshua muaj zog (kwv yees li 235 MPa) tuaj yeem nce mus rau qee qhov, thiab cov tawv tawv kuj tuaj yeem txhim kho. Nws tuaj yeem siv los tsim qee yam khoom siv yooj yim lossis tsim cov khoom siv uas muaj qee yam kev xav tau rau lub zog thiab toughness.

 

45 - Hlau (High - Zoo Carbon Structural Steel): Cov ntsiab lus carbon yog hais txog 042 - 0.50%. Nws tuaj yeem dhau los ua ntau yam kev kub ntxhov - kev kho mob. Piv txwv li, quenching kub yog 820 - 840 degree . Tom qab cov roj - quenching, lub hardness yog heev nce. Yog tias tempering tau ua tiav, qhov sib txawv ntawm cov khoom siv sib txawv tuaj yeem tau txais raws li qhov sib txawv ntawm qhov kub thiab txias (piv txwv li, qhov ntsuas kub qis yog 150 - 250 degree, qhov nruab nrab kub tempering yog 350 - 500 degree , thiab qhov kub siab tempering kub yog 500 - 650 degree ). Tsawg-kub tempering tuaj yeem tswj tau siab hardness thiab hnav tsis kam thiab siv los tsim cov cuab yeej txiav, thiab lwm yam .; nruab nrab - qhov kub thiab txias tempering tuaj yeem tau txais kev txwv ntau dua thiab siv los tsim cov khoom siv; high-temperature tempering tuaj yeem tau txais cov khoom zoo txhua yam thiab siv los tsim cov shafts thiab lwm yam khoom siv tshuab.

 

Alloy Steel Series

 

40Cr Steel (Alloy Structural Steel): Nws muaj chromium thiab muaj zog hardenability. Qhov kub quenching feem ntau yog 850 - 880 degree, nrog roj - txias, thiab tempering kub yog 500 - 600 degree . Tom qab xws li cua sov - kev kho mob, nws lub zog, toughness thiab hnav tsis kam yuav ua tau zoo - sib npaug. Cov hlau no feem ntau yog siv los tsim cov khoom siv hluav taws xob tseem ceeb xws li semi-axles ntawm lub tsheb thiab cov spindles ntawm cov cuab yeej siv tshuab, vim tias cov khoom no yuav tsum tau nqa cov khoom loj thiab torques thiab tseem muaj cov kev xav tau siab rau kev qaug zog.

 

38CrMoAl hlau: Nws yog nitriding hlau. Ua ntej kev kho nitriding, quenching (lub quenching kub yog hais txog 940 degree, nrog roj - txias) thiab high-temperature tempering (lub tempering kub yog hais txog 640 degree) feem ntau yog ua. Tom qab kev kho nitriding, txheej txheej nitride nyuaj heev yog tsim rau ntawm nws qhov chaw, uas tuaj yeem txhim kho qhov tawv tawv thiab hnav tsis kam, thaum cov tub ntxhais tseem tuav tau zoo toughness. Nws feem ntau yog siv los tsim lub tshuab ua haujlwm siab - cov cuab yeej spindles, tho txawv tuav thiab lwm yam uas yuav tsum tau muaj qhov siab tawv, hnav tsis kam thiab qhov tseeb qhov tseeb.

Stainless hlau Series

 

304 Stainless hlau: Txawm hais tias nws muaj kev tiv thaiv corrosion zoo los ntawm nws tus kheej, nws qhov kev ua tau zoo tuaj yeem ua tau zoo dua los ntawm kev kho cov tshuaj (suab cua sov rau 1050 - 1150 degree thiab txias ceev). Kev kho tshuaj tuaj yeem ua rau cov carbides yaj tag nrho, tsis txhob cuam tshuam kev cuam tshuam ntawm intergranular, thiab txhim kho nws lub zog thiab toughness. Nws yog dav siv nyob rau hauv qee yam khoom siv tshuaj thiab khoom noj khoom haus - cov cuab yeej ua haujlwm uas yuav tsum tau ua kom muaj zog thiab nyob rau hauv ib puag ncig corrosive.

 

420 Stainless hlau (Martensitic Stainless hlau): Nws muaj cov ntsiab lus siab carbon. Los ntawm quenching (lub cua sov kub yog 1000 - 1050 degree , nrog roj - txias los yog cua - txias) thiab tempering (lub tempering kub yog kho raws li kev xav tau ntawm 200 - 600 degree), nws cov cuab yeej cuab tam tuaj yeem hloov pauv tau. . Tom qab quenching, lub hardness yog heev nce. Tom qab tempering, qhov sib npaug ntawm toughness thiab lub zog tuaj yeem hloov kho. Nws yog siv los tsim cov cuab yeej txiav, cov cuab yeej kho mob thiab lwm yam khoom uas yuav tsum muaj rau hardness thiab corrosion kuj.
