Alloy Steel

Alloy Steel
Kev faib tawm ntawm Alloy Steel
Raws li Alloy keeb kwm ntsiab lus
Tsawg alloy steel (tag nrho alloy alloy keeb yog tsawg dua 5%), nruab nrab Alloy Element yog 5%, High Alloy Element yog siab tshaj 10%).
Raws li Alloy keeb kwm muaj pes tsawg leeg
Chromium Hlau (CR-F-C), Chromium-Npib (CRANGINES HLAU (MN-FE-C), LICH-MANGANESE STEEL (SI-MN-FE-c).
Raws li cov qauv me me los yog cov qauv nrum
Pharlite hlau, Martensite hlau, Ferrite hlau, Austenite steel, ledeburite steel.
Raws li siv
Allolo qauv qauv hlau, alloy tuam hlau, tshwj xeeb cov khoom siv hlau.
Alloy Steel Numbering
Cov ntsiab lus carbon yog qhia los ntawm tus lej thaum pib ntawm qib. Nws yog cov ntsiab lus uas cov ntsiab lus carbon yog qhia los ntawm tus lej (ob tus lej) hauv cov chav ua haujlwm ntawm ib txhiab rau cov cuab yeej hlau thiab kev ua haujlwm tshwj xeeb steel, thiab cov ntsiab lus carbon tsis tau qhia thaum cov ntsiab lus carbon ntawm Tool Steel tau tshaj li 1%.
Tom qab qhia cov ntsiab lus carbon, cov khoom siv tshuaj lom neeg ntawm lub ntsiab yog siv los qhia txog cov khoom lag luam tseem ceeb hauv cov hlau. Cov ntsiab lus yog qhia los ntawm tus naj npawb tom qab nws. Thaum cov ntsiab lus nruab nrab yog tsawg dua 1.5%, tsis muaj lej cim. Thaum cov ntsiab lus nruab nrab yog 1.5% rau 2.49%, 2.5% rau 3.49%, thiab lwm yam. 2, 3, thiab lwm yam yog khij raws li.
Allolo qauv steel 40cr muaj cov ntsiab lus nruab nrab ntawm 0.40%, thiab cov ntsiab lus ntawm lub ntsiab alloy alloy alloy alloy alloy alloy alloy alloy alloy alloy alloing. Tsawg dua 1.5%.
Alloy tuam cuab tam steel 5crm
Cov hlau tshwj xeeb yog cim nrog cov xov tooj ntawm Suav ntawm lawv cov kev siv. Piv txwv li: Cov kabmob pob cov hlau, cim nrog "G" ua ntej tus lej Steel. GCR15 qhia tias cov kabmob pob nrog cov ntsiab lus carbon uas muaj txog li ntawm 1.5% (qhov no yog qhov tshwj xeeb, cov ntsiab lus chromium yog qhia hauv ib txhiab ib txhiab). Y40MN qhia cov hlau dawb uas muaj cov ntsiab lus carbon ntawm 0.4% thiab lwm yam ntxiv rau qhov kawg ntawm cov hlau los qhia qhov no, xws li 20cr2NI4.
Alloying ntawm cov hlau
Tom qab cov khoom siv alloy tau ntxiv rau cov hlau, cov khoom siv pib ntawm cov hlau, hlau thiab carbon, yuav cuam tshuam nrog cov khoom ntxiv ntxiv. Lub hom phiaj ntawm cov khoom siv alloy yog txhawm rau txhim kho cov qauv thiab cov khoom siv hlau los ntawm kev siv cov kab kos duab hlau thiab kev kho cua sov.
Kev sib cuam tshuam ntawm cov ntsiab lus alloy thiab hlau thiab carbon
Tom qab cov khoom siv allooy tau ntxiv rau cov hlau, lawv muaj nyob hauv cov hlau feem ntau hauv peb hom. Qhov ntawd yog: tsim cov kev daws teeb meem nrog hlau; tsim cov carbides nrog carbon; thiab kev sib sau intermetallic tebchaw hauv highoy steel.

Alloy Qauv Hlau
Cov hlau siv los tsim cov tseem ceeb engineering vaj tswv thiab tshuab qhov chaw hu ua alloy txheej txheem hlau. Muaj ntau cov txheej txheem tsawg-alloy qauv hlau, alloy carburizing hlau, alloy quenched thiab tempered steel, thiab cov kabmob pob.
Tsawg-alloy qauv txheej txheem
1. Siv tsuas yog siv hauv kev tsim cov choj, nkoj, Boilers, roj kub, roj thiab roj loj, khoom loj, thiab lwm yam.
2. Kev xav tau kev xav tau
(1) Lub zog siab: feem ntau, nws cov txiaj ntsig lub zog yog saum 300mpa.
(2) qhov siab tawv: Lub elongation yuav tsum yog 15% rau 20%, thiab chav tsev kub cuam tshuam nyuaj yog ntau dua 600KJ / M. Rau cov welded loj loj, cov pob txha siab dua cov pob txha tawv muaj zog kuj yuav tsum tau ua.
(3) Kev tsim txoj kev ua haujlwm zoo nkauj thiab kev ua kom txias.
(4) Qeeb txias txias txias txias txias.
(5) zoo corrosion tsis kam.
3. Cov Cwj Pwm
(1) Cov pa roj carbon tsawg: Vim tias qhov kev ua kom muaj zog, weldability thiab kev ua si tov, nws cov ntsiab lus carbon tsis pub tshaj 0.20%.
(2) Ntxiv cov khoom siv alloy tsuas yog sib xyaw ntawm manganese.
(3) Ntxiv cov zauv uas muaj niobium, titanium lossis vanadium (vanadium
Ib qho ntxiv, ntxiv me me ntawm tooj liab (≤0.4%) thiab phosphorus (txog 0.1% tuaj yeem txhim kho corrosion tsis kam. Ntxiv ib qho me me ntawm lub ntiaj teb tsis tshua muaj peev xwm desulfurize thiab degas, purify cov hlau, thiab txhim kho cov tawv nqaij, thiab txhim kho kev ua tiav thiab ua tiav.
4. Siv cov hlau qis-alloy qauv qauv hlau
16MN yog qhov siv tau tshaj plaws thiab tsim cov hlau hauv kuv lub teb chaws tsawg-alloy high-zog hlau. Cov qauv hauv kev siv yog zoo-nplej ferrite-petosite, thiab lub zog yog li ntawm cov roj carbon los ntawm cov roj ntsha steel Q235, thiab cov atmidpheric corrosion yog 20% ​​rau 38% siab dua.
15Mnvn yog cov siv hlau siv feem ntau hauv cov hlau-qib nruab nrab. Nws muaj lub zog muaj zog, thiab zoo toughness, weldability thiab tsawg-qhov kub. Nws yog dav siv nyob rau hauv kev tsim cov qauv loj xws li choj, boilers, thiab cov nkoj.
Thaum cov qib ua tiav ntau dua li 500mpa, ferrite thiab cov hlawsite qauv yog qhov nyuaj kom tau raws li cov cai, yog li cov pa roj carbon bainite tsim. Ntxiv cov khoom xws li Cr, Mo, thiab B yog qhov zoo kom tau txais Bainite cua txias, ua rau lub zog loj dua, thiab cov yas thiab vuam cov kev kawm kuj zoo dua. Nws yog feem ntau siv nyob rau hauv high-siab boilers, muaj siab huv si ntim, thiab lwm yam.
5. Kev kho cua sov
Hom hlau no feem ntau siv nyob rau hauv lub xeev kub-txias lub xeev thiab tsis xav tau kev kho cua sov tshwj xeeb. Microstructure hauv kev siv lub xeev feem ntau ferrite + tunostite.
