Cov Khoom Siv Cov Khoom Siv Rau Cov Khoom Kho Vajtse

Cov cuab yeej kho vajtse feem ntau yog ua los ntawm cov hlau, tooj liab, thiab roj hmab

Hlau: Feem ntau ntawm cov cuab yeej kho vajtse yog ua los ntawm cov hlau

Tooj liab: qee cov pab cuam kub siv tooj liab li cov khoom siv

Roj Hmab: Qee cov cuab yeej kub siv roj hmab ua khoom siv

Yog tias cov tshuaj lom neeg tshuaj tau faib, nws tuaj yeem suav tau raws li ob pawg loj ntawm cov hlau thiab hlau hlau.

Nws tau muab faib ua peb pawg: qauv hlau, cuab yeej hlau thiab tshwj xeeb steel.

Raws li cov khoom zoo, peb hom hlau zoo li qub, cov hlau ua kom zoo tau raug cais.

Cov Hlau Hlau

Cov ntsiab lus carbon cov ntsiab lus ntawm cov roj carbon hlau hauv qab 1.5%, cov pa roj carbon, 0.25% cov pa roj carbon, 0.25% cov pa roj carbon hlau tsawg dua lossis cov pa roj carbon thiab cov roj carbon hlau ntau dua 0.6%.

Vim tias phosphorus thiab leej faj tuaj yeem nce tus brittleness ntawm tsawg dua lossis cov ntsiab lus ntawm phosphorus thiab leej faj hauv phosphorus thiab leej faj hauv hlau yuav tsum tau txhais thaum qhov zoo yog cais. Zoo tib yam hlau, muaj tsawg dua 0.045% cov ntsiab lus ntawm cov neeg sab nrauv tsawg dua 0.055%. Cov khoom siv hlau zoo, phosphorus cov ntsiab lus tsawg dua 0.04%, cov lus faj sulfur ntawm tsawg dua 0.045%. Cov neeg Sulphur cov ntsiab lus ntawm Tool Steel, P = 0.04% feem. Nyob rau hauv high-qib steel, phosphorus thiab Sulphur cov ntsiab lus yuav tsum tau tsawg dua 0.03%.

Cov txheej txheem carbon txheej txheem hlau yog siv rau kev tsim khoom ntau yam (xws li cov kwj deg, thiab lwm yam., Feem ntau yog cov roj carbon thiab nruab nrab ntawm cov hlau.

Carbon Tool steel yog lub ntsiab lus tseem ceeb rau ua ntau cov cuab yeej, ntsuas cov cuab yeej, kov cov cuab yeej thiab cov cuab yeej hardware, feem ntau yog cov pa roj carbon hlau. Carbon Tool steel hlau nrog "T", raws li T7 SHAR GARBON POB GARBONS TUAM STEEL PVC 0.7%. Cov Khoom Siv Zoo Carbon Tool yog sawv cev los ntawm "A" tom qab tus lej, xws li "T7 A".

Chav kawm hlau. Qhov no ntawm cov hlau yog muab los ua kev lav ntawm cov khoom siv mechanical. Nrog rau tag nrho ntawm 1-7 qib, ntau dua tus hlau, ntau dua cov txiaj ntsig lub zog thiab tensile lub zog, tab sis tus me dua qhov elongation.

Chav Kawm B steel, hom hlau no tau muab los ntawm cov tshuaj lom neeg muaj pes tsawg leeg. Nrog rau tag nrho ntawm 1-7 qib, ntau dua tus lej b steel, qhov ntau dua cov ntsiab lus carbon.

Alloy Steel

Txhawm rau txhim kho cov khoom siv cov khoom siv, txheej txheem, lub cev nqaij daim tawv thiab tshuaj lom neeg ntawm cov hlau thaum smelting, uas yog hu ua alosoy steel. Qhov nruab nrab cov ntsiab lus ntawm ntau dua 1% alloy tuam steel thaum cov ntsiab lus carbon, tsawg dua 1%, nrog tsawg dua 1%

Tag nrho cov nyiaj ntawm cov khoom siv hauv hlau hu ua <5% tsawg dua li cov hlau, 5%, tag nrho cov nyiaj ntawm cov hlau loj.

Alloy hlau tuaj yeem txais cov khoom siv neeg kho tshuab uas nyuaj rau kev ua tiav hauv cov roj carbon steel.

Chromium: nce qhov nyuaj ntawm cov hlau thiab txhim kho cov hnav tsis kam thiab nce lub hardness.

Vanadium: Nws muaj kev txhawb nqa zoo rau kev txhim kho lub hardness, coj kev tawm tsam thiab tawv ntawm cov hlau, tshwj xeeb tshaj yog rau kev txhim kho cov hlau tsis kam ntawm cov hlau.

Mo: Nws tuaj yeem txhim kho qhov nyuaj thiab qhov ruaj khov ntawm cov hlau, ua kom cov qoob loo tsis zoo thiab txhim kho lub zog thiab tawv ntawm cov hlau.

Cov hlau siv hauv cov cuab yeej kho vajtse

Vim tias cov kws tshaj lij tshwj xeeb cov khoom siv ntawm cov hlau alloy steel, lub alloy tuam steel hlau feem ntau yog siv nyob rau hauv nruab nrab thiab theem siab qib kev ua haujlwm. Nws yog feem ntau siv rau lub ncu kho cov nroj tsuag, tsheb loj, fais fab cog thiab kev lag luam uas muaj cov cuab yeej siv siab thiab siab dua cov cuab yeej xav tau.

Carbon Tool Steel feem ntau yog siv hauv cov cuab yeej theem qis, uas muaj qhov zoo ntawm tus nqi qis. Nws yog feem ntau haum rau cov neeg siv cuab tam nrog tsev neeg uas muaj kev siv roj tsawg thiab tsis muaj kev thov siab rau cov cuab yeej.

S2 alloy steel (feem ntau yog siv rau kev ua ntsia hlau, ntsia hlau)

Cr mo hlau (feem ntau siv los ua cov ntsia hlau)

(feem ntau yog siv nyob rau hauv kev tsim cov chrome vanadium lub tes tsho, wrenches, muaj tus)

Carbon Steel (feem ntau yog siv rau cov cuab yeej qis)
