Stainless hlau puas tuaj yeem kho cua sov?

Stainless hlau yog ib qho ntawm cov khoom siv dav siv hauv ntiaj teb, paub txog nws cov kev tiv thaiv corrosion, lub zog, thiab huv si. Tab sis cov lus nug uas nquag nug nyob rau hauv ob qho tib si industrial thiab engineering vajvoog yog:Stainless hlau puas tuaj yeem kho cua sov?Cov lus teb yog yog-tab sis nws nyob ntawm hom stainless hlau thiab cov txiaj ntsig xav tau.

Hauv tsab xov xwm no, peb tshawb xyuas cov hlau tsis muaj steel hlau twg tuaj yeem kho cua sov, txoj kev kho cua sov sib txawv, thiab qhov no cuam tshuam li cas rau kev ua haujlwm hauv kev siv tiag tiag.

Nkag siab txog hom Stainless Hlau

Txhawm rau nkag siab txog kev kho cua sov, nws yog ib qho tseem ceeb kom paub cov ntsiab lus ntawm stainless hlau:

1. Austenitic Stainless hlau(xws li, 304, 316)
   Cov no yog cov qib feem ntau, paub txog kev tiv thaiv corrosion zoo heev tab sistsis tuaj yeem hardened los ntawm kev kho cua sov. Lawv tsuas tuaj yeem ntxiv dag zog los ntawm kev ua haujlwm txias.

2. Martensitic Stainless hlau(eg, 410, 420, 440C)
   Cov qib notuaj yeem kho cua sovkom ua tiav siab hardness thiab lub zog, zoo ib yam li carbon steels.

3. Ferritic Stainless hlau(eg, 430)
   Ferritic hom muaj txwv hardenability thiabtsis tuaj yeem hardened los ntawm kev kho cua sov. Lawv feem ntau siv rau hauv tsheb txiav thiab cov khoom siv.

4. Duplex Stainless Hlau(eg, 2205, S31803)
   Cov hlau no muaj qhov sib xyaw microstructure ntawm austenite thiab ferrite. Thaum lawvtuaj yeem raug kev daws teeb meem annealing, lawvtsis haum rau hardeninglos ntawm cov txheej txheem kev kho cua sov.

5. Precipitation Hardening Stainless hlau(eg, 17-4PH / 630)
   Cov no tuaj yeem raug kho kom sov rau qib siab heev thiab feem ntau siv hauv aerospace thiab high-load structural applications.

At sakysteel ua, peb muab tag nrho cov loj stainless hlau pawg, nrog rau cov cua sov-kho martensitic thiab nag lossis daus hardening qib nrog tag nrho cov ntaub ntawv pov thawj thiab traceability.

Kev kho cua sov txoj kev rau Stainless hlau

Cov txheej txheem kev kho cua sov rau stainless hlau suav nrog kev tswj cov cua sov thiab cua txias kom hloov cov microstructure thiab txhua yam khoom. Hauv qab no yog cov txheej txheem kev kho cua sov tshaj plaws siv rau cov hlau stainless sib txawv:

1. Annealing

Lub hom phiaj:Relieves internal stress, softens cov hlau, thiab txhim kho ductility.
Cov Qib Kawm:Austenitic, ferritic, duplex stainless hlau.

Annealing muaj cua sov cov hlau mus rau qhov kub ntawm 1900-2100 ° F (1040-1150 ° C) thiab tom qab ntawd txias nws sai, feem ntau hauv dej los yog huab cua. Qhov no rov ua kom cov corrosion kuj thiab ua rau cov khoom yooj yim rau kev tsim lossis tshuab.

2. Hardening

Lub hom phiaj:Ua kom muaj zog thiab hnav tsis kam.
Cov Qib Kawm:Martensitic stainless hlau.

Hardening yuav tsum tau cua sov cov khoom mus rau qhov kub thiab txias (nyob ib ncig ntawm 1000-1100 ° C), ua raws li sai quenching nyob rau hauv roj los yog huab cua. Qhov no ua rau cov qauv nyuaj tab sis nkig, uas feem ntau ua raws li tempering los kho hardness thiab toughness.

3. Tempering

Lub hom phiaj:Txo brittleness tom qab hardening.
Cov Qib Kawm:Martensitic stainless hlau.

Tom qab hardening, tempering yog ua los ntawm reheating cov hlau mus rau ib tug qis kub (150-370 ° C), uas txo hardness me ntsis tab sis txhim kho toughness thiab usability.

4. Ntxoov Ntxov Hardening (Aging)

Lub hom phiaj:Ua tiav lub zog siab nrog zoo corrosion kuj.
Cov Qib Kawm:PH stainless hlau (piv txwv li, 17-4PH).

Cov txheej txheem no suav nrog kev daws teeb meem tom qab kev laus ntawm qhov kub qis (480-620 ° C). Nws tso cai rau qhov chaw kom ncav cuag lub zog siab heev nrog kev cuam tshuam tsawg heev.

Vim li cas Kub Kho Stainless Hlau?

Muaj ntau qhov laj thawj vim li cas cov tuam ntxhab thiab cov kws tsim khoom xaiv kev kho cua sov ntawm cov hlau tsis muaj steel:

• Nce Hardnessrau cov cuab yeej txiav, cov hniav, thiab qhov hnav-tiv taus
