17-4 stainless yog lub hnub nyoog-hardening martensitic stainless combining siab zog nrog corrosion kuj ntawm stainless hlau.Hardening yog ua tiav los ntawm ib lub sij hawm luv luv, kev kho mob tsawg-kub yooj yim.Tsis zoo li cov pa martensitic stainless hlau, xws li hom 410, 17-4 yog weldable heev.Lub zog, corrosion kuj thiab yooj yim fabrication yuav ua tau 17-4 stainless ib tug nqi-zoo hloov rau siab zog carbon steels thiab lwm yam stainless qib.
Ntawm cov tshuaj kho qhov kub thiab txias, 1900 ° F, cov hlau yog austenitic tab sis tau hloov mus rau cov qauv qis-carbon martensitic thaum lub caij txias rau hauv chav sov.Qhov kev hloov pauv no tsis ua tiav kom txog thaum qhov kub poob mus rau 90 ° F.Tom qab cua sov rau qhov kub ntawm 900-1150 ° F rau ib mus rau plaub teev nag lossis daus ntxiv dag zog rau cov hlau.Qhov kev kho hardening no kuj tempers cov qauv martensitic, nce ductility thiab toughness.

Vim li cas 17-4PH?
•Ib qho yooj yim los kho cov theem lub zog, uas yog los ntawm kev hloov pauv hauv cov txheej txheem kho cua sov los kho martensite theem transformation thiab kev laus
kev kho cov hlau ua nag lossis daus hardening theem.
•Corrosion qaug zog kuj thiab dej tsis kam.
•Vuam: Nyob rau hauv cov xwm txheej ntawm cov khoom, kev laus los yog overageing, lub alloy yuav welded nyob rau hauv txoj kev, tsis muaj preheating.
Yog hais tias xav tau lub zog vuam ze rau cov hlau lub zog ntawm kev laus hardened, ces cov hlau yuav tsum yog cov khoom tov thiab kev laus kho tom qab vuam.
Cov alloy no kuj tsim nyog rau brazing, thiab qhov zoo tshaj plaws brazing kub yog cov tshuaj kub.
•Corrosion kuj： Alloy corrosion kuj yog superior rau lwm yam txheej txheem hardenable stainless hlau, nyob rau hauv cov dej zoo li qub yooj yim raug kev txom nyem los ntawm corrosion los yog tawg. Nyob rau hauv cov roj av chemical kev lag luam, zaub mov ua thiab ntawv kev lag luam nrog zoo corrosion kuj.
17-4PH Daim ntawv thov teb:
•Offshore platforms, lub dav hlau helicopter, lwm lub platforms.
•Kev lag luam zaub mov.
•Pulp thiab ntawv kev lag luam.
•Qhov chaw (turbine hniav).
•Mechanical qhov chaw.
•Nuclear khib nyiab.
17-4PH alloy yog precipitated, quenched, martensitic stainless hlau nrog lub zog siab, hardness thiab corrosion kuj.Nws tsis tuaj yeem siv ntawm qhov kub siab tshaj 300 0C.(572 oF) lossis kub qis heev.Nws muaj qhov zoo corrosion tsis kam rau huab cua thiab dilute acids lossis ntsev.Nws cov corrosion kuj zoo ib yam li 304 thiab 430.感兴趣，请与我们联系。期待您的回复Phone/whatsapp Ib: 0086-15921454807
