Alloy 17-4PH yog nag lossis daus hardening martensitic stainless hlau nrog Cu thiab Nb/Cb ntxiv. Cov qib sib xyaw ua ke siab zog, hardness (txog 572 degree F / 300 degree), thiab corrosion kuj. Cov khoom siv kho tshuab tuaj yeem ua kom zoo nrog kev kho cua sov. Lub zog tawm los siab heev txog li 1100-1300 MPa (160-190 ksi) tuaj yeem ua tiav.
General Properties
Alloy 17-4PH (UNS S17400), Hom 630, yog chromium-nickel-copper nag lossis daus-hardening martensitic stainless hlau nrog ib qho ntxiv ntawm niobium. 17-4PH muab lub zog siab thiab hardness nrog corrosion kuj zoo.
Cov hlau yog muab tso rau hauv qhov kev daws teeb meem annealed (Condition A). Nws yuav tsum tsis txhob siv ntawm qhov kub siab tshaj 572 degree F (300 degree) lossis rau kev pabcuam cryogenic. Cov khoom siv zoo tshaj plaws tuaj yeem tau txais los ntawm kev siv cov alloy rau hnub nyoog hardening kev kho cua sov. Kev kho cua sov hauv 900 degree F (482 degree) ua rau lub zog siab tshaj plaws.
Qhov corrosion kuj ntawm Alloy 17-4PH yog piv rau 304 stainless hlau nyob rau hauv feem ntau ib puag ncig, thiab feem ntau yog superior rau 400 series stainless hlau. Nws yog siv nyob rau hauv daim ntawv thov qhov twg ua ke ntawm nruab nrab corrosion kuj thiab txawv txawv zog yuav tsum tau.
Alloy 17-4PH tuaj yeem yooj yim welded thiab ua tiav los ntawm cov qauv kev tsim khoom hauv khw. Nws yog magnetic.

Qhov corrosion kuj ntawm Alloy 17-4PH yog piv rau 304 stainless hlau nyob rau hauv feem ntau ib puag ncig, thiab feem ntau yog superior rau 400 series stainless hlau. Nws yog siv nyob rau hauv daim ntawv thov qhov twg ua ke ntawm nruab nrab corrosion kuj thiab txawv txawv zog yuav tsum tau. Alloy 17-4PH muaj corrosion kuj piv rau 304L hauv qee yam tshuaj, khoom noj siv mis, khoom noj, ntawv thiab roj av.
Alloy 17-4PH nyob rau hauv cov tshuaj-annealed mob (Txoj Cai A) yuav tsum tsis txhob muab tso rau hauv kev pab. Cov hlau yog raug rau nkig tawg thiab ntau rhiab heev rau chloride kev nyuaj siab corrosion cracking dua li cov khoom muaj hnub nyoog.
Yog hais tias muaj kev pheej hmoo ntawm chloride kev nyuaj siab corrosion cracking yog tam sim no cov laus laus kub yuav tsum tau xaiv tshaj 1022 degree F (550 degree), nyiam dua 1094 degree F (590 degree). 1022 degree F (550 degree) yog qhov pom zoo tempering kub hauv kev pabcuam chloride. 1094 degree F (590 degree) yog nyiam nyob rau hauv H2S media.
Alloy 17-4PH yog nyob rau hauv crevice corrosion thiab pitting nres thaum raug rau cov dej hiav txwv stagnation ntawm lub sij hawm.

Txias txoj kev
Alloy 17-4PH muaj kev txwv kev ua kom txias txias. Cold forming tsuas yog ua tau rau ntawm daim hlau nyob rau hauv tag nrho annealed mob. Kev ntxhov siab corrosion kuj yog txhim kho los ntawm kev laus dua ntawm cov nag lossis daus hardening kub tom qab ua haujlwm txias.
Kub txoj kev
Kub sib npaug ntawm 1742 - 2192 degree F (950 - 1200 degree). Ib qho kev daws teeb meem tag nrho, txias qis dua 76 degree F (25 degree) thiab kev laus ntawm qhov ntsuas kub yuav tsum tshwm sim tom qab kub sib sau. Tom qab tsim kev kho cua sov yuav tsum yog ib qho kev ua haujlwm ntawm cov khoom siv kho tshuab uas xav tau.
Tshuab dhos
Alloy 17-4PH tuaj yeem ua tau rau hauv ob qho tib si cov tshuaj kho thiab nag lossis daus hardened. Cov yam ntxwv ntawm machining yuav txawv raws li qhov hardness ntawm cov hlau. Cov cuab yeej siv ceev ceev tau txais, tab sis cov cuab yeej carbide nyiam dua. Txheem lubrication yuav tsum tau siv. Dimensional hloov raws li kev kho cua sov yuav tsum tau coj mus rau hauv tus account yog hais tias yuav tsum tau nruj heev tolerances.
Txiav
Kev ua haujlwm thermal xws li plasma txiav yuav tsum zam. Mechanical tej hauj lwm xws li bandsaw, abrasive waterjet, shearing thiab machining yog nyiam.
Vuam
Alloy 17-4PH tuaj yeem nkag tau yooj yim los ntawm cov txheej txheem txheem feem ntau suav nrog SMAW, GTAW, PAW thiab GMAW.
