Precipitation hardening stainless hlau, uas yog hu ua PH Steel, hais txog homstainless hlauuas ntxiv ntau hom thiab ntau ntawm cov khoom ntxiv, thiab ntau hom thiab ntau ntawm carbides, nitrides, carbonitrides thiab intermetallic compounds yog precipitated los ntawm cov nag lossis daus hardening txheej txheem. Cov nag lossis daus hardening stainless hlau tsis tsuas yog muaj lub zog siab, tab sis kuj muaj qhov zoo toughness thiab corrosion kuj. Cov nag lossis daus hardening stainless hlau tuaj yeem nrum ntawm pebpeev casting foundryraws li koj cov duab kos, kev xav tau thiab kev siv qhov xwm txheej.
Raws li cov ntsiab lus ntawm cov ntsiab lus tseem ceeb hauv cov nag lossis daus hardening stainless hlau thiab cov ntsiab lus hardening ntxiv, nag lossis daus hardnening stainless hlau tuaj yeem muab faib ua plaub pawg hauv qab no:
(1)Martensitic Precipitation Hardening Stainless hlau. Nws feem ntau muaj cov pa roj carbon tsawg dua 0.1%. Ua kom muaj zog los ntawm kev ntxiv cov khoom tawv tawv (tooj liab, txhuas, titanium thiab txhuas, thiab lwm yam) los ua kom tsis muaj zog. Cov ntsiab lus chromium feem ntau siab dua 17%, thiab qhov tsim nyog ntawm nickel ntxiv los txhim kho corrosion kuj.
(2)Maraging Precipitation Hardening Stainless hlau, nrog cov ntsiab lus carbon tsis siab tshaj 0.03% los xyuas kom meej lub toughness, corrosion kuj, weldability thiab workability ntawm martensite matrix, thiab 12% chromium los xyuas kom meej corrosion kuj. Tsis tas li ntawd, cov ntsiab lus alloy cobalt tau ntxiv los txhim kho cov kev kho cua sov ntawm cov hlau.
(3)Semi-Austenitic Precipitation Hardening Stainless Hlau, uas yog, kev hloov pauv nag lossis daus hardening stainless hlau, uas tsis muaj tsawg dua 12% chromium. Nws muaj cov ntsiab lus carbon tsawg, thiab txhuas ua nws lub ntsiab nag lossis daus hardening. Hom nag lossis daus hardening stainless hlau no muaj kev ua tau zoo tag nrho tshaj li martensitic nag lossis daus hardening stainless hlau.
(4)Austenitic Precipitation Hardening Stainless hlauyog ib qho stainless hlau nrog ruaj khov austenite qauv nyob rau hauv ob qho tib si quenched thiab aging xeev. Nws cov ntsiab lus npib tsib xee thiab manganese cov ntsiab lus siab, thiab cov ntsiab lus chromium siab dua 13% kom ntseeg tau zoo corrosion kuj thiab oxidation kuj. Nyob rau tib lub sijhawm, austenitic nag lossis daus hardening stainless hlau feem ntau ntxiv titanium, aluminium, vanadium lossis phosphorus raws li nag lossis daus hardening ntsiab lus, thiab ntxiv me me ntawm boron, vanadium, nitrogen thiab lwm yam khoom kom tau txais cov khoom zoo heev.
Precipitation hardening stainless hlau yog dav siv nyob rau hauv advanced industries. Piv txwv li, cov nag lossis daus hardening stainless hlau 17-4PH tuaj yeem siv los ua cov qauv hauv qab 370 ° C uas yuav tsum muaj kev tiv thaiv corrosion, hnav tsis kam, thiab lub zog siab.
