2205 Duplex Stainless Alloy Phaj

2205 Duplex Stainless Hlau Phaj yog cov khoom siv dav siv duplex (austenitic-ferritic) stainless hlau uas muaj kev sib xyaw ua ke zoo ntawm lub zog siab, zoo corrosion kuj, thiab tsis kam rau kev ntxhov siab corrosion cracking (SCC). Qhov sib npaug dual-theem microstructure ntawm ferrite thiab austenite muab qhov zoo tshaj plaws ntawm ob lub ntiaj teb: lub toughness thiab ductility ntawm austenitic steels thiab lub zog siab thiab tsis kam rau SCC ntawm ferritic steels.

Kev ua haujlwm

Kub txoj kev

Ua kom qis dua 600 degree F yog pom zoo thaum twg los tau. Thaum kub sib sau yog yuav tsum tau, lub workpiece yuav tsum tau rhuab uniformly thiab ua hauj lwm nyob rau hauv qhov ntau ntawm 1750 mus rau 2250 degree F. Alloy 2205 duplex stainless hlau phaj yog heev mos ntawm cov kub thiab yog yooj yim tsim. Saum toj no ntau yam, 2205 yuav raug kub tearing. Tam sim ntawd hauv qab no ntau yam, lub austenite yuav muaj zog dua cov ferrite thiab tej zaum yuav ua rau tawg, ib qho kev phom sij rau "txias" npoo. Hauv qab 1700 degree F tuaj yeem tsim sai ntawm cov theem intermetallic vim yog kev sib xyaw ntawm qhov kub thiab txias. Thaum twg kub sib sau ua tiav, nws yuav tsum tau ua raws li tag nrho cov tshuaj anneal ntawm 1900 degree F yam tsawg kawg nkaus thiab ceev quench kom rov qab theem sib npaug, toughness, thiab corrosion kuj. Kev ntxhov siab tsis tas yuav tsum tau lossis pom zoo; Txawm li cas los xij, yog tias nws yuav tsum tau ua, cov khoom siv yuav tsum tau txais kev daws teeb meem tag nrho ntawm 1900 degree F yam tsawg kawg nkaus, ua raws li qhov txias txias los yog dej quenching.

Alloy 2205 duplex stainless hlau phaj yog yooj yim sheared thiab txias tsim ntawm cov khoom haum rau ua hauj lwm stainless hlau. Txawm li cas los xij, vim yog lub zog siab thiab ua haujlwm nrawm ntawm 2205 duplex stainless hlau phaj, quab yuam ntau dua li cov rau austenitic steels yuav tsum tau txias rau nws. Tsis tas li vim muaj lub zog siab, qhov nyiaj pub me me yuav tsum tau ua rau lub caij nplooj ntoo hlav.

Kev kho cua sov

Alloy 2205 duplex stainless hlau phaj yuav tsum tau annealed ntawm 1900 degree F yam tsawg kawg nkaus, ua raws li los ntawm ceev ceev txias, lub hom phiaj los ntawm dej quenching. Txoj kev kho no siv rau ob qho tib si tshuaj annealing thiab kev ntxhov siab. Kev kho kev ntxhov siab ntawm qhov kub qis ua rau muaj kev pheej hmoo ntawm nag lossis daus ntawm cov theem cuam tshuam ntawm intermetallic lossis nonmetallic theem.

Machineability

Nrog high-speed steel tooling, 2205 duplex stainless hlau phaj tej zaum yuav machined ntawm tib feeds thiab speeds li Alloy 316L. Thaum siv cov cuab yeej carbide, kev txiav ceev yuav tsum raug txo los ntawm 20% piv rau qhov nrawm rau Alloy 316L. Cov cav tov muaj zog thiab nruj mounting ntawm cov cuab yeej thiab qhov chaw yog qhov tseem ceeb.

Vuam

Alloy 2205 duplex stainless hlau phaj muaj qhov zoo weldability. Lub hom phiaj ntawm welding 2205 yog qhov vuam hlau thiab tshav kub-cuam tshuam cheeb tsam (HAZ) khaws cov corrosion kuj, lub zog, thiab toughness ntawm lub hauv paus hlau. Kev vuam ntawm 2205 tsis yog qhov nyuaj, tab sis nws yog ib qho tsim nyog los tsim cov txheej txheem vuam uas ua rau muaj kev sib npaug zoo tom qab vuam thiab yuav tsis txhob muaj nag lossis daus ntawm kev puas tsuaj ntawm cov txheej txheem intermetallic lossis nonmetallic.

Alloy 2205 duplex stainless hlau phaj tuaj yeem welded los ntawm: GTAW (TIG); GMAW (MIG); SMAW ("stick" electrode); SAW; FCW; and PAW.
