Stainless Hlau Phaj Siab Nickel Alloy 1.4876 Corrosion Resistant Alloy
1.4876 yog Fe Ni Cr raws li cov khoom siv ntxiv dag zog deformed kub corrosion resistant alloy. Nws yog siv hauv qab 1000 ℃. 1.4876 corrosion resistant alloy muaj zoo heev kub corrosion kuj thiab cov txheej txheem zoo, zoo microstructure stability, zoo ua thiab vuam kev ua tau zoo. Nws yog ib qho yooj yim los tsim los ntawm kev ua haujlwm txias thiab kub. Nws yog qhov tsim nyog rau kev ua cov khoom uas yuav tsum muaj qhov kub thiab txias thiab ua haujlwm ntev nyob rau hauv qhov hnyav corrosive nruab nrab.
1.4876 corrosion resistant alloy muaj kev ntxhov siab zoo corrosion tsis kam, kev nyuaj siab corrosion tsis kam nyob rau hauv dej chloride, corrosion kuj rau chav, huab cua thiab carbon dioxide sib tov, thiab zoo corrosion kuj rau organic acids xws li HNO3, HCOOH, CH3COOH thiab propionic acid.
1.4876 corrosion resistant alloy thawj coj qauv muaj ib tug series ntawm cov qauv nyob rau hauv ntau lub teb chaws. Cov qauv txawv teb chaws feem ntau yog UNS, ASTM, AISI thiab din, thaum peb lub teb chaws cov qauv muaj xws li hom qauv GB / t15007, rod standard GB / t15008, phaj standard GB / t15009, yeeb nkab standard GB / t15011 thiab siv standard GB / t15012.
German tus qauv:1.4876, x10nicralti32-20, American Standard no8800, 1.4876, lub teb chaws tus qauv gh1180, ns111, 0cr20ni32fe
Cov pa roj carbon C: ≤ 0.10, silicon Si: ≤ 1.0, manganese Mn: ≤ 1.50, chromium Cr: 19 ~ 23, nickel Ni: 30.0 ~ 35.0, aluminium al: ≤ 0.15 ~ 0.6, titanium Ti 5 ~ 0.6, 0. : ≤ 0.75, phosphorus P: ≤ 0.030, sulfur s: ≤ 0.015, hlau Fe: 0.15 ~ seem.
1.4876 corrosion resistant alloy muaj kev ua haujlwm kub zoo. Qhov kub ua hauj lwm kub yog 900 ~ 1200 thiab kub dabtsi yog khoov txoj kev yog 1000 ~ 1150 degrees. Yuav kom txo tau qhov sib txawv ntawm kev sib txhuam ntawm cov hlau, nws yuav tsum dhau los ntawm 540 ~ 760 degree rhiab heev cheeb tsam kom sai li sai tau. Intermediate softening annealing yog xav tau thaum ua haujlwm txias. Kev kho cua sov kub yog 920 ~ 980. Cov khoom siv tshuaj kub yog 1150 ~ 1205. Qhov kev siv vuam yog qhov zoo, thiab cov qauv siv vuam zoo.
Ceev: 8.0g / cm3, melting point: 1350 ~ 1400 ℃, tshwj xeeb kub peev: 500J / kg. K, resistivity: 0.93, elastic modulus: 200MPa.
1.4876 corrosion resistant alloy muaj zoo heev kev nyuaj siab corrosion kuj nyob rau hauv cov dej uas muaj chloride thiab tsawg concentration NaOH. Nws yog dav siv los tsim cov khoom siv kev ntxhov siab corrosion-resistant es tsis txhob ntawm 18-8 austenitic steel. Nws yog siv nyob rau hauv lub siab dej reactor evaporator, kub kub gas txias reactor, sodium txias ceev reactor tshav kub exchanger thiab superheated chav yeeb nkab nyob rau hauv lub hwj chim kev lag luam. Nws yog siv hauv HNO3 txias, acetic anhydride cracking yeeb nkab thiab ntau yam khoom siv hluav taws xob sib pauv hauv kev lag luam tshuaj.
